Frequently Asked Questions
What is the incubation time of COVID-19?
The incubation time, duration between exposure to the virus and the manifestation of the first symptoms, is evaluated between 3 and 5 days in the majority of cases, but can last in extreme cases of 12 and 14 days.
What is the Symptoms and course?
Manifestations of coronavirus appear less than 24 hours after infection. Most commonly, it causes mild to moderate respiratory illnesses like the common cold with symptoms such as:
a general feeling of discomfort
new covid-19 symptoms include loss of taste and smell.
More seriously – as we have seen with the new coronavirus – it can cause respiratory diseases of the lower tract such as pneumonia or bronchitis, especially in people with cardiopulmonary disease, in those with an immune system weakened and the elderly.
There is a vaccine against Coronavirus?
There is currently no vaccine available to protect against infection with a human coronavirus. However, scientists at the Institut Pasteur are multiplying initiatives to find a vaccine against the coronavirus. They have managed to isolate and culture strains of the new virus 2019 and hope to develop a vaccine within a year and a half, said researchers from the National Reference Center for Respiratory Viruses in a press release dated January 30, 2020. ” Researchers at the Pasteur Institute now have the virus that causes this infection. This viral isolation opens the way to new diagnostic, therapeutic and prophylactic approaches. ”
Does COVID-19 Kill?
The mortality rate is relatively high for SARS and MERS-CoV, with respectively close to 10 to 15% and more than 36% of deaths of people affected. The most sensitive people are those over 65, those suffering from respiratory pathologies and immunocompromised. For Sars-CoV-2, the fatality rate is 2 out of 100 patients in France.
How to prevent?
To reduce your risk of infection with a coronavirus, it is advisable to:
wash your hands regularly with soap and water for at least 20 seconds (without forgetting very practical hydro-alcoholic solutions when you cannot wash your hands),
avoid touching your eyes, nose or mouth when your hands are not washed,
avoid contact with sick people,
wear a mask.
Types of coronavirus: SARS, MERS, Sars-CoV-2 …
SARS-CoV (the beta-coronavirus that causes Severe Acute Respiratory Syndrome, or SARS, identified in China in 2002).
MERS-CoV (the beta coronavirus that causes Middle East respiratory syndrome, or MERS discovered in 2012 in Saudi Arabia).
Sars-SoV-2 identified in China in December 2019. This coronavirus has many similarities to that of SARS (animal origin, genetically identical to 80%, responsible for pulmonary infections) but also notable differences for scientists in terms of its contagion. It is contagious from the onset of symptoms or sometimes in the absence of symptoms, while SARS was so a few days after the first symptoms. There are also benign and asymptomatic forms of Covid-19, while SARS only caused severe forms.
