General Zano
Bvunza chiremba. Ratidza iyi yekuchengetedza data data kuna chiremba varipo.
Kana inhare
Kana akafemerwa mukati, fambisa munhu mumhepo nyowani. Kana zvisiri kufema, ipa kufema kufema. Bvunza chiremba.
Kana iri yeganda kusangana
Geza nesipo uye mvura yakawanda. Bvunza chiremba.
Kana iri yekubata neziso
Fungidzira maziso nemvura sekungwarira.
Kana kumedzwa
Usambofa wakapa chero chinhu nemuromo kune munhu asingazivi. Geza muromo nemvura. Bvunza chiremba.
1. Inhalation uye ganda kusangana: kusangana neGVL kunogona kukonzera ganda uye ziso kutsamwisa. Inhalation of vaphare inogona zvakare kukonzera kutsamwisa kutsamwisa. Zvinokurudzirwa kushandisa zvakakodzera zvekudzivirira midziyo (ppe), senge magurovhosi uye gogo, paunenge uchibata GVL.
2. Kupa: Kunyangwe GVL isingaratidzwi zvakanyanya zvine chepfu, kumhanyisa mari yakakura kunogona kukonzera kusagadzikana kwegastroint uye mamwe matambudziko ehutano.
3.. Nekudaro, zvinogara zvakakosha kuti utarise kune yekuchengetedza data pepa (SDS) uye yemuno mitemo yekubata chaiyo kubata uye kufumura mirayiridzo.
