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
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.
COCOA is an app for checking contact with COVID-19. With user consent, the app uses your smartphone’s short-range communication function (Bluetooth) and will notify you of potential contact with someone who has tested positive for COVID-19 while ensuring each user’s privacy. Users can receive support, such as testing from a public health center, sooner, by knowing that they might have been in contact with someone who has tested positive. The more users, the more effective it will be in preventing the spread of infection. Search for “COVID COCOA” in the App Store or Google Play and install the app today.
If you have cold symptoms such as fever, do not go to school or work, refrain from going out, and measure and record your body temperature every day.
Contact an appropriate call center according to the purpose of your inquiry, location, and languages available.
