Coronaviruses are a large family of viruses that owe their name to the crown shape of the proteins around them. They are part of a large family of viruses, some of which infect different animals, others humans.
They are likely to be the cause of a wide range of illnesses that cause illnesses ranging from a common cold (some seasonal viruses are Coronaviruses) to more severe illnesses.
Coronaviruses can cause fatal epidemics such as:
SARS-CoV (2002-2003) appeared in 29 countries, more than 8000 people were infected and at least 774 people died (death rate 10%).
The MERS-CoV (2012-2013) appeared in 26 countries, more than 1,589 people were infected and at least 567 people died (death rate around 30%).
The new virus identified in January 2020 in China is a new Coronavirus. It has been appointed COVID-19 by the World Health Organization (WHO).
How is the disease transmitted?
The SARS-CoV, SARS-CoV-2, and MERS-CoV coronaviruses are not only transmitted from animals to humans but also from humans to humans.
With regard to Covid-19 disease, the disease is transmitted in particular by postillions (sneezing, coughing).
Contact of the hands with infected surfaces and then with the mouth, nose or eyes is also a factor in the spread of the virus.
It is therefore considered that close contact with a sick person is necessary to transmit the disease: same place of life, direct contact within a meter during a cough, sneeze or a discussion in the absence of measures protection.
Covid-19 is highly contagious: its replication rate is 2, which means that 1 case in the presence of 100 people can potentially infect 2 people.
Symptoms may appear up to 14 days after contact.
The COVID-19 symptoms.
The most common symptoms of the virus are a high fever, above 37.5 ° C,
a dry or loose cough.
Some people may also experience aches, headache, tightness or shortness of breath. These symptoms suggest an acute respiratory infection.
The sudden loss of smell and loss of taste may also presage the disease.
In more severe cases, the infection can cause respiratory distress,
acute kidney failure, or even multiple organ failure that can lead to death.
Breathing difficulties can occur after a few days of illness, even when the first
symptoms were mild.
Pending the results of more successful research, it is advisable to take
broad preventive measures:
- Wash your hands regularly with soap and water.
- In addition, wash your hands with hydro alcoholic gel very often.
- Avoid direct physical contact with sick or quarantined people.
- Wear a mask if you go to densely populated areas or to suspect areas.
- Wear gloves to avoid contact with surroundings or contaminated surfaces.
- Promptly consult a doctor in case of fever.
- Do not come into contact with objectively sick animals.
- Do not come into contact with objectively ill people.
- Avoid any contact with any animal or human.
- Do not slaughter sick animals for the purpose of consuming their meat.
- Do not eat undercooked meat or unpasteurized dairy products
- Do not consume raw foods (salads, fruits, raw vegetables) if you cannot be sure that they have been washed beforehand with decontaminated water.
