African Americans Disproportionately Dying

Posted on by

African Americans are dying from the coronavirus at almost 3 times the rate of their white counterparts.

Black and Hispanic Americans were disproportionately more likely to die of COVID-19 during the spring and summer months indicating that the coronavirus’s toll is falling most heavily on underserved and minority communities, according to the Centers for Disease Control and Prevention (CDC).

When you consider that African Americans represent 12.5 percent of the population, but account for almost 23 percent of all coronavirus deaths, the COVID-19 pandemic is disproportionately decimating the black working class communities across the country.

Coronavirus has become the third leading cause of death of citizens in the United States in calendar year 2020. The virus has killed more than 300,000 since arriving on U.S. shores, making it a leading cause of death after heart disease and cancer.

In 2018, the 10 leading causes of death for all Americans (heart disease, cancer, unintentional injuries, chronic lower respiratory diseases, stroke, Alzheimer disease, diabetes, influenza and pneumonia, kidney disease, and suicide) remained the same as in 2017. The 10 leading causes accounted for 73.8% of all deaths in the United States in 2018.

The Centers for Disease Control and Prevention (CDC) maintains a provisional death count related to COVID-19. The deaths counted in that data are well below those compiled from the state and county levels because the provisional count is based on death certificates that may take weeks to filter up to the federal agency.

With respect to controlling the pandemic, Martin Luther King Jr. once declared “Whatever affects one directly, affects all indirectly.” This is definitely true for epidemiology and controlling the pandemic. To protect the health of all us, we must insure the health of the most vulnerable among us.

How to control COVID-19 is not a mystery — it requires wearing masks, social physical distancing of 6 feet, frequent washing of hands, widespread contact tracing and COVID testing and widespread vaccination. However, these efforts to combat the pandemic require people to trust the science and those behind the public health measures.

In the nationwide fight against the COVID-19 pandemic, well founded mistrust has developed over decades by African Americans of the government, public health officials and ‘the science’ can and has killed a disproportionate share of working class Blacks and other people of color.

Masks Protect Those Around You

Posted on by

COVID-19 spreads mainly from person to person through respiratory droplets. Respiratory droplets travel into the air when you cough, sneeze, talk, shout, or sing. These droplets can then land in the mouths or noses of people who are near you or they may breathe these droplets in.

Masks are a simple barrier to help prevent your respiratory droplets from reaching others. Studies show that masks reduce the spray of droplets when worn over the nose and mouth.

You should wear a mask, even if you do not feel sick. This is because several studies have found that people with COVID-19 who never develop symptoms (asymptomatic) and those who are not yet showing symptoms (pre-symptomatic) can still spread the virus to other people. The main function of wearing a mask is to protect those around you, in case you are infected but not showing symptoms.

It is especially important to wear a mask when you are unable to stay at least 6 feet apart from others since COVID-19 spreads mainly among people who are in close contact with one another (within about 6 feet).

Your mask offers some protection to you

A cloth mask also offers some protection to you too. How well it protects you from breathing in the virus likely depends on the fabrics used and how your mask is made (e.g. the type of fabric, the number of layers of fabric, how well the mask fits). CDC is currently studying these factors.

Who should or should not wear a mask

CDC guidance is that everyone 2 years of age and older should wear a mask in public settings and when they are around people who do not live in their household.  However, according to CDC, masks should not be worn by:

  • Children younger than 2 years old
  • Anyone who has trouble breathing
  • Anyone who is unconscious, incapacitated or otherwise unable to remove the mask without assistance
  • Wearing masks may be difficult for some people with sensory, cognitive, or behavioral issues. If they are unable to wear a mask properly or cannot tolerate a mask, they should not wear one,

Key Takeaways:

  • People age 2 and older should wear masks in public settings and when around people who don’t live in their household.
  • Masks offer some protection to you and are also meant to protect those around you, in case you are unknowingly infected with the virus that causes COVID-19.
  • A mask is NOT a substitute for social distancing. Masks should still be worn in addition to staying at least 6 feet apart.
  • Wash your hands with soap and water for at least 20 seconds or use hand sanitizer with at least 60% alcohol after touching or removing your mask.
  • Postponing holiday travel & staying home is the best way to protect yourself & others from COVID19. If you decide to travel internationally, check out CDC’s testing recommendations to help make travel safer. 
  • Masks may not be necessary when you are outside by yourself away from others, or with other people who live in your household. However, some localities may have mask mandates while out in public and these mandates should always be followed.

