Even if the world has a lot more ways to fight the coronavirus than it did two years ago, we shouldn’t underestimate what COVID can do to our bodies. This is available even in the case of developing a mild illness after infection.
Let’s say a guy develops a sore throat, a little headache, and loss of smell. He otherwise feels fine, goes on with his work remotely, and so on. He fully recovers a few days later, without the need for hospitalization. He’s obviously tempted to consider that COVID didn’t do anything bad to his body. But a new study is there to contradict him a bit.
Some immune cells could be more prone to inflammation months after COVID infection
According to Gizmodo, a new study published in the journal Mucosal Immunology reveals that some immune cells are more prone to inflammation three to five months after a person faces a mild COVID illness. But the good news is that the unpleasant situation goes away just a year later.
The researchers collected blood samples from 68 individuals who had been dealing with mild COVID illness. The samples were compared to those of individuals who didn’t get COVID. The same samples were collected three to five months and a year after the infection.
Craig Wheelock, the author of the study, told Gizmodo via email:
Even in mild cases of disease, we observe an altered response in immune cells several months after the resolution of infection,
In other words, even after people return to health, their immune system evidences an altered function for at least several months.
More research is still needed for scientists to understand how the possible inflammation could be connected to post-COVID symptoms. The new study was conducted by the Karolinska Institute in Sweden, the Helmholtz Center Munich and the Technical University of Munich.
