Five situations that increase the risk of infection.
Through analysis of prior outbreaks, behaviors and circumstances associated with a high risk of infection have been identified. It has been found that the spread of COVID-19 infection spreads primarily through clusters. Based on the findings from cluster analysis, the Subcommittee on Novel Coronavirus Disease Control has compiled a list of five situations that increase the risk of infection.
Situation 1Social gatherings with drinking alcohol
- Drinking alcohol improves mood and at the same time decreases attention. In addition, hearing is dulled and it leads to speaking in a louder voice.
- The risk of infection increases when large numbers of people are in a small space for a long time.
- In addition, sharing glasses and chopsticks increases the risk of infection.
Situation 2Long feasts in large groups
- Long-term meals, dinner receptions, and drinking alcohol at night increases the risk of infection compared to a short meal.
- The risk of infection is increased by eating and drinking in a large group of people, for example, 5 or more people, because in groups you have to talk louder and droplets of saliva spread more often.
Situation 3Conversation without a mask
- Talking at close range without a mask increases the risk of airborne or micro-droplet infection.
- Cases of infection without masks were observed during gatherings at daytime karaoke.
- Please be careful when traveling by car or bus.
Situation 4Living together in a small limited space
- Living together in a small limited space increases the risk of infection because the enclosed space is shared by several people for a long time.
- There have been reports of suspected infections in common areas such as dormitory rooms and bathrooms.
Situation 5Switching locations
- When you move to another location, such as when you take a break in a workplace, the risk of infection may increase due to the feeling of relaxation and changes of the environment.
- Suspected cases of infection were identified in break rooms, smoking areas, and changing rooms.
