What is Coronavirus? How to Save From This?

What is Coronavirus?

What is Coronavirus? Coronavirus are a family of different viruses that can infect both humans and animals.

Its means that “crown virus” comes from the fact that they all have a crown shaped appearance under a microscope.

Corona viruses were first identified in humans in the 1960s. These are viruses that cause new diseases, i.e. new infections caused by virus Human coronary viruses mainly cause deadly respiratory infections. It can also be accompanied by indigestion such as gastroenteritis.

Incubation period:

The incubation period, the duration between exposure to the virus and the appearance of the first symptoms, is assessed in most cases between 3 and 5 days, but in extreme cases can range from 12 to 14 days.

Types of corona viruses:

SARS, Middle East Respiratory Syndrome, SARS-CoV-2…

There are four main subgroups of coronaviruses, alpha, beta, gamma, and delta. Seven different forms, including four common (less dangerous than others):

229E (Alpha Coronary Virus)

NL63 (Alpha Coronary Virus)



Three of them are more dangerous:

SARS-COV (beta coronary virus that causes severe acute respiratory syndrome (SARS) identified in China in 2002.

MERS-COV (beta coronavirus that causes respiratory syndrome in the Middle East, or MERS-COV, detected in Saudi Arabia in 2012).

Corona virus in 2019:

The new corona virus 2019, Covid-19 or “Sars-SoV-2” was identified in China in December 2019. This coronary virus has many similarities with that of SARS (animal origin, genetically identical to 80%, responsible for lung infections), but also noticeable differences for scientists in terms of infection. It is an inexperienced symptom or sometimes in the absence of symptoms, while SARS was so a few days after the first symptoms. There are also benign and no-bide forms of The Coved-19, while SARS causes only severe forms.

Coronavirus: Live report by region, in Ile-de-France, Brittany:

CORONAVIRUS Live – The epidemic of the coronary virus is “severe and deadly” worldwide. In Europe, Italy, Spain, France and the United Kingdom are the hardest hit countries. In France, hospitals are overcrowded, requiring the evacuation of patients from Ile-de-France and the Grande Este region to less crowded hospitals. The Prime Minister will be heard in the Assembly today. Number of cases and deaths by region, map curve and real-time development, advice on how to protect yourself and better manage detention. Information to remember from April 1.

Corona virus mutation:

Coronavirus is an RNA virus with a high mutation rate such as influenza or HIV. Wreath viruses are found in many animal species and are fairly easily transmitted from one species to another, which may lead to death. Wreath viruses can infect men.

Coronaviruses live on dry and inactive surfaces for up to 3 hours.


Wreath viruses are transmitted from person to person through close contact (e.g., touching or shaking) and through the air, coughing or sneezing. If you touch a body or surface with a virus and then touch your mouth, nose or eyes before washing your hands, the aura virus may also spread. Finally, contamination is unlikely due to fecal contact.


Coronaviruses live up to 3 hours on inactive dry surfaces and up to 6 days in wet environments. Thus, the environment can be moved manually, as confirmed by the Supreme Council of Public Health in a press release dated March 5, 2020.

Symptoms, of course:

Manifestations of the coronavirus appear less than 24 hours after infection. It often causes mild to moderate respiratory problems such as colds with symptoms such as:

  • Headaches
  • Cough
  • Sore throat,
  • Fever,
  • General discomfort
  • New symptoms of COVID-19 include loss of taste and smell.

More serious – as we have seen with the new coronary virus – can cause lower respiratory problems such as pneumonia or bronchitis, especially in people with heart and lung diseases and in people with weakened immune systems and the elderly.


The mortality rate for SARS and MERS-COV is relatively high at about 10 to 15% and more than 36% of infected deaths. The most sensitive people are those over 65 years of age with respiratory disorders and immunodeficiency. For Sars-CoV-2, the mortality rate in France is 2 out of 100 patients.


There is no specific treatment for diseases caused by human coronary viruses. Symptom treatments: Take the pain, fever medication, rest, do not come out.


There is currently no vaccine available to protect against human filovirus infection. However, scientists at the Pasteur Institute are doubling initiatives to find a vaccine against coronary virus. Researchers from the National Respiratory Reference Center said in a press release on January 30, 2020, that they have successfully isolated and implanted strains of the new virus 2019 and hope to develop a vaccine within a year and a half. “Researchers at the Pasteur Institute now have the virus that causes this infection. This virus isolation opens the way to new diagnostic and preventive treatment methods.”


To reduce the risk of coronary virus infection, it is recommended that:

  • Wash your hands regularly with soap and water for at least 20 seconds (not to mention very practical alcohol-based solutions if you can’t wash your hands).
  • Avoid touching your eyes, nose or mouth when your hands are not washed.
  • Avoid contact with patients

Wear a mask.

Corona Antivirus Mask: a template to do it yourself quickly:


Wearing a face mask that protects against viruses such as COVID 19. The lack of masks has spread manufacturing patterns. Grenoble University Hospital also offered a free educational program to do it yourself. Who should wear one? Blue Surgical Mask, Duck, FFP2 … Is it disposable, reusable and effective once it expires?
