Can COVID-19 virus infect again? OR Can COVID-19 virus get reactivated in human body?
क्या कोरोना से आप दुबारा संक्रमित हो सकते हैं ?
संछिप्त जवाब – जी हाँ , बिलकुल हो सकते है।
Short answer: Stay cautious. It depends on how much of COVID-19 infected you. Example, if you were exposed to 1mg of Coronavirus and your body was able to fight it, doesn’t mean that your body will be able to fight it again when exposed to 5mg of Coronavirus. Logic is simple – why do you need Flu vaccine every year?
Long answer:
Case #1: One study from Hong KongTrusted Source looked at data from 59 people with COVID-19, as well as pooled data from more than 60 studies, and found “the presence of viral RNA fragments or particles in stool up to 33 days after initial infection with SARS-CoV-2, with no evidence of virus being detected in respiratory tract samples,” Glatter said.
Case #2: Roughly 450 South Koreans tested positive for the virus again after meeting the criteria for recovery and being discharged from isolation. The Korea Centers for Disease Control and Prevention re-tested more than half of those people and found no evidence of the live virus circulating.
Peer-reviewed research studies have shown that viral fragments can circulate even after an individual is symptom-free. That doesn’t mean that people are still sick or infectious.

Case #3: Research at King’s College London also suggested levels of antibodies that kill coronavirus waned over the three month study.
But even if antibodies disappear, then the cells that manufacture them, called B cells, may still be around. B cells for Spanish Flu have been found in people 90 years after that pandemic.
If the same is true with Covid, then a second infection would be milder than the first.
It is also not understood what happens to T cells in the long term. But T cells against the original Sars (Severe Acute Respiratory Syndrome) have been found 17 years later.
