Were learning how and when to test ourselves for the virus that causes COVID-19 to minimize the risk of spreading it when traveling, visiting family, or going to sporting events or concerts. For example, if you became infected from the BA-2 subvariant, this doesnt prevent you from getting infected with BA-4 or BA-5, says Neil Maniar, professor of practice in the Department of Health Sciences. This first became clear when the variant was identified in South Africa and researchers observed higher-than-expected rates of reinfection among people who had previously had COVID-19. doi:10.1001/jamanetworkopen.2021.43151, Kompaniyets L, Agathis NT, Nelson JM, et al. Clinical Characteristics and Outcomes of Hospitalized Women Giving Birth With and Without COVID-19. Attributes and predictors of long COVID. Does it change anything? New variants like BA-4 or BA-5, which were unheard of earlier this year, are now circulating in the United States, and they may not be prevented by vaccines, boosters, or the antibodies that you develop when youre infected by another variant. Amiji says COVID-19's subvariants typically cause more upper respiratory issues than lower, making the symptoms less serious. "We all still have to live in a way where we try to minimise our risk even though we are transitioning towards something looking like the way life used to be.". Its a wakeup call and an opportunity, according to experts, Fact checking Don Lemon: Women reach their prime later in life, Northeastern experts say.

The thinking when the recommendation was written was also that the antibodies developed during the infection could protect you from getting reinfected within 90 days. A small Danish study published in February which is yet to be peer reviewed found reinfection with Omicron BA.2 following BA.1was possible, but happened rarely, and most reinfections occurred in unvaccinated people. This variants infectiousness including its ability to evade immune systems and prevent long-lasting immunity for those people who are infected with it is one of the reasons why its been able to persist and come back, he explains. "We all do need to continue to think about others around us, and think about what we need to do to protect ourselves.". "The factors that can influence that include how long it's been since your first infection the longer it's been, the lower your antibody levels will be because they decrease over time," she said.
