Coronavirus (COV) is a large family of viruses that cause common cold-to-severe diseases such as Middle East Respiratory Tract Syndrome (MERS-CoV).
Coronaviruses are zoonotic, which means that they are transmitted between animals and people. Detailed investigation found that SARS-CoV was transferred from kvet cats to humans and MERS-CoV from dromedary camels to humans. Many known coronaviruses are roaming in animals that have not yet infected humans. Common signs of infection include respiratory symptoms, fever, cough, shortness of breath, and difficulty breathing. In more severe cases, an infection can lead to pneumonia, severe acute respiratory syndrome, kidney failure, and even death.
Standard recommendations to prevent infection include washing hands regularly, covering the mouth and nose when coughing and sneezing, and thoroughly cooking the meat and eggs. Avoid close contact with those who show respiratory symptoms such as cough and sneezing.
It is a member of the coronovirus family that has never appeared before. Like other coronaviruses, it came from animals. Many of the initially infected people either worked or shopped frequently at the Huanan Seafood Wholesale Market in the Chinese city center, which also sold life and newly slaughtered animals.
New and disturbing viruses usually originate in animal hosts. Ebola and flu are other examples, and acute respiratory syndrome (SARS) and Middle Eastern respiratory syndrome (MERS) are both caused by animal-derived coronaviruses. In 2002, Saras spread uncontrollably to about 37 countries, causing worldwide panic, infected more than 8,000 people and killed more than 750 people. MERS goes from human to human, but is even more deadly, with 35% of the approximately 2,500 people infected.
