Hemorrhagic fever: 404 cases and 42 deaths in Mauritania and Senegal according to the WHO
Sahara Media1 day ago
The World Health Organization announced that it had recorded 404 confirmed human cases of hemorrhagic fever, including 42 deaths in Mauritania and Senegal, between September 20 and October 30, 2025, while warnings were issued about the high risk of the infection spreading in the region.
The organization explained that current environmental and climatic conditions, including periods of heavy rainfall and the proliferation of mosquitoes, have contributed to creating an environment conducive to a wider spread of the disease, particularly in rural areas where agricultural and animal activity is intense.
The WHO has assessed the current risk level as high at the national level in Mauritania and Senegal, medium at the regional level, but low at the global level for the time being.
She called for the adoption of a "one health" approach, which integrates human, animal and environmental health to ensure an effective and comprehensive response reducing the risks of cross-border transmission.
The WHO stressed the need to intensify field surveillance and adherence to individual prevention measures, such as the use of insecticides and the wearing of protective equipment for livestock workers, while raising awareness among local communities about the dangers of direct contact with infected animals.
The organization also stressed that controlling the hemorrhagic fever epidemic requires close cooperation between the ministries of health, agriculture and environment of both countries, as well as support from international organizations to provide the prevention equipment and laboratories needed for early detection and isolation of cases.

Diphtheria and Rift Valley Fever: Mauritania on alert!
Essi Akofa 9 hours. In the news , Africa top success
Mauritania has recorded a total of 36 deaths from diphtheria and Rift Valley fever in recent weeks. The government has announced that both diseases have "entered a phase of decline."
According to the government spokesperson, 23 people died from diphtheria, while 13 deaths were recorded due to Rift Valley fever.
However, the Mauritanian government warns: this positive development "must not be a reason to relax preventive measures . "
Diphtheria is a contagious infectious disease that affects the central nervous system and other organs, resulting in death by asphyxiation. It is characterized by throat pain, fever, swollen neck glands, and weakness.
Rift Valley fever (RVF) is an acute viral disease that primarily affects livestock and is transmitted to humans through the bites of infected mosquitoes, contact with infected animals, or consumption of animal products. It manifests in humans as fever, headache, and muscle and joint pain.

Diphtheria and Rift Valley Fever in Assaba: The Situation Worsens, the Silence of the Authorities Is Worrying
The Assaba region is currently facing a worrying dual health crisis. Ninety-seven cases of diphtheria have been recorded there, including seven deaths in the commune of Tenaha and another in Kankossa, according to a health official interviewed by the Kiffa News Agency.
The same official specified that the majority of patients have recovered, and that to date, only 10 patients remain under medical surveillance.
Meanwhile, nine cases of Rift Valley fever have been treated in the region. Four patients have died, while four others remain hospitalized at the Kiffa Hospital Center. Two of the reported cases came from regions outside Assaba.
Despite the gravity of the situation, local health authorities have maintained a near-total silence, with no public communication on the progress of the two epidemics. This lack of transparency is disturbing public opinion and raising many questions.
For many local stakeholders, this lack of transparency risks compromising prevention efforts by preventing the population from adopting the necessary protective measures. Without clear information, citizens feel left to their own devices and tend to neglect basic health rules.

Rift Valley Fever Epidemic Situation Report 2025
On 10/11/2025
Mauritania is currently facing a wave of Rift Valley Fever, with the first outbreak recorded on September 15, 2025, in the village of Cham, in the Dar El Barka municipality, in the Bokki district of Brakna province.
As of October 11, 2025, veterinary services have recorded a total of 44 outbreaks distributed across 22 districts in ten states, as shown in the image.
It also denied the suspicion of 24 hotspots, after analyzing 715 samples, of which 192 were positive.
It is noteworthy that the positive cases in Tevragh Zeina, Lekser and Toujounine were not accompanied by any symptoms.
Rift Valley Fever is a seasonal, zoonotic viral disease that primarily infects animals through mosquito bites. It can be transmitted to humans through direct contact with the blood and organs of infected animals, as well as through contact with animal tissues during slaughter or assisted births, other unprotected contact with infected animals, and the consumption of milk and meat contaminated with the virus.
Synchronous miscarriages and death of young animals are among the most common symptoms of Rift Valley fever in animals, especially when accompanied by mosquito and vector activity and fever in humans.
It is worth noting that the veterinary services have begun early monitoring of this disease, starting last August, by equipping 32 detection herds of small ruminants in wetlands throughout the country, which made it possible to discover the two foci of Mektaa Lahjar and Tamchekett.
When the first outbreak appeared, the Ministry's central and regional departments raised their alert level and increased monitoring, tracking, rapid reporting, and the taking of samples and sending them quickly to the reference laboratory in Nouakchott to confirm or deny suspicions.
This is in addition to tightening control and inspection of meat in slaughterhouses and slaughtering areas.
The technical services also carried out awareness campaigns for citizens through the media about the danger of this disease, its transmission methods, and its prevention.
In light of this alarming situation, the Ministry recommends that citizens adhere to the following guidelines:
- Avoid direct contact with sick or dead animals.
- Heat milk and cook meat well.
- Use protective equipment when handling animals.
- Immediately report any deaths or any symptoms indicating this epidemic.
- Take preventive measures for animals against mosquito bites by using insecticides.

