Omicron, how many days do you stay positive? And how long can it be infected? The times (and the course)

by admin

How long does the Sars Cov-2 virus infection last? There is no “fixed” course, the same for everyone. Some research has noted a median period of 15 days of detectability of the viral genome through a swab test. But for many, the positivity can last for weeks or even months. There are many changing factors to consider, starting with the severity of the disease and what can contribute to making it milder: the vaccine, for example. Hence, the positivity will usually last as severe has the course been.

Studies on the duration of the infection

A study conducted this summer on the Israeli military (and published in the Journal of Medical Virology) noted that the median time to elimination of Sars Cov-2 it is about three weeks in young adults who have mild symptoms.

A recent work that analyzed 32 scientific articles that saw the study of 69,093 cases, instead noted how the duration average length of stay in intensive care was 9 days.

But how long are you infectious? A US study published in Clinical Infectious Diseases showed that people are most contagious around the time of onset of symptoms with infectivity rapidly decreasing to almost zero after about 10 days in mild to moderately ill patients and 15 days in critically ill and immunocompromised patients. The longest interval so far associated with replication competent virus is 20 days from the onset of symptoms. And a research in the Journal of Infection specifies how it is “highly unlikely», Which patients Covid-19 mild and moderate are infectious after the 10th day of illness.

What are the most frequent symptoms

With the variante Omicron more and more studies have shown that the virus does not touch the lower respiratory tract as the others did. The most frequent effects are cough, joint and muscle pain, fever, lack of taste and smell. In the most serious cases, however, respiratory problems, loss of concentration, dizziness, pneumonia. Some of these symptoms can have more or less lasting effects. Covid-19 is a systemic disease: it mainly affects the respiratory system but can also damage other organs such as hearts, kidneys and brain.

And in the children? Clinical symptoms experienced by children are generally similar to those in adults, but the disease is milder than in adults and the severity of symptoms varies with age. Many infected remain asymptomatic. But instead they would suffer from Mis-C, the multisystem inflammatory syndrome that can affect patients.
