Ongororo dzakaratidza kuti vafambi vendege, chitima, mabhazi kana mota vanogara vakagara kwenguva inopfuura maawa mana vari panjodzi huru yekuva ne venous thromboembolism nekuita kuti ropa remutsinga rimire, zvichiita kuti ropa riungane mutsinga. Pamusoro pezvo, vafambi vanofamba nendege kakawanda munguva pfupi vari panjodzi huru, nekuti njodzi ye venous thromboembolism haiperi zvachose mushure mekupera kwerwendo, asi inoramba yakakwira kwemavhiki mana.

Mushumo unoratidza kuti kune zvimwe zvinhu zvinogona kuwedzera njodzi ye venous thromboembolism panguva yekufamba, zvinosanganisira kufuta, kureba kwakanyanya kana kuderera (pamusoro pe 1.9m kana pasi pe 1.6m), kushandiswa kwemishonga yekudzivirira pamuviri uye chirwere cheropa chenhaka.

Nyanzvi dzinoti kufamba-famba kwetsoka kumusoro nekudzika kunogona kurovedza tsandanyama dzetsoka uye kukurudzira kufamba kweropa mutsinga dzetsandanyama dzetsoka, nokudaro zvichideredza kumira kweropa. Pamusoro pezvo, vanhu vanofanira kudzivisa kupfeka mbatya dzakasimba pavanenge vachifamba, sezvo mbatya dzakadaro dzinogona kukonzera kumira kweropa.

Muna 2000, kufa kwemukadzi wechidiki wekuBritain kubva mundege refu muAustralia nekuda kwechirwere chemapapu chakakwezva vezvenhau neveruzhinji kunjodzi yekubuda ropa muropa mukufamba kwenguva refu. WHO yakatanga chirongwa cheWHO Global Travel Hazards Project muna 2001, nechinangwa chekutanga chiri chekusimbisa kana kufamba kuchiwedzera njodzi yekubuda ropa muropa mutsinga uye kuona kuoma kwenjodzi; mushure mekunge mari yakakwana yawanikwa, chidzidzo chechipiri cheA chichatanga nechinangwa chekuona matanho ekudzivirira anoshanda.

Sekureva kweWHO, zviratidzo zviviri zvinonyanya kuoneka zve venous thromboembolism ndeizvi: deep vein thrombosis uye pulmonary embolism. Deep vein thrombosis chirwere chinoitika apo ropa rinogwamba kana kuti thrombus inoumbwa mutsinga yakadzika, kazhinji mugumbo rezasi. Zviratidzo zve deep vein thrombosis zvinonyanya kurwadza, kupfava, uye kuzvimba munzvimbo yakakanganiswa.

Kuputika kweropa mutsinga dzemuviri (deep vein thrombosis) kunoitika kana ropa rakagwamba mutsinga dzemuviri dziri pasi (kubva pa deep vein thrombosis) rikatyoka rofamba nemuviri kuenda kumapapu, uko rinoisa ropa rovharira. Izvi zvinonzi pulmonary embolism. Zviratidzo zvinosanganisira kurwadziwa pachipfuva uye kuoma kufema.

WHO yakati thromboembolism yetsinga inogona kuonekwa kuburikidza nekuongororwa nachiremba uye kurapwa, asi kana ikasarapwa, inogona kuisa hupenyu panjodzi.
