According to the World Health Organization (WHO), the most common symptoms of COVID-19 or coronavirus 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 get COVID-19 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.
If you think you have the relevant symptoms — a fever of 37.5 degrees Celsius (99.5 degrees Fahrenheit), fatigue and trouble breathing — for four days, call your local public health center or a coronavirus hotline, according to the health ministry.
A doctor will determine whether a patient receives a PCR test. Those who test positive are admitted to a hospital with a specialist infectious disease ward. Self-referrals are not accepted.

Wash your hands regularly with soap and antibacterial agents before touching your face or eating, and after coming in contact with animals and public spaces like restaurants and public transportation.
The virus is spread via respiratory droplets—easily transmitted through coughing and sneezing. Obviously, you want to avoid contact with sick people and try to maintain at least a one-meter distance between yourself and infected persons. Riding the train during morning and evening rush hours in major cities like Tokyo may increase your chance of exposure.
This is important in public spaces with high turnover rates, such as fast-food restaurants.