Vaccination and Wearing Masks

Posted on by

“Once enough people have some immunity, either because of previous infection or because of vaccination, the virus will have a hard time spreading through the community.” Consumer Reports

Researchers hope that Americans getting vaccination will be sufficient to end the pandemic once there is sufficient supply and enough pf the population gets vaccinated.

In trying to understand the readily available vaccine information and how it will affect the lives of Americans, Consumer Reports has reviewed government guidance and consulted with public health experts to provide insight to their readers about the vaccine candidates.

Vaccination equals two doses

Vaccines require two doses—an initial shot and a booster, taken several weeks later. Generally with a two-dose vaccine, it takes about two weeks from the second dose for a vaccine’s protection to fully kick in, according to Natalie Dean, PhD, an assistant professor of biostatistics specializing in infectious disease and vaccine development at the University of Florida.

Though two doses are necessary, the FDA’s analysis of the Pfizer vaccine indicates that people appear to be somewhat less likely to get COVID-19 within two weeks of receiving the first dose.

It’s unclear how long protection from that first dose may last. And the second dose is still required for full protection, to ensure a more durable immune response. 

Halting the virus transmission

It is not known definitely whether getting vaccinated will prevent you from spreading the coronavirus to others. Thus, preventive measures such as social distancing, washing hands, and wearing a mask will remain important even after you get vaccinated, according to the CDC.

More research is required before scientists can say exactly how many people need to be vaccinated to achieve “herd immunity “. It’s possible that with extremely effective vaccines showing 95 percent efficacy, we might hit the point where communities are protected by the time somewhere between 60 and 70 percent of people have been vaccinated, according to Kathleen Neuzil, MD, a professor of vaccinology and director of the Center for Vaccine Development and Global Health at the University of Maryland in Baltimore. 

It will be possible for vaccines, as long as Americans get vaccinated, to have a significant impact on ending this pandemic.

Severe allergic reactions

In the U.K., public health regulators have advised that anyone with a history of a severe, potentially life-threatening allergic reaction to a vaccine, medicine, or food should not receive the vaccine. Two healthcare workers were reported to have had severe allergic reactions after receiving the vaccine. Public health experts worry that the reports could frighten people with allergies and make them think they should avoid getting the vaccine.

From Pfizer’s vaccine trial results, there were no severe allergic reactions. Deliberately, the trials excluded people who had previously had severe allergic reactions to vaccines, a Pfizer scientist said during the advisory panel’s discussion.

The FDA plans to advise that people who are allergic to components of the vaccine should not get it, an agency scientist explained. The FDA’s earlier review of Pfizer’s trial data found slightly more potential minor allergic reactions in the group that received the vaccine than in the placebo group, but none of these were severe, and none occurred immediately after people received their doses of vaccine.

Vitamin D: Powerful Protection vs. Viruses

Posted on by

A new study from Spain looked at 216 hospital patients with COVID-19 and found that 80 percent didn’t have adequate levels of vitamin D in their blood, according to Healthline.com.

Recent research discovered a correlation between vitamin D deficiency and a higher risk of COVID-19. Now, another new study has found the same — noting that more than 80 percent of people with COVID-19 didn’t have adequate levels of the “sunshine vitamin” in their blood.  “It looks like patients with a poor vitamin D status may have more severe COVID-19,” said Dr. Hans Konrad Biesalski, a professor at the University of Hohenheim who has evaluated vitamin D and COVID-19..

Vitamin D is a potent weapon against viruses and crucial for immune health — make sure you’re getting enough

There appears to be strong evidence that Vitamin D plays a critical role for your body’s immune system and can ward off respiratory infections. Vitamin D does not effect the viruses, but effects the way our immune system handles infections including viruses.

