Correct answer 3

Key pointLegionella bacteria multiply easily in circulating bathtubs, which should be disinfected with chlorine-based chemicals.

Explanation

Legionella bacteria multiply in places where warm water collects, such as circulating bathtubs and humidifiers, and people are infected by breathing in aerosols (water spray). Circulating bathtubs are disinfected with chlorine-based chemicals, and they are cleaned and the water is changed regularly.

  • 1: Disinfecting clothes with hot water is a measure against norovirus and the like. Legionnaires' disease does not spread from person to person, so this is incorrect.
  • 2: Cooking with heat is a measure against food poisoning. Food is not the main route of Legionella infection, so this is incorrect.
  • 4: Disinfecting doorknobs with sodium hypochlorite is a measure against contact infection such as norovirus, so this is incorrect.
  • 5: Humidifier water should not be left standing. It should be changed every day and the tank cleaned, so this is incorrect.
Explanation in Japanese

レジオネラ菌は循環式浴槽や加湿器など、温かい水がたまる場所で増殖し、エアロゾル(水しぶき)を吸い込んで感染する。循環式浴槽は塩素系薬剤で消毒し、定期的に清掃・換水する。

  • 1:衣類の熱湯消毒はノロウイルスなどの対策で、レジオネラ症は人から人へはうつらないので誤り。
  • 2:加熱調理は食中毒対策で、レジオネラの主な感染経路ではないので誤り。
  • 4:ドアノブの次亜塩素酸ナトリウム消毒はノロウイルスなど接触感染の対策なので誤り。
  • 5:加湿器の水はため置きせず毎日交換し、タンクを清掃するので誤り。
