Another reason the CDC advises against asymptomatic testing for 90 days after having COVID-19 is that if you are infected, your immune system is going to generate antibodies, so your immunity to the virus will be boosted, says Mansoor Amiji, university distinguished professor of pharmaceutical sciences and chemical engineering at Northeastern. One 2022 study states that the Omicron variant appears to cause less severe symptoms and have a shorter duration than previous variants.

Neil Maniar, director of the Master of Public Health program and a professor of the practice in the Bouv College of Health Sciences, and Mansoor Amiji, Distinguished Professor and Chair of the Department of Pharmaceutical Sciences.

They form part of hidden defences against the virus which are not as easily studied like antibodies are. How Long Does the Omicron Variant Last on Surfaces? And scientists have already confirmed that Omicron has earned special attention at this stage of the pandemic, as evidence suggests that the strain spread more effectively than others, demonstrating an ability to reinfect someone who had previously experienced a COVID-19 illness, even sometimes within the CDC's official 90-day reinfection window. According to the Our World in Data COVID-19 database, the number of confirmed Omicron cases reported between December 2021 and March 2022 exceeded all previously reported cases. It has not been 90 days since its discovery in the UK in . The stealth variant COVID-19, also known as BA.2, was responsible for almost 4 percent of reported cases last week, according to data from the Centers for Disease Control and Prevention (CDC). The toxic train derailment in Ohio was only a matter of time, Northeastern experts say. Prof Alex Dornburg, assistant professor of bioinformatics and genomics at the University of North Carolina at Charlotte, said: As new variants arise, previous immune responses become less effective at combating the virus. Omicron is a variant of SARS-CoV-2, the virus that causes COVID-19. There is a possibility of becoming impacted by Omicron when it comes to reinfection, but there isn't enough data yet to determine how likely this would be in reality and certain trends elsewhere in the pandemic suggest that any likelihood of an Omicron reinfection for any given person may further be on the decline. However, while data on the effectiveness of booster vaccines that target the Beta protein spike is still limited, the Moderna booster vaccines appear to be more effective. Scientists first detected these lineages in January and February 2022 in South Africa. The good news is that people are very unlikely to pick up the bug twice in one year, the researchers said.

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. Amiji adds that as vaccines continue to aid an ever-expanding amount of the population in blocking potential viral infections, it makes sense that SARS-CoV-2 strains will likely continue to mutate in response. This is a change to the previous methodology from the UK Health Security Agency (UKHSA), by which people who tested positive for Covid-19 were counted only once in case numbers published on the daily dashboard, when they first tested positive.