Boosting your immune system is one of the best things you can do because it is your body’s key defense when it comes to fighting a virus. Even if you are exposed to a virus and if your immune system is strong, you have a better chance of not getting sick.

A major 2017 study published in the British Medical Journal looked at vitamin D’s effectiveness against viral infections. Researchers analyzed 25 clinical trials that included 11,321 people. The data came from 14 countries, including the U.S., England, Japan, Australia, Canada, and Italy.

The study found that taking vitamin D supplements cuts in half the risk of respiratory infections caused by viruses.[1]

Many people recommend that people at high risk for COVID-19 — older adults, those with underlying conditions, and people in nursing homes — can be treated with vitamin D.  “Vitamin D treatment should be recommended in COVID-19 patients with low levels of vitamin D circulating in the blood since this approach might have beneficial effects in both the musculoskeletal and the immune system,” Hernández said in a statement.

Many Americans have a vitamin D deficiency

Vitamin D supplements should be considered one of the many tools that might help when conventional therapies are not enough. Research has found that vitamin D improves viral immunity by strengthening your mucus membranes.

Vitamin D is a key nutrient for your immune system. Once thought as the vitamin for strong bones, vitamin D actually does a lot more for your body — including support your immune system.

The coronavirus and other viruses get into your body through entry points that are covered with mucus membranes. They include your nose, mouth, eyelids, lungs, trachea (windpipe).

A lab study at the University of Illinois found that vitamin D helps mucus membranes provide a stronger barrier to viruses by increasing the antimicrobial compounds in them.

With coronavirus pandemic, researchers have not yet had time to fully test vitamin D directly against it. But they say there’s no reason to think that it would not work just as well against coronavirus as it does against the flu, colds, and other upper respiratory viruses.  “Very low vitamin D status has lots of negative consequences and this could be the case for COVID-19, but that’s not the same as saying that routine vitamin D supplementation will prevent severe infection,” he told Healthline.

Coaches Voice Stopping College Basketball Season

Posted on by

Stop the season. Stop the games, men’s and women’s college basketball, right now, according to several prominent college basketball coaches.

The college basketball season officially began in late November — yet, 33 men’s teams still have not played one game because of COVID-19 interruptions. A number of prominent voices in the college basketball game are wondering if the season should be stopped or postponed with the COVID-19 crisis anything but under control, especially with the physical, emotional and mental toll it has on college student athletes.

Many states has declared the coronavirus outbreak a public health emergency and have implemented restrictions on travel, business and public gatherings. Additionally, there are approximately 2,000 deaths a day and nearly 300,000 new COVID-19 infection cases daily across the country. Nationally and locally, communities have experienced a spike in positive COVID-19 cases since late November. Local and state governments and public health officials are now predicting COVID-19 cases will continue to spike even higher in January following the Christmas and New Year’s holidays.

The most vocal advocate for stopping (or pausing) the men’s and women’s college basketball season is Duke’s basketball coach Mike Krzyzewski. Coach Krzyzewski wants the NCAA “…for the mental health and safety of our players and staff, to assess where we’re at” with with regards to the college basketball season and in light of more COVID-19 game cancellations.

The Duke men’s basketball program will forgo its remaining nonconference regular-season basketball games. The decision was made out of an abundance of caution due to the COVID-19 pandemic and to allow the Blue Devils’ players time over the holidays to spend with their families, according to a release from the university.

Stopping the Exponential Rise in Cases

Posted on by

“Cases are rising. Hospitalizations are increasing, Deaths are increasing. We need to try to bend the curve, stop this exponential increase,” says Dr. Henry Walke, the CDC’s COVID-19 Incident Manager.

As COVID-19 cases continue to soar, it took the U.S. more than eight-and-a-half months to reach 8 million cases but less than two months to double that number.

As a result, hospitals across the U.S. are facing dire shortages of beds for critically ill coronavirus patients as the post-Thanksgiving holiday surge shows no sign of relenting, new data shows from the U.S. Department of Health and Human Services.

About 1 in 8 U.S. hospitals had little or no intensive care unit space available last week the data showed. And for the sixth consecutive day, the US reported a record high number of COVOD-19 patients in US hospitals: more than 108,000 nationwide, according to the Covid Tracking Project.

