An epidemic of yellow fever and measles announced in the North West

LEBLEDPARLE.COM MARCH 2, 2022

Health officials from the North West Regional Public Health Delegation revealed that there was an outbreak of yellow fever and other outbreaks in the North West region.

Two cases of yellow fever have already been confirmed including one in Oku, Bui division, and another in Bamenda III subdivision. Meanwhile, there have also been confirmed measles cases in Ako Health District, Donga Mantung Division, and one person tested positive for Monkeypox disease in Benakuma Health District.

The North West Expanded Program on Immunization Coordinator, Dr Cornelius Chebo revealed that plans are underway for a mass vaccination campaign against these outbreaks.

He also called on the population to report any suspected case of disease to the nearest health district: “We want to emphasize that anyone who has unusual symptoms must go to the nearest vaccination center for more tests because we are already in an outbreak ,” Dr. Cornelius said.

Yellow fever: Cameroon wants to prevent the migration of patients to neighboring countries

RELEASED ON WEDNESDAY, 02 MARCH 2022 17:46

The National Public Health Observatory (ONSP) identifies a few epidemic outbreaks of yellow fever in the national triangle. Some, like that of the Logone-et-Chari department not far from Chad, in the Far North region, are located on the borders with neighboring countries. And because of permanent migration, health authorities fear an export of disease cases. A document made public this week by the ONSP indicates that the risk of exporting yellow fever cases is “significant”.

But it is the border between the North West region of Cameroon and Nigeria that worries the ONSP. The migratory flow at this border is exacerbated by the insecurity that reigns in this region due to the rise of irredentist discourse. In fact, this insecurity increases the frequency of population movements from Cameroon to the states of Taraba and Benue, in the south-east of Nigeria and, by extension, the probability of exporting cases.

Cameroon's fears are well founded. Because the World Health Organization (WHO) has always considered yellow fever as a migration disease. According to the explanations of experts in the matter, it is possible that an unvaccinated tourist visiting the country becomes infected and goes to develop the disease back home.

To avoid all forms of export, health authorities maintain vigilance at health posts at air, land and sea borders. Especially since Cameroon has still not reached collective immunity, which corresponds to 80% of the vaccinated population. This figure is currently stuck at 56%.

On February 22, the ONSP counted 4 new suspected cases. But the balance sheet is 42 cases for 7 deaths. 27 health districts are concerned. In addition to Logone-et-Chari, a few suspected cases have been identified in Douala, Bamenda, Foumbot… The eastern region on the border with the Central African Republic is also concerned.

Yellow fever: Cameroon prepares a response campaign to contain the rise in cases

PUBLISHED ON TUESDAY, 26 APRIL 2022 04:07

Cameroon is preparing to vaccinate 613,000 people against yellow fever in the Adamaoua and West regions. This response campaign, which targets people aged 9 months to 60 years, comes in a context of resurgence of the disease. Indeed, cases of yellow fever have been steadily increasing since 2017. "Thus, from 20 cases, the country went in 2021 to 44 cases recorded in 30 health districts spread over all ten regions of the country. In the first quarter of 2022, the number of cumulative cases over this entire period is 47 cases, including 7 deaths", indicates the Ministry of Public Health (Minsanté).

The epidemiological situation shows that the health districts of urban Ngaoundéré (Adamaoua), Malantouen and Foumbot (West) are the most affected. Hence the organization of this campaign in these two regions. Even if the figures seem less alarming, the Minsanté specifies that a single case of yellow fever is " a serious warning signal ", because the patient is contagious even if he does not present symptoms. The ministry does not give the start or end date of this campaign. We have just learned that the communication media (press kits, spots, banners, posters, flyers, etc.) have been developed as part of the deployment of this campaign. The objective is to prepare the populations to welcome the interventions of the campaign, but also to promote awareness of at least 95% of the target population on the disease.

Although Cameroon introduced yellow fever vaccination into the National Immunization Program (EPI) in 1988, vaccination coverage was estimated at around 57% in 2020, below the recommended minimum of 80%. This is the cause of the resurgence of the disease in the country.
