On an airplane, adopt the same hygiene practices as everywhere else: wash your hands frequently or use a hydro-alcoholic solution if it is not practical to leave your seat, and avoid touching your face.
Kwenye ndege, fuata tabia zile za usafi kama mahali pengine popote: nawa mikono yako mara kwa mara, au utumie kisafisha mikono chenye kileo ikiwa si rahisi kuondoka kwenye kiti chako, epuka kugusa uso wako.
