Since December 2020, we have been hearing reports of a new variant of the coronavirus that causes COVID-19. New variants have been identified since and are being closely monitored.
The new variants bring about even more stress as we continue to navigate the pandemic. Are we more likely to get sick? Will the vaccines work against the variants? Should we do anything differently to keep ourselves and our families safe? These are questions many of us are asking, and we are here to help answer them based on the current information we have.
About the Variants
Variants of viruses occur when there is a mutation — or change — to the virus’s genes. Virus mutation is common and not unexpected. For example, because flu viruses change often, doctors recommend a flu shot once a year to protect you. Here is what we know about the COVID-19 variants:
- Alpha: This variant was first detected in the United States in December 2020. It was initially detected in the United Kingdom.
- Beta: This variant was first detected in the United States at the end of January 2021. It was initially detected in South Africa in December 2020.
- Gamma: Gamma was first seen in travelers from Brazil in early January, who were tested during routine screening at an airport in Japan.
- Delta: The delta variant was first detected in the United States in March 2021. It was initially identified in India in December 2020. In the United Kingdom, 99% of COVID-19 cases are currently attributed to the delta variant. This is considered a highly contagious strain.
- Delta plus: The delta plus variant is a mutation of the current delta variant’s spike protein that binds to a cell’s receptors and allows it to enter. (Read more here .)
- Lambda: The earliest documented samples of the lambda variant date from August 2020, but it was flagged as a “variant of interest” by the World Health Organization on June 14, 2021. It has been spreading rapidly in South America, particularly Peru. It is more contagious than the Alpha and Gamma variants.
Are the Variants More Contagious?
According to the CDC, these variants seem to spread more quickly and easily than other variants, which may lead to more cases of COVID-19. More cases can lead to more hospitalizations, and potentially more deaths.
Are the Variants More Dangerous?
The delta variant may be causing more severe infection in some patients because of its ability to replicate more quickly. As with the original version of COVID-19, the risk is highest for elderly people and those who have significant underlying health conditions. However, a virus being more contagious and just as dangerous will in itself lead to more deaths in unvaccinated populations.
Do the Vaccines Protect Against Variants?
Vaccines offer high protection against serious illness with COVID-19, including infections caused by these variants. They also reduce the risk of becoming infected at all. They don’t eliminate all risk, but they provide the best safety net possible as the variants continue to spread quickly throughout our communities.
Widespread vaccinations reduce the likelihood that the virus will continue to mutate and cause more variants. That’s why it’s so important to get your shot once you’re eligible, and encourage your loved ones to do the same.
Keeping You and Your Family Safe from COVID-19
As COVID-19 and its variants continue to circulate, the advice remains largely the same. Follow these steps to help keep you and your family healthy and safe:
- Avoid crowds and poorly ventilated indoor spaces
- Get a COVID-19 vaccine
- Stay six feet apart from others who don’t live with you
- Wash your hands often with soap and water, and use hand sanitizer
- Wear a face mask that covers your nose and mouth
