As scientists are trying to make sense of SARS-CoV-2, the virus that causes Covid-19, a new study has found that not only is reinfection possible, but that individuals may actually experience more severe symptoms the second time they are infected.

The study, published in The Lancet Infectious Diseases, reports on the first confirmed case of SARS-CoV-2 reinfection in the US, and cautions that exposure to the virus and subsequent antibodies may not guarantee immunity against a second reinfection.

Alternatively, they proposed that it may have been a more virulent (more harmful) strain of the virus that led to severe infection. A previous Health24 article explains that due to the virus’s complex biology, it is constantly mutating. Scientists are therefore trying to stay ahead, as the most worrying mutations could cause the virus to evade immune systems, as well as vaccines and antibody therapies.

Earlier this month, Health24 also reported on the "silent" reinfection of two Indian healthcare workers who were infected with a completely different strain of the virus the second time around.
