Preventing COVID-19 (novel coronavirus) and stopping its spread

Preventing COVID-19 (novel coronavirus) and stopping its spread

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.

What should I do in my everyday life?

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.

Use the COVID-19 Contact-Confirming Application (COCOA) to learn the possibility that you have had contact with someone who has tested positive.

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.

Please make sure the following when going for a medical examination.
Unless directed by a doctor, please refrain from visiting more than one medical institution, because there have been cases where doing so has caused the spread of infection.

When visiting a medical institution, please wear a mask, wash your hands and fingers thoroughly, and follow proper cough etiquette*.

* When coughing or sneezing, use a mask, tissue paper, handkerchief, sleeve or the inside of your elbow to cover your mouth and nose.
