Cameroon is facing an outbreak of measles, a disease endemic in the country. Between Epidemiological Week (EW) 1 to 13 of 2023, a total of 1,440 suspected cases and no deaths have been reported in the country.

Of the total reported cases, 223 have been confirmed with IgM+ results, 949 have been epidemiologically linked, and 21 cases were clinically compatible with the measles case definition.

Of the total cases reported in 2023, the Center region recorded the most cases with 597 (42.6%), followed by Littoral (381; 26.5%), Nord (146; 10.4%), Sud Ouest (92; 6.6%) ), Extreme Nord (82; 5.9%), Nord Ouest (59; 4.2%), Est (37; 2.6%), Ouest (22; 1.6%), Adamaoua (12; 0.9%) and Sud (12; 0.9%) ). The national measles incidence rate is 5.1 cases per 100,000 inhabitants, with the highest burden in the Center region, which has 11.3 cases per 100,000 inhabitants.

The epidemiological situation began to deteriorate around EW 42 of 2022, peaking at EW 6 of 2023.

Between EW 14/2022 and EW 13/2023, Cameroon reported 3,212 cases. During this period, active measles outbreaks were reported in 83 health districts in 10 regions. Of the total cases reported during this period, 12.6% occurred in children aged 0 to 8 months and 54.1% in children aged 9 months to 5 years.

In the same period, measles was not vaccinated in 98.1% of cases. Routine vaccination rates in 2022 are lower in affected health districts. By February 2023, 27.2% of health districts experiencing active outbreaks had less than 50% vaccination coverage for the routine first dose. Similarly, 79.2% of health districts experiencing active outbreaks had routine second-dose vaccination rates below 50%. Optimal measles vaccination coverage should be maintained at approximately 95% or higher to provide adequate immunity.
