Researchers have found 4 symptoms of infection with the emerging coronavirus that causes Covid-19 disease, which are related to the formation of the body, high levels of antibodies to the virus that last for 3 months.
The presence of high levels of antibodies means that a person is immune to infection with the emerging coronavirus – whose 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 subject to peer review.
The researchers analyzed the blood tests of 113 patients infected with the Corona virus 5 weeks after recovering from their illness, and then again 3 months after their illness.
They found that people who contracted COVID-19 and were hospitalized had higher antibody levels than others, and overall antibody levels increased with the severity of COVID-19.
But for people who had COVID-19 and were not hospitalized, researchers noted that 4 symptoms are associated with persistently high levels of coronavirus antibodies, which are:
1- fever
2- Abdominal pain
3- Diarrhea
4- Decreased appetite
This means that if you develop these symptoms while you are sick, it can be a sign that you are likely to have a longer immunity to Corona.
Overcoming the pandemic
And the researchers said that permanent immunity – which is often estimated by persistent antibodies – will be necessary to overcome the Covid-19 pandemic.
In severe acute respiratory syndrome (SARS), antiviral antibodies persist in the majority of patients for at least 3 years after illness.
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 suggest that antibodies against SARS-CoV-2 can drop in the first few months, as some patients become negative.
