COVID-19 is an infectious disease caused by a coronavirus called SARS-CoV-2. It mainly causes symptoms such as fever and/or cough. In general, it is spread through droplet and contact transmission. It has been pointed out that it may spread before symptoms appear. It is therefore important to habitually follow the general strategies for preventing infectious diseases, such as social distancing and wearing a mask when in public.

In particular, keep the following in mind.

・Refrain from going out
・Wash your hands
・Follow cough etiquette
・Ensure ventilation
・Avoid closed spaces
・Avoid crowded places
・Avoid close-contact settings

The basic strategies for preventing infectious diseases, including COVID-19, are hand washing and cough etiquette, which includes wearing a mask. The main commonalities of outbreaks are: (1) poor ventilation, (2) a space where people spend time gathered closely together, and (3) a place where unspecified large numbers of people are likely to come into contact with each other. These are the three Cs (Closed spaces, Crowded places, and Close-contact settings). Avoid gathering in groups in spaces where ventilation is poor and people spend time close together. Aim to completely avoid the three Cs.
