The Nigeria Centre for Disease Control(NCDC) in a statement released on March 4, says at least 78 people have been confirmed dead and 353 are infected in an “unprecedented” outbreak of Lassa fever in Nigeria. Here are three(3) important things you must be aware of, to stay healthy.

What is Lassa Fever?

Lassa fever is an acute viral hemorrhagic illness, endemic in most of West Africa, especially Nigeria, where it was discovered in 1969. Symptoms can be mild or severe, including hemorrhaging in the gums, eyes or nose.

According to the US Centers for Disease Control and Prevention, the disease is transmitted to humans through contact with food or items contaminated by multimammate rats — or through contact with bodily fluids from an infected person.

Mortality Rate

On average, Lassa fever is deadly in 1% of all individuals infected, with higher rates of 15% morbidity among people hospitalized with the illness. According to an NCDC report from March 4, the case fatality ratio in the latest outbreak was 23.8%.
Sixteen health workers were infected of whom four died within eight weeks of this outbreak.

When You Have Symptoms Of Fever Go To a Health Care Facility

The NCDC has said the country was facing an “unprecedented outbreak” as the disease has spread to 18 states since it began in January.  According to Dr. Chikwe Ihekweazu, director of the NCDC, many of the cases were self-managed and not tested at the onset because the illness was thought to be malaria, a disease endemic to Nigeria and whose symptoms mimic Lassa fever. Therefore, those with symptoms of fever should “go to a health care facility in order to get a test that will determine the cause of the fever.”
