NCDC REVIEWS LASSA FEVER OUTBREAK RESPONSE AMIDST REDUCING NUMBER OF CASES

The Nigeria Centre for Disease Control (NCDC) has reported a decrease in the number of Lassa fever cases reported weekly in the country. This is following the intensive response to the Lassa fever outbreak declared in Nigeria on the 21st of January 2019.

Since the beginning of the outbreak, NCDC has activated an Emergency Operations Centre (EOC) to coordinate response activities. The EOC includes representatives from the World Health Organization (WHO), Federal Ministry of Agriculture and Rural Development, Federal Ministry of Environment, Médecins Sans Frontières, UK Public Health Rapid Support Team, US Centers for Disease Control and other partners. In addition, state level EOCs were activated in Edo, Ondo, Ebonyi and Plateau.

In the last reporting week ending on the 17th February 2019, 25 new confirmed cases of Lassa fever were reported. So far, a total of 355 confirmed cases with 75 deaths have been recorded between January 1st and February 17th, 2019 from 20 states across 57 Local Government Areas. Over the past three weeks, there has been a downward trend in new cases.  The number of new cases being reported are lower, compared to the same period during the 2018 outbreak.

Despite the reduction in new cases, response activities are being intensified at the national and state level. Rapid Response Teams (RRTs), which include colleagues from Federal Ministry of Agriculture and Rural Development and Federal Ministry of Environment are supporting the response in high burden states (Edo, Ondo, Ebonyi, Plateau and Bauchi).

In addition, the NCDC has supported states in ensuring full availability of drugs, personal protective equipment, reagents and other supplies required for case management and diagnosis of Lassa fever. There has been no single stock-out reported in any state.

An outbreak review meeting was convened by the NCDC on the 15th of February 2019. The goal was to review response activities, discuss lessons learned and improve outcomes of the outbreak. The review highlighted significant improvement in the 2019 response as evidenced by the early decline in the number of cases when compared to the 2018 outbreak.

These improvements have been attributed to various factors including the early deployment of One-Health national RRTs, strengthening of Lassa fever treatment centres, enforcement of environmental sanitation, introduction of the Infection Prevention and Control (IPC) ring strategy, risk communications activities, high level advocacy, operational research into response activities, and others.

The surveillance data from previous outbreaks indicate that the typical peak transmission season for Lassa fever has not passed. Therefore, Nigerians must continue to practice preventive measures to avoid infection. Prevention of Lassa fever relies on promoting good community hygiene to discourage rodents from entering homes. Other effective measures include storing grains and other foodstuff in rodent-proof containers, proper disposal of garbage far from the home, and maintaining clean households. All food should be well prepared, and family members should always be careful to avoid contact with blood and body fluids while caring for sick persons.

Healthcare workers are urged to maintain a high index of suspicion for Lassa fever when handling patients, irrespective of their health status. Lassa fever should be considered in patients with fever, headache and malaise, in whom Malaria has been ruled out with a rapid diagnostic test (RDT), especially when patients are not getting better. Health workers should adhere to standard precautions including wearing protective apparels when handling suspected Lassa fever patients. The revised Lassa fever case management guidelines are available on the NCDC website, www.ncdc.gov.ng.

Lassa fever is a viral infection caused by the Lassa fever virus, primarily transmitted to humans through direct contact, eating food or drinking water contaminated with urine, faeces, saliva or blood of infected rats. Person-to-person transmission is through contact with blood, urine, saliva, throat secretion or semen of an infected person. The disease can be treated, with early presentation to a healthcare facility greatly increasing the chances of survival. Early signs of the disease include sudden fever, sore throat and general body weakness