Report on the Situation of the Rift Valley Fever Epidemic 2025
Dated 5/10/2025
Mauritania is currently facing a wave of Rift Valley Fever, with the first outbreak recorded on September 15, 2025, in the village of Al-Sham, in the Dar El-Barka municipality in the Boki district of Brakna province.
As of October 4, 2025, veterinary services have recorded a total of 17 outbreaks distributed across 15 districts in eight provinces, as shown in the image.

Rift Valley Fever (RVF) is a seasonal, zoonotic viral disease that primarily infects animals through mosquito bites. It can be transmitted to humans through direct contact with the blood and organs of infected animals, as well as through contact with animal tissue during slaughter or assisted births, other unsafe contact with infected animals, and the consumption of milk and meat contaminated with the virus.
Simultaneous abortions and the death of young animals are among the most common symptoms of Rift Valley Fever in animals, especially when accompanied by mosquito and vector activity and fever in humans.
It is worth noting that veterinary services have begun early monitoring of this disease, starting last August, by equipping 32 scouting herds of small ruminants in wetlands across the country, which has enabled the detection of the two outbreaks in Mektaa Lahjar and Tamcheket. Upon the emergence of the first outbreak, the Ministry's central and regional departments heightened their vigilance, increasing monitoring, tracking, and rapid reporting, as well as taking samples and sending them promptly to the reference laboratory in Nouakchott to confirm or deny suspicions.

Trarza: Worrying spread of Rift Valley fever among camel herds
Health officials are concerned about the rapid spread of Rift Valley fever among camel herds in the Trarza province of southwest Mauritania.
According to local sources, the most affected areas are the Rkiz and Boutilimit departments, where numerous suspected cases have been reported in recent days. The disease, transmitted primarily by mosquitoes and contact with infected animals, poses a major risk to livestock farmers, already weakened by climatic and economic conditions.
Veterinary and health services are being mobilized to identify outbreaks, take samples and launch awareness campaigns among rural populations on preventive measures: avoid all direct contact with sick animals, boil milk, cook meat thoroughly, and report any abnormal mortality in livestock.
No measures restricting the movement of livestock have yet been announced, but authorities are calling for maximum vigilance throughout the region.

FVR PRESS RELEASE
Epidemiological situation of Rift Valley Fever (RVF) in the Islamic Republic of Mauritania
Nouakchott, September 29, 2025
The Ministry of Health informs the Mauritanian population that it has confirmed three cases of Rift Valley Fever (RVF), which unfortunately led to the death of the affected people in the wilayas of Trarza (Rosso), Brakna (Alég) and Assaba (Kiffa).
Situation under control
Faced with this situation, health authorities immediately activated the epidemic response plan. A national crisis committee has been established and is working in coordination with the World Health Organization (WHO) and our technical partners to contain the spread of this disease.
It is important to emphasize that no transmission from one person to another has been scientifically established for this disease.
Ongoing epidemiological investigations confirm that the identified cases are linked to contact with infected animals or their products.
What is Rift Valley Fever?
RVF is a viral disease that primarily affects livestock (sheep, goats, cattle, camels) and can occasionally affect humans. In the majority of cases (over 98%), infection in humans remains mild, manifesting itself with flu-like symptoms: fever, headache, muscle aches, and fatigue.
How is the disease transmitted?
Transmission to humans occurs mainly through:
• Direct contact with the blood or organs of infected animals during slaughter or handling
• Consumption of raw milk or undercooked meat from infected animals
• Bites from infected mosquitoes (rarer)
The disease is NOT transmitted from person to person.
Preventive measures for the population
The Ministry of Health calls on all citizens, particularly breeders, butchers and veterinarians, to strictly respect the following measures:
For livestock professionals:
• Wear gloves and protective equipment when handling sick animals
• Immediately report any unexplained abortions in the herd to the veterinary services
• Avoid direct contact with animal blood and bodily fluids
• Wash your hands regularly with soap and water
For the entire population:
• Cook meat thoroughly before consumption
• Boil the milk before drinking it
• Avoid consuming animal blood
• Use mosquito nets and repellents, especially at nightfall
• Consult a health center immediately in case of fever, headache or muscle pain
Increased surveillance
The epidemiological surveillance system has been strengthened across the country. All health facilities have been alerted and trained to manage suspected cases early. Rapid investigation teams have been deployed to affected areas.
Message of reassurance
The Ministry of Health reassures the population that:
• The situation is under control and is being rigorously monitored
• Health services are fully mobilized and have the necessary resources
• Preventive measures, if followed, are very effective
• Cooperation with international organizations guarantees optimal support
Call for collective responsibility
In light of this situation, we call on all citizens to demonstrate responsibility by implementing preventive measures and avoiding the spread of unfounded rumors. Official information will be provided exclusively by the Ministry of Health.
For updated information, follow the official channels of the Ministry of Health.
Together, let’s prevent and protect our health!
