Dolzarbligi. Qizamiq — samarali vaksina mavjudligiga qaramay, jahon
miqyosida qayta ko'tarilayotgan yuqumli kasalliklardan biri hisoblanadi. Jahon
sog'liqni saqlash tashkiloti (JSST) ma'lumotlariga ko'ra, 2023-yilda qizamiq bilan
kasallanish 2022-yilga nisbatan 20% ga oshgan bo'lib, xususan Yaqin Sharq, Afrika va
Janubi-sharqiy Osiyo mintaqalarida o'tkir epidemiyalar qayd etildi. Buyuk Britaniya
2026-yilda qizamiq eliminatsiya maqomini yo'qotdi — bu vaksinatsiya qamrovining
pasayishi bilan to'g'ridan-to'g'ri bog'liq holat (Venkatesan, 2026). Podacha immunitetni
saqlab qolish uchun zarur bo'lgan 95% vaksinatsiya qamrovi chegarasiga ko'plab
mamlakatlar hali erisha olmayapti; bu esa epidemiologik vaziyatni beqarorlashtiruvchi
asosiy omil sifatida ilmiy hamjamiyat diqqatini jalb etmoqda (Mwale, 2026; Mercado
et al., 2026).
