CDC Updates “How COVID is Spread” Webpage

In COVID-19, News by Mary Madison2 Comments

On October 5, 2020, CDC issued updated guidance to its How COVID-19 Spreads website, which includes information about the potential for airborne spread of the virus that causes COVID-19.  This updated guidance was announced via a Media Release.

“CDC continues to believe, based on current science, that people are more likely to become infected the longer and closer they are to a person with COVID-19.  Today’s update acknowledges the existence of some published reports showing limited, uncommon circumstances where people with COVID-19 infected others who were more than 6 feet away or shortly after the COVID-19-positive person left an area.  In these instances, transmission occurred in poorly ventilated and enclosed spaces that often involved activities that caused heavier breathing, like singing or exercise.  Such environments and activities may contribute to the buildup of virus-carrying particles.
CDC’s recommendations remain the same based on existing science and after a thorough technical review of the guidance.
People can protect themselves from the virus that causes COVID-19 by staying at least 6 feet away from others, wearing a mask that covers their nose and mouth, washing their hands frequently, cleaning touched surfaces often and staying home when sick.”

The Washington Post reports that “The update follows an embarrassing incident last month (September 21, 2020) when the agency removed a draft that had not gone through proper review and was posted in error. The draft’s wording included a reference to aerosols — tiny droplets that can stay in the air, potentially traveling a significant distance. Officials said the draft was removed because they feared the language could be misinterpreted as suggesting that airborne transmission is the main way the virus spreads.”

Here’s what you’ll now see on the How COVID-19 Spreads website:

      This answer is from the CDC as of September 10, 2020: Can I get reinfected with COVID-19?
      At this time, we do not know if someone can be re-infected with COVID-19. Data to date show that a person who has had and recovered from COVID-19 may have low levels of virus in their bodies for up to 3 months after diagnosis. This means that if the person who has recovered from COVID-19 is retested within 3 months of initial infection, they may continue to have a positive test result, even though they are not spreading COVID-19.

      There are no confirmed reports to date of a person being reinfected with COVID-19 within 3 months of initial infection. However, additional research is ongoing. Therefore, if a person who has recovered from COVID-19 has new symptoms of COVID-19, the person may need an evaluation for reinfection, especially if the person has had close contact with someone infected with COVID-19. The person should isolate and contact a healthcare provider to be evaluated for other causes of their symptoms, and possibly retested.

      In the past 2 days, there have been reports of at least 2 individuals in the U.S. that had COVID illness a couple of months ago and are sick again – with positive COVID-19 tests. There have also been reports of re-infection from other countries in the world. More research is needed!
