What You Need To Know About The Delta Variant

It is common for viruses to change through mutation, and new variants of a virus are expected to occur. These variants can affect the strength, symptoms, or transmission rate of the virus. There have been multiple variants of the virus that causes COVID-19 identified in the United States and globally throughout this pandemic. One variant that you may be hearing more and more about is the delta variant.

The highly transmissible delta variant of the COVID-19 virus was first identified in India and has now been reported in at least 104 countries. According to the Centers for Disease Control and Prevention (CDC), the delta variant is now the dominant strain of the virus, representing 51.7% of new COVID cases in the United States as of the week of July 3.

The delta variant is a cause of concern to health authorities because it is thought to be the most transmissible variant yet. According to the World Health Organization (WHO), the delta variant is estimated to be approximately 55% more transmissible than the alpha variant, which was first identified in Britain last year. Officials believe delta is more contagious because of its ability to partially evade the antibodies made by the immune system after a coronavirus infection or vaccination.

Many health experts fear the variant will cause a surge in new cases this fall, hitting the unvaccinated the hardest. Currently, only 48% of adult Americans are fully-vaccinated, well below the 70% most believe is needed to achieve herd immunity. In fact, areas in the U.S. with low vaccination rates are already beginning to see delta-driven outbreaks, and the number of COVID-19 cases has begun to climb again nationally.

The good news is that data suggests that several widely used shots, including those made by Pfizer-BioNTech, Moderna, Johnson & Johnson and AstraZeneca, appear to retain most of their effectiveness against the delta variant.

 

Flushing Hospital urges everyone eligible to get vaccinated if you have not already done so and encourage your family and friends to get vaccinated as well.  Vaccination is the best way to stop the spread of all the variants and reduce the odds that new, even more dangerous variants emerge.

Flushing Hospital Dispels Myths About The COVID Vaccine

There are many myths being circulated about the COVID-19 vaccine due to a spread of misinformation. It is important to know what is true and what is not to help you make an informed decision about getting vaccinated.

Myth:  I don’t need to get the vaccine if I already had COVID Is it true that the vaccine was produced too quickly and is unsafe because it wasn’t tested sufficiently?

Fact: The Centers for Disease Control and Prevention (CDC) recommends everyone receive the vaccine when it’s their turn, including those who have already had covid-19.

While it is true that those who had covid-19 may have developed some natural immunity, we don’t yet fully understand how long that immunity will last. The vaccine can boost any existing immunity without causing any harm.

What Is Herd Immunity?

The existence of COVID-19 has introduced us to many new terms that we may not completely understand. One of those terms is “herd immunity.”

Herd immunity describes how the spread of a contagious disease can be controlled after a large enough portion of the population, (referred to as “the herd”) becomes immune.

A disease is most contagious when everyone in the community is at risk of contracting it. If a sizable percentage becomes immune however, it makes it harder for the disease to reach those susceptible because the herd blocks its ability to reach them.  As a result, the entire community becomes better protected.

There are two ways to achieve herd immunity: vaccination or infection and recovery.

  • Vaccination – Vaccines create immunity without causing illness or resulting complications. Vaccines have successfully controlled deadly contagious diseases such as smallpox, polio, diphtheria, rubella and many others. Herd immunity by vaccination protects people who are unable to be vaccinated due to age or other conditions.
  • Natural infection – 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. For example, those who survived the 1918 flu (influenza) pandemic were later immune to infection to the H1N1 flu, a subtype of influenza A.

The percentage of a community that needs to be immune in order to achieve herd immunity varies from disease to disease. The more contagious a disease is, there will need to be a greater proportion of the population that is immune to the disease to stop its spread. For example, the measles is a highly contagious illness, therefore it’s estimated that 94% of the population must be immune to interrupt the chain of transmission.

It is important to note that while herd immunity can reduce the risk of getting a disease, it does not prevent it. Until an effective COVID-19 vaccine is developed, it is important to follow all safety guidelines to protect against the transmission of the virus, including:

  • Avoiding large events and mass gatherings.
  • Avoiding close contact with others, (within 6 feet).
  • Washing 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.
  • Wearing a face mask or covering in public spaces.
  • Covering your mouth and nose with your elbow or a tissue when you cough or sneeze.
  • Avoiding touching your eyes, nose and mouth.
  • Avoiding sharing dishes, glasses, bedding and other household items if you’re sick.
  • Cleaning and disinfect high-touch surfaces daily.
  • Staying home from work, school and public areas if you’re sick, unless you’re going to get medical care.
