How many times can you get reinfected with COVID? Here's what experts say

Raw Story  

For many of those who have tested positive for COVID-19 this summer, this isn't their first rodeo. Deepta Bhattacharya, associate professor of immunobiology at the University of Arizona who previously co-authored a paper in 2020 that suggested that immunity to COVID-19 lasts "at least several months after SARS-CoV-2 infection," told Salon the answer to how many times a person can get reinfected will depend on how the virus keeps mutating. "The key thing that has changed — it's not so much that the immune response is fading out so quickly, it is that the virus is mutating to escape from it," Bhattacharya said. "If you did recover from a prior infection, even if it was the original strain, and then you got hit with omicron, there is still some protection — and your odds of getting really sick and landing in the hospital are still lower," Bhattacharya noted. "If you caught delta towards the end of its wave in October you could totally get infected again in January by omicron because omicron is really different from delta," Bhattacharya said.
