Corona virus can cause illnesses such as the common cold, severe acute respiratory syndrome (SARS) and the Middle East respiratory syndrome (MERS).

The infection is spread from one person to others via respiratory droplets produced from the airways, often during coughing or sneezing.

Corona virus Signs and Symptoms:-

COVID-19 may appear two to 14 days after exposure and can include

Those infected may either be asymptomatic or develop symptoms including fever, cough, and shortness of breath. Diarrhea or upper respiratory symptoms (e.g. sneezing, runny nose, sore throat) are less frequent. Cases can progress to pneumonia, multi-organ failure, and death in the most vulnerable.

The incubation period ranges from 1 to 14 days with an estimated median incubation period of 5 to 6 days according to the World Health Organization (WHO).

Another study of 1,099 Chinese patients found that CT scans showed ground-glass opacities in 56% of patients, but 18% had no radiological findings. 5% of patients were admitted to intensive care units, 2.3% needed mechanical support of ventilation, and 1.4% died. Bilateral and peripheral ground-glass opacities are the most typical CT findings, according to researcher Bernheim et al. Consolidation, linear opacities, reverse halo sign are other radiological findings. Initially, the lesions are located to one lung, but as the disease progress, indications manifest to both lungs in 88% of patients. Children seem to handle the disease better than adults as the symptoms are usually milder, but sufficient evidence is still lacking.

Protective measures against corona virus:-

Stay aware of the latest information on the COVID-19 outbreak, available on the WHO website and through your national and local public health authority. COVID-19 is still affecting most people in China with some outbreaks in other countries. Most people who become infected experience mild illness and recover, but it can be more severe for others. Take care of your health and protect others by doing the following:

1. Wash your hands often with soap and water, or use an alcohol-based hand sanitizer.

2. Cover your mouth and nose with your elbow or tissue when you cough or sneeze.

3. Avoid touching your eyes, nose, and mouth if your hands aren’t clean.
