About Coronaviruses

Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). A novel coronavirus (nCoV) is a new strain that has not been previously identified in humans.

The new coronavirus, 2019-nCOV or COVID-19, is a respiratory virus that spreads primarily from person to person through small droplets from the nose or mouth, which are expelled when a person with COVID-19 coughs, sneezes, or speaks. These droplets are relatively heavy, do not travel far and quickly sink to the ground. People can catch COVID-19 if they breathe in these droplets from a person infected with the virus.

Transmission

Coronaviruses are zoonotic, meaning they are transmitted between animals and people. Detailed investigations found that SARS-CoV was transmitted from civet cats to humans and MERS-CoV from dromedary camels to humans. Several known coronaviruses are circulating in animals that have not yet infected humans.

Common signs

Common signs of infection include respiratory symptoms, fever, cough, shortness of breath and breathing difficulties. In more severe cases, infection can cause pneumonia, severe acute respiratory syndrome, kidney failure and even death.

Prevention

Standard recommendations to prevent infection spread include regular hand washing, covering mouth and nose when coughing and sneezing, thoroughly cooking meat and eggs. Avoid close contact with anyone showing symptoms of respiratory illness such as coughing and sneezing.

What ��鶹��Ʒ does

The Organization supports countries in surveillance, prevention, and preparedness for control of pandemic and epidemic-prone diseases through the development of evidence-based strategies to predict, prevent, detect, and respond.

It also ensures regional surveillance related to these infectious threats.

Main lines of action

Pandemic and epidemic-prone diseases: influenza, MERS, hemorrhagic fevers and hantaviruses, yellow fever and emerging arboviruses, plague, cholera and epidemic-prone diarrheal diseases, leptospirosis, meningococcal disease.

Networks of experts and interventions for surveillance and response: epidemiology and modeling, laboratory, clinical management, and infection prevention and control.
