M’zaka zaposachedwapa, chifukwa cha kuzama kwa kusinthanitsa ndi mgwirizano wa mayiko, kusinthana pakati pa mayiko kwachitika kawirikawiri, ndipo chiwerengero cha apaulendo chikuwonjezeka chaka ndi chaka. Panthawi imodzimodziyo, chifukwa cha zinthu monga kusamuka kwa mbalame zosamukasamuka, mwayi wa West Nile fever ku China wawonjezeka[4].