Public health experts say the number of hospitals struggling with intensive care unit capacity to accommodate the nation’s sickest patients likely will increase following another week of record COVID-19 cases.

As cases continue to soar, it took the U.S. more than eight-and-a-half months to reach 8 million cases but less than two months to double that number.

CDC and many states advise not to travel

As Americans contemplate whether to proceed with their holiday season or New Year’s travel plans, the U.S. Centers for Disease Control and Prevention (CDC) is urging citizens not to travel or to get tested before or is urging Americans who go against its advice to get tested for COVID-19 twice in a bid to make travel safer.

The agency says travelers should get a COVID-19 test one to three days before travel and three to five days after travel, regardless of their destination.

Additionally, some states are reimposing stay-at-home orders for their residents and travel restrictions ahead of the winter holidays.

While other states, such as Hawaii for example, require inbound travelers to show proof of a negative COVID-19 test upon arrival or require those without results before their arrival to quarantine for 14 days.

What to do

This is one time Americans should heed CDC urging to not to travel and stay home as the best way to protect yourself and others this year; or to get tested for COVID-19 twice in a bid to make travel safer.

Dr. Fauci Advises Staying Home for the Holidays

Posted on by

Traveling and congregating together is unsafe this holiday season according to Dr. Anthony Fauci, Director of the National Institute of Allergy and Infectious Diseases

It’s clear that “even modest size gatherings of family and friends in a home” are contributing to spread, Fauci said. “We’re starting to see infections that are emerging from what otherwise seemed like benign settings, namely a typical gathering of 10 or so people in a social setting,” he said.

But in addition to the number of guests, it’s important to consider where people are traveling from, and the infection rates in their areas, Fauci said. Travel increases your chances of spreading or getting Covid, according to the CDC.

Expected COVID-19 infection spikes due to Christmas and Hanukkah will likely be more severe than the levels experienced following Thanksgiving, because people are typically together for longer, often indoors and sharing food and drinks, Fauci said.

Fauci has warned that the U.S. could see a “surge upon a surge” of Covid-19 cases following Thanksgiving and heading into Christmas. The month of December could be a time of “precarious risk” as people begin shopping for Christmas gifts in stores and host parties for New Year’s Eve, he said.

Staying home during the holidays, wearing a mask whenever you’re around people from outside your household and maintaining proper hand hygiene are the best ways to protect yourself and reduce the community spread of COVID-19, according to the Centers for Disease Control.

mRNA Vaccine Safe and Its Side Effects

Posted on by

Moderna and Pfizer COVID-19 vaccine trials show that side effects are common in participants and it appears that the more significant symptoms develop following the second dose.

The Pfizer-BioNTech’s mRNA coronavirus vaccine (BNT162b2) is both safe and effective, according to the U.S. Food and Drug Administration (FDA). FDA said results from Pfizer’s large, ongoing study showed the vaccine, which was co-developed with Germany’s BioNTech, demonstrated more than 95% efficacy across people of different ages, races and underlying health conditions, including diabetes and obesity. And partial protection from coronavirus appears to begin 12 days after the first dose, according to Pfizer. Consequently, Pfizer requested and the vaccines are expected to be approved for emergency use authorization (EUA) by the FDA as early as this week.

And this week, a committee of leading U.S. vaccine scientists recommended that the Food and Drug Administration authorize the first COVID-19 vaccine for Americans.

FDA approval of a drug means that the agency will have determined, based on substantial evidence, that the drug is effective for its intended use, and that the benefits of the drug outweigh its risks when used according to the product’s approved labeling. Approval of the he vaccine will help reduce the risk of disease. The vaccine works with the body’s natural defenses to safely develop protection (immunity) to disease, according to the FDA’s website.

How an mRNA vaccine works

Messenger RNA vaccines, called mRNA for short, is a new kind of vaccine technology that has never before been licensed in the U.S. mRNA vaccines contain material from the virus that causes COVID-19 that gives our cells instructions for how to make a harmless protein that is unique to the virus. The objective of a vaccine is to teach your immune systems how to recognize and fight the virus that causes COVID-19, according to the Centers for Disease Control and Prevention.

