About COVID-19 infection

• COVID-19 infection (COVID-19) is a disease caused by the coronavirus called SARS-CoV-2.
• It is transmitted by inhaling particles that contain small amounts of water, called virus-containing droplets or aerosols, which are excreted from the mouth and nose of infected person during coughing, sneezing or conversation, or by direct contact with the eyes, nose and mouth of infected person.

[Main Symptoms]

• Systemic symptoms such as sore throat, cough, runny nose and nose, body laxity, fever, and muscle pain often occur.
• In mild cases, symptoms often relieve within one week after onset.
• Elderly people, those with underlying illnesses, and some people in late pregnancy are at increased risk of severe illness.
• Fundamental diseases that are at risk of severe disease include chronic obstructive pulmonary disease (COPD), chronic kidney disease, diabetes, hypertension, cardiovascular disease, obesity, and smoking.
• If you are at a high risk of severe illness or have severe symptoms, consult a medical institution.

Please take care to ensure that the individual's independent judgment is respected.

For those with a high risk of severe illness (elderly people, those with underlying diseases, pregnant women, etc.), it is effective to avoid the following situations during the epidemic season.

• A place with poor ventilation
• Congested places where there are an unspecified number of people
• Close conversation

Wearing a mask is based on individual judgment.
However, be careful in the following cases.

• If COVID-19 infection is positive, it is recommended that you refrain from going out because there is a high risk of infecting others for 5 days after onset and for about 24 hours after symptoms are relieved.
• Until 10 days have passed, wear a mask and take care not to move around.
