Mwasho unaoendana na homa ya Zika.

Homa ya Zika (kwa Kiingereza Zika fever) ni ugonjwa unaosababishwa na virusi vya Zika, jamii ya jenasi Flavivirus.

Dalili zake zinafanana na zile za virusi vingine vya jenasi hiyo, kama vile Homa ya dengue au alfavirusi chikungunya, lakini ni afadhali kidogo na kwa kawaida zinadumu siku 4 hadi 7 tu. Asilimia kubwa (60–80%) hazina dalili za pekee.[1]

Wagonjwa wenye dalili wana homa kidogo, conjunctivitis, maumivu ya muda kwenye jointi (hasa zile ndogo za mikononi na miguuni) na mwasho ambao mara nyingi unaanza usoni na kuenea katika mwili wote.

Pamoja na kwamba ugonjwa huo hauna dalili za kutisha, wataalamu wa afya wanauhusisha na tatizo la microcephaly kwa mimba za wanawake wanaopatwa, kama ilivyoonyeshwa na mlipuko wa mwaka 2015 nchini Brazil ambao mwaka 2016 unazidi kuenea barani Amerika.[2][3][4][5][6][7][8][9][10][11][12]

Katika mlipuko uliotokea huko Polinesia ya Kifaransa kulikuwa na ongezeko la Guillain–Barré syndrome.[1][13]

Ugonjwa unaenezwa na mbu wa jenasi Aedes, hasa Aedes aegypti, lakini pia A. africanus, A. coargenteus, A. luteocephala,[14] A. vitattus na A. furcifer. During the 2007 outbreak on Yap Island in the South Pacific, Aedes hensilli was the vector, while Aedes polynesiensis spread the virus in French Polynesia in 2013.

Pia zimethibitishwa habari za kwamba ngono inaweza kusababisha ambukizo, na vilevile uchangiaji wa damu na uzazi (wakati wa kujifungua).[15]

Mnamo Desemba 2016, mhusika mkuu wa udhibiti wa maradhi ya namna hii nchini Tanzania aliripoti kuhusu idadi ya wakazi ambao walipimwa na kuonekana kupatwa na homa ya Zika pamoja na idadi ya watoto wachanga waliozaliwa na ulemavu kutokana na homa hiyo. Mara moja rais John Magufuli alimuengua.
