The National Centre for Disease Control (NCDC), the Nigerian agency responsible for the management of disease outbreaks, said in its week six update on Thursday that eight new deaths from Lassa fever were reported in three states.
“Four new healthcare workers were affected in Ondo, Delta and Kaduna states,” the NCDC said in the update.
It said the number of suspected cases has “increased significantly” compared with the situation in mid-January, from more than 700 to 1,708.
Confirmed cases have also shot up to 472, it said.
Lassa fever is a disease spread to humans through food or household items contaminated with rodent urine or faeces.
In 80 percent of cases, the fever is asymptomatic, but for some, the symptoms include high fever, headache, mouth ulcers, muscle aches, haemorrhaging under the skin and heart and kidney failure.
It has an incubation period of between six and 21 days and can be transmitted through contact with an infected person via bodily fluids and excretion.