Messenger RNA vaccines aren’t like past seasonal influenza vaccines. An mRNA vaccine is essentially just a piece of genetic code that contains instructions for our body. The mRNA tells our cells to make a protein — the same protein that is the spike on top of the actual coronavirus. This is what triggers the immune response in these types of vaccines.

In contrast, past seasonal influenza vaccine puts a weakened or inactivated virus into your body to trigger an immune response, which then produces antibodies. Those antibodies are what ultimately protects you from getting infected if you ever encounter the real virus.

It typically takes a few weeks for the body to build immunity against COVID-19 infection after vaccination. And after vaccination, the process of building immunity can cause symptoms or “side effects”. These symptoms are normal and are a sign that the body is building immunity.

Side effects

Sometimes the vaccine process of teaching your immune system how to react to the virus can cause symptoms. These symptoms are normal and are a sign that the body is building immunity. Moreover, no major safety issues were uncovered and common vaccine-related side effects like fever, fatigue and injection site pain were tolerable, according to the FDA.

The most common vaccine side effects were injection site reactions (84.1%), fatigue (62.9%), headache (55.1%), muscle pain (38.3%), chills (31.9%), joint pain (23.6%), and fever (14.2%), acc riding to the report submitted to the FDA.

Severe adverse reactions occurred in 0.0% to 4.6% of participants and appeared were more frequent after the second dose than after the first. The frequency of serious adverse events was low (<0.5%), without meaningful imbalances between study arms.

Although some COVID-19 trial participants reported COVID-like symptoms, it is impossible to contract the coronavirus from the vaccine, because the mRNA vaccines develop by Pfizer and Moderna don’t use the live virus. 

Bottomline

Getting vaccinated is one of many steps you can take to protect yourself and others from COVID-19.  Vaccines work with your immune system so your body will be ready to fight the virus if you are exposed.

Inflammation and COVID-19

Posted on by

Stay Away From Anything That Causes Inflammation

Medical experts are conveying to avoid anything that causes inflammation during this coronavirus pandemic, but some people have genes that make them more likely to experience inflammation. In 2019, scientists discovered that the coronavirus can trigger an inflammatory response making the symptoms and illness more severe .

From mild stress to chronic health conditions, inflammation can and will wreak havoc on your body and mind. Inflammation is caused by a complex mix of genetic and environmental factors, which can make it very difficult to address – especially while you’re suffering from exhaustion, depression, or any other inflammation-related symptoms.

Excessive immune response related to COVID-19

Every week, more is being learned about the incredible physiological harm that the coronavirus is capable of doing to those infected. This is the critical reason why this virus should not be taken likely.

Some clinicians suspect the driving force in many gravely ill patients’ downhill trajectories is a disastrous overreaction of the immune system known as a “cytokine storm.” Cytokine storm is a hyperinflammatory condition caused by an overactive immune system.  According to scientific research, a cytokine storm is a driving force in COVID-19 mortality rates.

Cytokines are chemical signaling molecules that guide a healthy immune response; but in a cytokine storm, levels of certain cytokines soar far beyond what’s needed, and immune cells start to attack healthy tissues. Blood vessels leak, blood pressure drops, clots form, and catastrophic organ failure can ensue. This can cause inflammation and damage to the lungs and other organs.

Corticosteroids

Doctors have used a class of medicines called corticosteroids – including one called dexamethasone – to help tame that response. These are medications that have been around for a long time and are readily available. “We know this medication very well. It’s been used for many other purposes, and we know the side effects profile and what it can do to the body,” pulmonary and critical care physician Lokesh Venkateshaiah, MD says.

Its use to treat COVID-19 stems from the success of the RECOVERY trial carried out by researchers in the United Kingdom. In the study, hospitalized patients with COVID-19 who received dexamethasone for up to 10 days were less likely to die than those who didn’t. That benefit was only seen in very sick patients – those who had oxygen levels less than 93% or needed supplemental oxygen.

But, doctors have to be careful with dosing. “Overdoing it with this drug ­can potentially put patients at risk for new infections, especially bacterial infections, or even fungal infections,” Dr. Venkateshaiah cautions.

