Uambukizo wa chawa kichwani
Uambukizo wa chawa kichwani (pia inajulikana kama pediculosiscapitis,[1] mayai ya chawa,[2] au chawa[3]) ni maambukizi ya nywele ya kichwa na skalpu na chawa wa kichwa (Pediculus humanus capitis).[4] mwasho kutokana na kuumwa na chawa ni ya kawaida.[5] Wakati wa maambukizi ya kwanza ya mtu, mwasho inaweza kukosa kutokea hadi wiki sita.[5] Ikiwa mtu ataambukizwa tena, dalili zinaweza kuanza tena haraka.[5] Mwasho unaweza kusababisha matatizo ya kulala.[6] Kwa kawaida, hata hivyo, sio hali iliyo hatari sana.[7] Ilhali chawa inaonekana kusambaza magonjwa mengine nchini Afrika, hawaonekani kufanya hivyo barani Ulaya au Amerika Kaskazini.[4][6]

Kisababishi na utambuzi
haririChawa husamabazwa kwa kugusana moja kwa moja na nywele ya mtu aliyeambukizwa.[6] Kisababishi cha uambukizo wa chawa kichwani haihusiani na hali ya usafi.[5] Wanyama wengine, kama vile paka na mbwa, hawachangi usambazaji.[6] Chawa hula tu damu ya binadamu na wanaweza kuhisi tu kwa nywele ya binadamu.[4][5] Wakiwa wakubwa, wako na urefu wa karibu milimita 2 hadi 3.[8] Wakati hawako kwa binadamu hawawezi kuhisi zaidi ya siku tatu.[5] Binadamu anaweza pia kuambukizwa aina mbili za chawa – chawa wa mwili na chawa wa sehemu za jenitalia. Ili kufanya utambuzi, ni lazima chawa aliyehai apatikane.[5] Ukitumia kichana inaweza kusaidia kupata.[5] Makaka ya mayai yaliyowazi (inajulikana kama mayai ya chawa) hayatoshi kwa utambuzi.[5]
Matibabu
haririUwezekano wa matibabu inajumuisha: kuchana nywele kila wakati na kichana kizuri au kunyoa kichwa kabisa. Baadhi ya matibabu yajuu ya mwili ni salama pia, ikiwemo malathion, invermectin, na dimeticone.[7] Dimeticone, ambayo ni mafuta ya silicone, hupendelewa sana kwa sababu ya athari ya chini.[7] Pyrethroidkama vile permethrin yametumiwa sana; hata hivyo, yamekuwa na faida ya chini kwa sababu ya ongezeko la pingamizi.[7] Hii ni ushahidi kidogo wa dawa mbadala.[9]
Epidemiolojia, historia, jamii na utamaduni
hariri-Maambukizi ya kichwa ya chawa ni kawaida, haswa kwa watoto.[5] Barani Ulaya, wanaambukiza kati ya asilimia 1 na 20 ya vikundi tofauti ya watu.[4] Nchini Marekani, kati ya watoto milioni 6 hadi 12 wanaambukizwa kwa mwaka.[6] Hutokea mara nyingi kwa wasichana kuliko wavulana.[5] Imependekezwa kihistoria, kuwa maambukizi ya kichwa na chawa ilikuwa na manufaa, walipokuwa wanazuia dhidi ya chawa wa mwili walio hatari zaidi.[10] Maambukizi inaweza kusababisha unyanyapaa kwa watu walioambukizwa.[5]
