Coronaviruses are a group of viruses that can lead to disease in animals or humans. It is known that respiratory infections ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS) can be caused by several coronaviruses in humans.1
The coronavirus disease 2019 (COVID-19) is an infectious spreading disease originating from Wuhan, China in December 2019 which is currently having a huge impact on health and economy worldwide.2,3 The pathogen of the disease, SARS coronavirus 2 virus (SARS-CoV-2), is a newly discovered coronavirus strain that can make people sick and cause various symptoms in the body.
People may experience symptoms such as fever, dry cough, tiredness, and some people may possess different symptoms, including aches and pains, nasal congestion, runny nose, sore throat, diarrhea, headache, loss of smell and taste, and shortness of breath. Usually, these symptoms are not severe, and people develop them gradually, whereas it is possible that some individuals get the disease without showing any symptoms. Most patients (about 80%) beat the disease without any special treatment. Difficulty in breathing and the risk of getting seriously sick was shown in around one out of every six people. Older people and those who have other diseases are at higher risk to become more ill compared to people without any underlying medical conditions.1,2
People can get infected with the virus if they are in contact with already infected people. The disease can be transmitted to another healthy person through small droplets from the nose or mouth of an infected person who is coughing or exhaling. It is also possible that the infectious disease can be transmitted by touching various surfaces and objects. Then the virus enters the body and reaches the cells which can lead to the infection.1,2
