A pilot study on the efficacy of nasal rinsing during ablution in reducing acute respiratory tract infection (ARI) among male Hajj pilgrims

Nasal rinsing can be included as part of intervention methods that include vaccination and the use of a face mask. Nasal rinsing can be easily practiced by the pilgrims, since it is a Sunnah act in ablution, which is an integral element of Muslims' daily life.
