In general, neither hair washing nor disinfection is necessary when back home from outside. Current research has found that the virus is sensitive to UV light and heat. There is very little chance that infectious droplets with a high concentration of virus could stick to the hair. So just keep your hair clean as usual.

一般情況下，公眾外出回家后不需要特意洗頭或消毒。目前研究顯示，病毒對外部環境中的紫外線和熱比較敏感。在室外，頭發粘到高濃度同時有活病毒的飛沫可能性非常低，保持頭發日常清潔即可。
