Avoid crowded places, especially closed places with little air circulation such as conferences, shows, shopping malls, public transport and religious services.
Epuka maeneo yenye watu wengi, hasa maeneo yaliyofungwa bila hewa ya kutosha, kama vile mikutano, maonyesho, duka kuu za ununuzi, usafiri wa umma, na ibada za kidini.
