Researchers have found 4 symptoms of the emerging corona virus infection, which causes Covid-19 disease, that are related to the formation of the body. High levels of antibodies to the virus continue for 3 months.

The presence of high levels of antibodies means that the person has immunity to infection with the emerging coronavirus - its scientific name is "SARS-CoV-2" - for a second time.

The study was conducted by researchers from the University of Wisconsin in the United States and published as a preliminary version (not accepted in a medical journal), and has not yet been subjected to peer review.

The researchers analyzed the blood tests of 113 patients infected with the Coronavirus after 5 weeks of recovering from their disease, and then again 3 months after their illness.

They found that people who had Covid-19 and were hospitalized had higher antibody levels than others, and in general the levels of antibodies increased with the severity of Covid-19.

But for people who were infected with Covid-19 and were not hospitalized, the researchers noted that 4 of the symptoms are associated with persistently high levels of antibodies to the Corona virus, and they are:

1- Fever

2- Abdominal pain

3- Diarrhea

4- Decreased appetite

This means that the appearance of these symptoms on you while you are sick can be a sign that you are likely to have longer immunity against Corona.

Overcoming the pandemic

The researchers said that permanent immunity - which is often assessed by persistent antibodies - will be necessary to overcome the Covid-19 pandemic.

In severe acute respiratory syndrome (SARS), antibodies to viruses persist in the majority of patients for at least 3 years after the disease.

On the other hand, little is known about the emerging corona virus, but some reports indicate that immunity may last for at least 6 months.

However, other reports indicate that the antibodies against SARS-Cove-2 could decrease in the first few months, as some patients become negative.
