What are the symptoms of Covid-19?


This is why it is essential to avoid touching your eyes, nose or mouth (which are entry points posvirus in your body) with dirty hands. So-called "barrier" measures are therefore essential to limit the impact of the virus: wash your hands frequently with soap or hydroalcoholic gel, sneeze or cough in your elbow, use single-use tissues, do not shake hands , don't kiss them to say hello…


What are the symptoms of Covid-19?

The most common symptoms of the virus are fever and a dry cough. Some people may also experience body aches, headaches, tightness or shortness of breath. These symptoms suggest an acute respiratory infection or radiologically detectable lung abnormalities. In more severe cases, the infection can cause "respiratory distress, acute renal failure, or even multiple organ failure that can lead to death," said the Ministry of Health.

As a reminder: the disease remains mild in 80% of cases; it is severe in around 15% of cases and critical in 5% of cases. Researchers estimate that the overall mortality rate from the virus is around 2 to 4%, with disparities depending on the country. Or a rate higher than that of the influenza virus which kills one person in a thousand (0.1%). Some patients also have an asymptomatic form of the virus: they carry the virus, without declaring the symptoms, but they are contagious and can transmit it.

Given that the symptoms of Covid-19 can be confused with those of influenza, the only way to confirm the diagnosis is to perform a biological test by nasopharyngeal sampling. At stage 3 of the epidemic in France, this test is no longer systematic and may be available in the city laboratory (no longer only in referral health establishments).

Is there a vaccine for Covid-19?
Vaccines against pneumonia, such as the pneumococcal vaccine and the Haemophilus influenzae type B (Hib) vaccine, unfortunately do not protect against the coronavirus. The Covid-19 is so new and specific that it is necessary to develop a vaccine of its own. Dozens of clinical trials are currently underway. According to a researcher from the Institut Pasteur on RTL, prototypes have been tested on mice since March 11.

Normally, the development cycle of a vaccine takes several years. However, in the current context, companies are accelerating the pace of their research and shortening development times.

Are there people at risk of developing a more severe form of the disease?

Available information suggests that the virus can cause symptoms similar to those of moderate flu, but also more severe symptoms. As with many infectious diseases, people with pre-existing chronic diseases (hypertension, cardiovascular disease, diabetes, liver disease, respiratory disease ...) seem more likely to develop severe forms, as are the elderly and immunocompromised .

Patients with chronic obstructive pulmonary disease (COPD) are particularly vulnerable. A study published in the journal Jama at the end of February also indicates that men could be more affected by the virus.

Children under the age of fifteen are unlikely to trigger a severe form of coronavirus. As Professor Matthieu Revest, infectiologist, pointed out during an intervention at the University of Rennes 1, there was 0% death among children under 15 in a study of the first 72,000 Chinese cases . But, remember: even if they present less serious, even asymptomatic forms, they are contaminants.
