The Lagos State Commissioner for Health, Prof. Akin Abayomi, says Lagos Island has the highest number of suspected cholera cases with 106 cases out of the 350 suspected cases in the state.
Abayomi disclosed on Monday through his official X account @profakinabayomi while giving an update on the state's cholera outbreak.
According to the World Health Organisation (WHO), cholera is an acute diarrhoeal infection caused by ingestion of food or water contaminated with the bacterium Vibrio cholerae.
Cholera can cause severe acute watery diarrhea and the severe forms of the disease can kill within hours if left untreated.
Abayomi disclosed that laboratory tests have confirmed that the outbreak was due to cholera with the identified strain being highly aggressive and contagious, with potential for widespread dissemination.
Speaking on morbidity and mortality, Abayomi disclosed that 350 suspected cases of cholera were reported in 29 wards across multiple local government areas (LGAs) in the state.
According to him, there are 17 confirmed cases and 15 fatalities attributed to severe dehydration caused by delayed presentation at health facilities.
The commissioner further said that the geographical distribution of suspected cases by LGAs revealed that Lagos Island was the epicentre of the outbreak with 106 cases; followed by Kosofe 49; Eti-Osa 38; Lagos mainland 30 and Ojo 17.
Other LGAs affected are Ikorodu 16; Kosofe 16; Shomolu 11, Surulere has nine; Apapa -eight; Mushin-eight; Ifako Ijaiye -eight; Mushin -five; Alimosho -four; Ajeromi Ifelodun -four; Oshodi-Isolo -three; Ikeja three; Ibeju Lekki -two; Badagry -two; and Amuwo-Odofin -one.
"Through community-based case finding and contact tracing, we have observed that the number of cases has peaked and is now significantly declining," he said.
He stressed that the state was intensifying its public health prevention campaigns to prevent a resurgence.
According to him, suspected cases are receiving free treatment at the state's public health facilities, in line with public health response protocols.
Abayomi said that the state was receiving support from the Nigeria Centre for Disease Control (NCDC), and International partners, including the World Health Organisation (WHO) and UNICEF.
He added that local non-governmental organisations are actively involved in raising awareness and conducting community-based surveillance efforts.
On cholera causes and transmission, Abayomi disclosed that cholera is caused by contaminated water and food and transmission common in areas with inadequate water treatment, poor sanitation, and insufficient hygiene.

Speaking on treatment, Abayomi stressed that immediate action on rehydration was key, adding that oral rehydration salts (ORS) are crucial.
