Ukuqina Kwamanzi: Izimpawu, Izimbangela, Nokwelashwa

Ukuqina kwamanzi kuyisikhumba esingathandeki kodwa esicasulayo esingase sibe khona ngemva kokubhukuda ezihlahleni, emachibini, noma kwamanye amanzi emvelo. Nakuba amaqhubu acasulayo angase abonakale eyingozi ekuqaleni, lesi simo singesikhashana futhi sizozisula ngokwalo ezinsukwini ezimbalwa kuya kwesonto.

Cabanga ngakho njengendlela yesikhumba sakho yokusabela eziparasitic ezincane ezazilokhu zihloselwe izinyoni nezimpukane, hhayi abantu. Uma lezi zidalwa ezincane zithinta isikhumba sakho esikhundleni sezinhloko zazo ezilindelekile, zibangela ukusabela okusheshayo komzimba okubonakala njengezindawo ezibomvu nezincasulayo.

Kuyini ukuqina kwamanzi?

Ukuqina kwamanzi kuyisimo sesikhumba esibangelwa yi-parasites encane ebizwa nge-cercariae ehlala ezindaweni zamanzi amnandi. Lezi zidalwa ezincane zifuna izinyoni noma izilwane ezithile njengezinhloko zazo, kodwa ngezinye izikhathi zizama ukungena esikhuneni somuntu.

Uma i-cercariae ithinta isikhumba sakho, ayikwazi ukuphila lapho isikhathi eside njengoba abantu abayinhloko yayo yemvelo. Noma kunjalo, uhlelo lwakho lokulwa nezifo luyabona njengabaphangi futhi lwenza ukusabela kokuvuvukala. Lokhu kusabela yikho okubangela amaqhubu abomvu acasulayo.

Igama lezokwelapha lalesi simo yi-cercarial dermatitis, kodwa abantu abaningi bayibiza ngokuthi ukuqina kwamanzi. Kuyinto ehlukile kunamanye amaphutha esikhumba ahlobene nokubhukuda futhi ayinazinkinga zezempilo ezinkulu.

Ziyini izimpawu zokuqina kwamanzi?

Isinyathelo sokuqala ongase usiqaphele yisimo sokuthimfula noma ukushisa esikhuneni sakho ngokushesha nje uma usushiye amanzi. Lokhu kuzwakala okuqala kuvame ukuvela ngemizuzu embalwa kuya emahoreni okubhukuda futhi kubonisa ukuthi i-parasites ithinte isikhumba sakho.

Njengoba uhlelo lwakho lokulwa nezifo lusabela kulezi zivakashi ezingafuneki, uzoqala ukubona izimpawu ezicacile zokuqina kwamanzi:

• Amaqhubu amancane, abomvu afana namaqhubu ezinambuzane
• Ukucaphuna okukhulu okuvame ukuba sibi ebusuku
• Ama-welts aphakanyisiwe noma ama-blisters ezindaweni ezinzima
• Ukusha noma ukushaywa kwezinzwa ezizungezile izindawo ezithintekile
• Isikumba esizizwa sinzima noma sibuhlungu uma sithintwa

Yini ebangela ukuqina kwamanzi?

Ukuqina kwamanzi kwenzeka uma i-parasites encane ebizwa nge-schistosome cercariae iphazamisa isikhumba sakho njengoba ibingumnikazi wayo. Lezi zidalwa ezincane zine-cycle yokuphila eyingozi evame ukubandakanya izinhlobo ezithile ze-snails nezinyoni zamanzi noma izilwane.

Nanku ukuthi lezi parasites zivame ukuphela kanjani emanzini lapho ubhukuda khona:

1. Izinyoni noma izilwane ezine-parasites zikhulula amaqanda e-parasite ngokukhishwa kwazo emanzini
2. La maqanda aphuma futhi athole indlela yawo e-snails zamanzi amnandi
3. Ngaphakathi kwe-snails, i-parasites ikhula ibe yi-cercariae
4. I-cercariae evuthiwe ishiya i-snails futhi ibhukude emanzini, ifuna umnikazi wayo olandelayo
5. Uma ungena emanzini, lezi parasites eziphazamisayo zizama ukungena esikhuneni sakho

I-parasites ayikwazi ukuqedela i-cycle yayo yokuphila kubantu, ngakho-ke ifa ngokushesha ngemva kokuxhumana. Noma kunjalo, uhlelo lwakho lokulwa nezifo seluye lwathinteka ukuba khona kwalo, okubangela ukusabela kokuvuvukala okuhlangenwe nakho njengokuqina kwamanzi.

Amanzi afudumele, ajulile anezinhlanzi eziningi avame ukugcina i-snails nezinyoni eziningi, okwenza kube izindawo ezivame ukubhekana nalezi parasites. Izindawo ezithulile, ezivikelwe njenge-coves noma imigqa yasemgwaqeni zivame ukuba nokuhlanganiswa okuphezulu kwe-cercariae kunamanzi avulekile, ajulile.

Kufanele ubone nini udokotela ngokuqina kwamanzi?

Izimo eziningi zokuqina kwamanzi zibumnene futhi ziyaphela ngokwazo ngaphandle kokwelashwa kwezokwelapha. Noma kunjalo, kunezimo ezithile lapho kufanele ucabangele ukuthintana nodokotela wezempilo ukuze uthole isiqondiso.

Kufanele uthinte udokotela wakho uma uqaphela izimpawu zokutheleleka kwe-bacterial ekuqaleni kwe-rash. Lokhu kungenzeka uma ukucaphuna okukhulu kuphazamisa isikhumba futhi kuvumela i-bacteria ukuba ingene.

Qaphela lezi zimpawu zezeshwa ezibonisa ukuthi ungase udinga ukunakekelwa kwezokwelapha:

• I-pus noma ukukhishwa okupinkiwe ezingxenyeni ezithintekile
