EVENT DESCRIPTION

The Ministry of Health of Niger has reported the first ever case
of dengue in Abalak department, Tahoua region. The patient is a
47-year-old male Nigerien who arrived from Cuba on 13 August
2022.

On 14 August 2022, he exhibited flu-like symptoms, including
fever, arthromyalgia, body aches, cold and consulted a community
clinic in Niamey. The patient currently has no signs of bleeding;
however a complete blood analysis showed thrombocytopenia.
The case-patient has history of COVID-19 and dengue infection
in June 2022 in Cuba.

Basing on the history and clinical presentation, a sample collected
from the case and sent to the Centre de Recherche Médicale et
Sanitaire on 8 August 2022 tested positive for dengue fever. A
second sample sent to the Institut Pasteur in Dakar confirmed the
case-patient positive on 24 August 2022.

PUBLIC HEALTH ACTIONS

Health authorities in Niger have implemented the following
response activities:

Outbreak investigations are conducted by a joint team –
Directorate of Surveillance and Epidemic Response and
WHO;

Entomological assessments have been performed, including:
capturing of aedes mosquitoes (at the patient’s home and at
the clinic where the case was treated) for laboratory analysis
to look for evidence of contamination of these mosquitoes

The patient, his family and nearby communities have been
educated on best practices;

Sensitization of the health care facility personnel for better
surveillance of contacts of the confirmed case;

Identification and follow-up of contacts among health
workers and family members is underway

Strengthening surveillance, educating all health district
workers on the dengue case definition, especially those in
Abalak city.

SITUATION INTERPRETATION

Dengue is a mosquito-borne viral disease that has rapidly spread
in all regions of WHO in recent years. Dengue is unusual in Niger
and requires particular attention as the reported case of dengue
is the first-ever detected in Niger. Enhanced surveillance in the
case’s vicinity and among all contacts is essential. Detailed
investigations to identify the source of infection of the case
remain paramount.
