Dear All,
Nigeria has been experiencing Lassa fever outbreak in the past six weeks in Bauchi, Nasarawa, Niger, Taraba, Kano, Rivers, Edo and Oyo states with the Federal Government stating that the number of reported cases since the outbreak is 76 with 35 deaths already recorded and 14 cases confirmed by laboratories. Although there has not been any reported case in Lagos, we need to take the necessary precaution in all what we do including educating ourselves on the causes of Lassa fever and improving on our hygiene both at work and at home.
According to the WHO, Lassa fever is an acute viral hemorrhagic illness caused by Lassa virus, a member of the arenavirus family of viruses and was first described in 1969 in the town of Lassa, in Borno State, Nigeria. It is transmitted to humans from contacts with food or household items contaminated with rodent excreta. The disease is endemic in the rodent population in parts of West Africa. The possibility of person-to-person infections with about 80% of the cases being asymptomatic and laboratory transmission makes it a very dangerous disease, particularly in the hospital environment in the absence of adequate infection control measures.