COVID-19 fatigue

Yet after more than ten months, Americans are getting COVID-19 fatigue. Much of the current rise in COVID-19 infections is due to community spread. Taking precautions to prevent the spread of COVID-19 is critical, particularly as the virus continues to evolve.

Your best defense to avoid serious illness and against the physiological harm caused by COVID-19 is to remain vigilant. You must continue to wear a mask, maintain physical distancing and disinfect high-touch surfaces daily. Additionally, you must get vaccinated for the seasonal influenza, wash your hands regularly and stay away from others if you are feeling ill.

COVID-19 vs Seasonal Influenza

COVID-19 symptoms generally appear two to 14 days after exposure. And, with COVID-19, you may experience loss of taste or smell. COVID-19 is more contagious and spread more quickly than the seasonal flu. Severe illnesses, such as lung injury, may be more frequent with COVID-19 than with the flu. The death rate also appears to be higher with COVID-19 than the flu.

Wearing masks

Wearing a cloth mask has been shown to help decrease the spread of COVID-19. Research shows that a significant number of people who have COVID-19 do not have any symptoms and are considered asymptomatic. These people may not know they are transmitting the virus to others when they talk, sneeze or cough, or raise their voice, such as with singing or shouting.

You should wear a cloth mask to reduce the chance of transmitting respiratory droplets to others around you. You wear a mask to protect others, and they wear a mask to protect you.

Herd Immunity and the Vaccine

Posted on by

Herd immunity occurs when a large portion of a community ― the herd ― becomes immune to a disease, according to the Mayo Clinic. This makes the spread from person to person unlikely. As a result, the whole community becomes protected — not just those who are immune.

Two paths to herd immunity — vaccines and infection.

Vaccines create immunity without causing illness or resulting complications. Herd immunity makes it possible to protect the population from a disease, including those who can’t be vaccinated, such as those with compromised immune systems.

Herd immunity can also be reached when a sufficient number of people in the population have recovered from a disease and have developed antibodies against future infection.

Experts estimate that 70% of the U.S. population — more than 200 million people — would have to recover from COVID-19 to create herd immunity and halt the epidemic. This amount of infection could lead to serious and potentially long-term complications and millions of deaths.

Since the risk of developing dangerous symptoms from COVID-19 may be greater in people who are older (over 65) or in people of any age who have other serious underlying health problems, such as heart or lung conditions, weakened immune systems, severe obesity, or diabetes. And if many people become seriously ill with COVID-19 simultaneously, the nation’s health care system could quickly become overwhelmed.

Until there is widespread COVID-19 vaccinations, it’s crucial to slow the spread of the COVID-19 virus and protect individuals at increased risk of severe illness, including older adults and people of any age with underlying health conditions. To reduce the risk of infection:

  • Avoid large events and mass gatherings.
  • Avoid close contact (within about 6 feet, or 2 meters) with anyone who is sick or has symptoms.
  • Stay home as much as possible and keep distance between yourself and others (within about 6 feet, or 2 meters) if COVID-19 is spreading in your community, especially if you have a higher risk of serious illness. Keep in mind some people may have the COVID-19 virus and spread it to others, even if they don’t have symptoms or don’t know they have COVID-19.
  • Wash your hands often with soap and water for at least 20 seconds, or use an alcohol-based hand sanitizer that contains at least 60% alcohol.
  • Wear a cloth face covering in public spaces where it’s difficult to avoid close contact with others, especially if you’re in an area with ongoing community spread. for health care providers.
  • Cover your mouth and nose with your elbow or a tissue when you cough or sneeze. Throw away the used tissue.
  • Avoid touching your eyes, nose and mouth.
  • Avoid sharing dishes, glasses, bedding and other household items if you’re sick.
  • Clean and disinfect high-touch surfaces, such as doorknobs, light switches, electronics and counters, daily.
  • Stay home from work, school and public areas if you’re sick, unless you’re going to get medical care. Avoid public transportation, taxis and ride-sharing if you’re sick.

To reduce the spread of COVID-19, everyone needs to continue to use masks, exercise proper hand hygiene, limit travel, avoid congregating, and maintain appropriate social distancing.
