Europa \u0219i America de Nord ar putea deveni noi zone de risc pentru virusul chikungunya, pe m\u0103sur\u0103 ce schimb\u0103rile climatice \u0219i temperaturile tot mai ridicate favorizeaz\u0103 extinderea habitatelor \u021b\u00e2n\u021barilor, arat\u0103 un nou studiu publicat \u00een revista Frontiers in Cellular and Infection Microbiology<\/a>.<\/p>\n

Cercetarea, realizat\u0103 de oameni de \u0219tiin\u021b\u0103 din China, arat\u0103 c\u0103 139 de \u021b\u0103ri \u0219i regiuni sunt deja considerate zone de risc pentru aceast\u0103 boal\u0103 viral\u0103 transmis\u0103 de \u021b\u00e2n\u021bari.<\/p>\n

Asta reprezint\u0103 peste 21% din suprafa\u021ba terestr\u0103 a lumii.<\/p>\n

\u201eDar ar\u0103t\u0103m c\u0103, conform modelelor de schimb\u0103ri climatice, virusul se va extinde \u00een continuare spre nord \u00een regiunile temperate, \u00een special nord-estul Americii de Nord, Europa Central\u0103 \u0219i Asia de Est\u201d, a declarat Dr. Ye Xu, coautor al studiului.<\/p>\n

Cum modific\u0103 clima comportamentul \u021b\u00e2n\u021barilor?<\/h2>\n

Cercet\u0103torii explic\u0103 faptul c\u0103 virusul chikungunya era transmis \u00een principal de \u021b\u00e2n\u021barul Aedes aegypti, prezent \u00een zonele tropicale \u0219i \u00een apropierea a\u0219ez\u0103rilor umane.<\/p>\n

\u00cen ultimii ani, \u00eens\u0103, schimb\u0103rile climatice \u0219i mobilitatea popula\u021biei au favorizat r\u0103sp\u00e2ndirea altor specii de \u021b\u00e2n\u021bari purt\u0103tori ai virusului.<\/p>\n

\u00cen timpul epidemiei din Oceanul Indian din 2005-2006, speciali\u0219tii au identificat o muta\u021bie care a f\u0103cut virusul mai adaptabil la \u021b\u00e2n\u021barul tigru asiatic.<\/p>\n

\u201eDeoarece acest \u021b\u00e2n\u021bar poate tolera condi\u021bii mai reci mai bine dec\u00e2t \u021b\u00e2n\u021barul febrei galbene, \u00eenc\u0103lzirea i-ar putea permite s\u0103 se stabileasc\u0103 \u00een locuri care \u00eenainte erau prea reci\u201d, a spus Dr. Yang Wu, coautor al studiului.<\/p>\n

Potrivit cercet\u0103rii, temperaturile cuprinse \u00eentre 18 \u0219i 28 de grade Celsius accelereaz\u0103 dezvoltarea virusului \u00een interiorul \u021b\u00e2n\u021barilor de patru p\u00e2n\u0103 la cinci ori.<\/p>\n

C\u00e2t de departe se pot r\u0103sp\u00e2ndi \u021b\u00e2n\u021barii?<\/h2>\n

Studiul arat\u0103 c\u0103 transmiterea local\u0103 a chikungunya a fost raportat\u0103 deja \u00een 114 \u021b\u0103ri, iar peste trei sferturi din popula\u021bia lumii este expus\u0103 riscului.<\/p>\n

Rata mortalit\u0103\u021bii este estimat\u0103 la aproximativ 1,3 la mie.<\/p>\n

Pentru a evalua evolu\u021bia viitoare a bolii, cercet\u0103torii au analizat zeci de mii de date geo-localizate \u0219i au folosit 16 scenarii climatice elaborate de Grupul interguvernamental de exper\u021bi privind schimb\u0103rile climatice (IPCC) al ONU.<\/p>\n

Concluzia a fost c\u0103 Europa central\u0103 \u0219i de nord-est, nord-estul Americii de Nord \u0219i Asia de Est ar putea deveni principalele puncte fierbin\u021bi pentru r\u0103sp\u00e2ndirea virusului p\u00e2n\u0103 \u00een anul 2100.<\/p>\n

\u00cen prezent, virusul nu este endemic \u00een Europa sau America de Nord, iar cazurile raportate sunt asociate \u00een principal c\u0103l\u0103toriilor din zone tropicale \u0219i subtropicale.<\/p>\n

\u00cen 2025, la nivel mondial au fost raportate peste 502.000 de cazuri de chikungunya \u0219i 186 de decese \u00een 41 de \u021b\u0103ri \u0219i teritorii, potrivit Organiza\u021biei Panamericane a S\u0103n\u0103t\u0103\u021bii.<\/p>\n

\u201ePublicul nu trebuie s\u0103 intre \u00een panic\u0103, dar sistemele de s\u0103n\u0103tate ar trebui s\u0103 se preg\u0103teasc\u0103 din timp\u201d, a avertizat Dr. Xu.<\/p>\n

Printre m\u0103surile recomandate se num\u0103r\u0103 monitorizarea \u021b\u00e2n\u021barilor, preg\u0103tirea personalului medical pentru recunoa\u0219terea rapid\u0103 a virusului, cre\u0219terea m\u0103surilor de control al \u021b\u00e2n\u021barilor \u0219i elaborarea unor planuri de interven\u021bie \u00eenainte de apari\u021bia focarelor.<\/p>\n","protected":false},"excerpt":{"rendered":"
