Six persons have died of cholera in Isolo Local Council of Lagos State after allegedly eating Abacha, a local delicacy.
Commonly called African salad, abacha is a delicious Nigerian meal that is native to Igbos. It is prepared from dried, shredded and fermented cassava, leaves of garden egg, stockfish, castor bean, palm oil and local spices.
The Commissioner for Health, Dr. Jide Idris, confirmed the deaths yesterday at a press conference. Idris told journalists: "The ministry was notified of an upsurge of diarhhoea diseases in some communities in Isolo Local Council Development Authority (LCDA).
"Following this, 45 cases were line-listed by the Epidemiology Unit of the Ministry. Six deaths were recorded among the 45 cases. Majority of the cases did not present with the classical rice-water stool, rather they presented with atypical diarrhoea and vomiting.
"Ano-rectal swabs were collected from 15 cases and taken to the Central Public Health Laboratory, Yaba, Lagos. Initially, there were no growths, however, continuous culture yielded Vibro cholerae from seven out of the 15 samples. The Vibrio cholera was later confirmed to be Ogawa strain.
"The main suspected source of infection is the salad called Abacha, a staple food of Isolo residents and adjoining local councils. Some domestic wells within the communities are also suspected. Samples of the Abacha salad and well water were collected and sent to the Lagos State Drug Quality Control Laboratory for analysis.
"The report of the analysis revealed the presence of Vibrio cholerae, Salmonella species and Escherichia coli in abacha and one of the two well water samples," he said.
According to the World Health Organisation (WHO), cholera is an acute diarrhoea disease with or without vomiting caused by bacteria referred to as Vibro cholerae and it is transmitted through ingestion of food or water contaminated with infective faeces.
Food or water contamination is usually due to poor sanitation and the source of contamination is usually other cholera cases when their infective watery stool gets into food or drinking water supplies.
Prevention of cholera can be achieved through basic water sanitation, such as boiling water of unclean sources. Cholera can kill within hours if left untreated.
The commissioner, however, said the state has instituted measures towards quick containment and control of the outbreak.
Idris explained: "Our health workers are in the community striving assiduously towards quick containment and control of spread of the disease. Chlorination of water supply has been intensified, awareness campaign is on-going and cases are been promptly diagnosed and appropriately managed in our hospitals."
