Sierra Leone has recorded a measles outbreak with confirmed cases reported across several districts nationwide, prompting renewed calls for urgent vaccination, public awareness, and community surveillance to prevent further spread of the disease.

According to a public health advisory issued by [FOCUS1000](https://focus1000.org?utm_source=chatgpt.com), the National Public Health Agency (NPHA), working in collaboration with the Ministry of Health, confirmed that 41 measles cases were recorded between January and April 2026 in eight districts across the country.

The affected districts include Western Area Urban, Western Area Rural, Bo, Kenema, Kono, Port Loko, Bombali, and Tonkolili. Health surveillance data cited in the advisory showed a national test positivity rate of 75 percent, while Western Area Urban was identified as the most affected district.

The advisory further stated that 15 confirmed cases have so far been recorded in the Western Area Urban district, including nine new cases reported in April alone, indicating what health authorities described as ongoing community transmission within Freetown.

FOCUS1000, a Sierra Leonean non-governmental organization that supports maternal and child health initiatives, said the outbreak poses a serious public health threat, particularly to unvaccinated children who are at greater risk of severe complications. The organization warned that measles can lead to pneumonia, diarrhea, blindness, encephalitis, and death if not properly controlled.

The organization also stressed that the highly contagious nature of measles increases the risk of rapid spread in communities with low vaccination coverage, threatening both children and adults who lack immunity.

In its public statement, FOCUS1000 reaffirmed its commitment to supporting national health authorities in strengthening surveillance, expanding vaccination campaigns, and promoting accurate public health information to contain the outbreak.

“Measles is highly contagious — but it is preventable through vaccination,” the organization stated, while urging parents and caregivers to ensure that children receive routine measles vaccinations and that suspected cases are promptly reported to nearby health facilities for immediate medical attention.

The organization additionally called on community members and stakeholders to help combat misinformation by sharing verified health information within their communities.

The Government of Sierra Leone, through the Ministry of Health and the National Public Health Agency, continues to intensify response efforts aimed at containing the outbreak and protecting vulnerable populations, particularly children.

Public health experts say early vaccination, rapid detection of suspected cases, and community cooperation remain critical to stopping the spread of measles and preventing additional infections across the country.
