Lassa Fever

EVENT DESCRIPTION

Nigeria is currently facing an outbreak of Lassa fever,
with a significant increase in cases reported in early
2025. During epidemiological week 4 (20 - 26 January
2025), 76 new confirmed cases with 12 deaths were
reported from eight states: Ondo (25 cases, 2 deaths),
Taraba (17 cases, 6 deaths), Bauchi (14 cases, 1 death),
Edo (14 cases, 0 deaths), Ebonyi (3 cases, 1 death),
Gombe (1 case, 1 death), Nasarawa (1 case, 1 death),
and Kogi (1 case, 0 deaths).

From 30 December 2024 to 26 January 2025, a
cumulative total of 290 laboratory-confirmed cases with
53 deaths (CFR 18.3%) have been reported from 10
states across the country. Ondo (107 cases, 10 deaths),
Edo (61 cases, 10 deaths), Bauchi (49 cases, 5 deaths),
and Taraba (48 cases, 15 deaths) are the most affected
states, which together accounts for 91.4% of the total
confirmed cases and 75.5% of the deaths.

Cases range from 1 to 94 years of age, with a median
age of 32 years. Males are the most affected, accounting
for 52.6% (n=153) of the total cases reported Notably,
two healthcare workers have been infected.

Comparing the outbreak in 2025 to the same period in
2024, there has been a 12.4% increase in cases and a
10.4% increase in deaths, signalling a concerning trend.
The current rise in cases correspond to the usual period
of increase in Lassa fever cases in Nigeria, coming at the
beginning of the dry season in November with a sustain
increase until March.

PUBLIC HEALTH ACTIONS

The Nigeria Centre for Disease Control and Prevention
(NCDC) activated the Lassa Fever Incident Management
System (IMS), with coordination from the National Public
Health Emergency Operations Centre (PHEOC). National
Rapid Response Teams were deployed using a One
Health approach, and a risk assessment for the 2025
outbreak season was conducted.

Enhanced surveillance continues in affected states. So
far, 1 171 suspected cases have been reported across the
country. The viral haemorrhagic fever Case Investigation
Form (CIF) database and monitoring of emergency
indicators are being updated.

There are eight laboratories across the country with
capacity to test for Lassa fever. External Quality Assurance
panel preparations are underway.

Confirmed cases are managed at designated treatment
centers, with updated guidelines on case management
and safe burial practices disseminated. A monthly case
management webinar, launched by Georgetown Global
Health Nigeria (GGHN) in collaboration with NCDC, is
ongoing.

Infection Prevention and Control (IPC) compliance is
reinforced through offsite support for treatment centers,
with IPC guidelines and advisories distributed to health
workers and facilities.

Public awareness efforts include media campaigns,
press releases, and community sensitization in hotspot
LGAs. A community survey in Bauchi, Ebonyi, and Edo
states informed targeted communication strategies.
The Federal Ministry of Environment launched
environmental response campaigns in high-burden
states, including training workshops on rodent control
and Lassa fever prevention, in collaboration with
Breakthrough Action Nigeria (BA-N).

A Lassa fever commodity distribution plan was
developed, ensuring the ongoing supply of oral Ribavirin
to hotspot states. Other essential response items,
including personal protective equipment, body bags,
thermometers, sodium hypochlorite, hand sanitizers,
and information, education, and communication (IEC)
materials, have been distributed to states and treatment
centers.

SITUATION INTERPRETATION

The ongoing Lassa fever outbreak in Nigeria highlights
the persistent public health threat posed by the disease,
with a notable increase in cases and deaths compared
to the same period in 2024. This trend underscores the
seasonal nature of Lassa fever, which typically increases
during the dry season. The infection, caused by the
Lassa virus, is primarily transmitted to humans through
contact with food or household items contaminated by
rodent urine or feces, with secondary human-to-human
transmission occurring in healthcare and household
settings.

The rising case numbers, coupled with infections
among healthcare workers, emphasize the urgent need
for improved infection prevention and control measures.
The activation of the national response system,
enhanced surveillance, and expanded laboratory
capacity demonstrate a proactive approach based
on Nigeria’s experience in responding to the disease
over the years. However, continued efforts in risk
communication and community engagement remain
crucial to curbing transmission and reducing mortality.

The distribution of essential commodities, including Ribavirin, PPE, and rodent control measures, is a positive step, but
sustained intervention is necessary to prevent further escalation of the outbreak.
