Corona virus are a large family of viruses which may cause illness in animals or humans. In humans, several corona viruses are known to cause respiratory infections ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). The most recently discovered corona virus causes corona virus disease COVID-19.
The most common symptoms of Corona virus or COVID-19 are fever, tiredness, and dry cough. Some patients may have aches and pains, nasal congestion, runny nose, sore throat or diarrhea. These symptoms are usually mild and begin gradually. Some people become infected but don’t develop any symptoms and don't feel unwell. Most people (about 80%) recover from the disease without needing special treatment. Around 1 out of every 6 people who gets Corona virus becomes seriously ill and develops difficulty breathing. Older people, and those with underlying medical problems like high blood pressure, heart problems or diabetes, are more likely to develop serious illness. People with fever, cough and difficulty breathing should seek medical attention.
The disease can spread from person to person through small droplets from the nose or mouth which are spread when a person with Corona virus coughs or exhales. These droplets land on objects and surfaces around the person. Other people then catch Corona virus by touching these objects or surfaces, then touching their eyes, nose or mouth. People can also
1) Regularly and thoroughly clean your hands with an alcohol-based hand rub or wash them with soap and water.
2) Maintain at least 1 meter (3 feet) distance between yourself and anyone who is coughing or sneezing.
3) Avoid touching eyes, nose and mouth.
4) Cover your mouth and nose with your bent elbow or tissue when you cough or sneeze.
5) Stay home if you feel unwell. If you have a fever, cough and difficulty breathing, seek medical attention and call in advance. Follow the directions of your local health authority.
While we are still learning about how Corona virus affects people, older persons and persons with pre-existing medical conditions (such as high blood pressure, heart disease, lung disease, cancer or diabetes) appear to develop serious illness more often than others.
The “incubation period” means the time between catching the virus and beginning to have symptoms of the disease. Most estimates of the incubation period for Corona virus range from 1-14 days, most commonly around five days. These estimates will be updated as more data become available.
It is not certain how long the virus that causes Corona virus survives on surfaces, but it seems to behave like other corona viruses. Studies suggest that corona viruses (including preliminary information on the v virus) may persist on surfaces for a few hours or up to several days. This may vary under different conditions (e.g. type of surface, temperature or humidity of the environment).
If you think a surface may be infected, clean it with simple disinfectant to kill the virus and protect yourself and others. Clean your hands with an alcohol-based hand rub or wash them with soap and water. Avoid touching your eyes, mouth, or nose.
