Measles morbillivirus (MV) is one of the most contagious human pathogens.
MV infection occurs worldwide, sporadically or through outbreaks, such as the current outbreak in South Africa. Since late 2022, MV outbreaks have been declared in 5 provinces, namely, Limpopo, Mpumalanga, North West, Gauteng and Free State. Since the start of the outbreak, a total of approximately 400 cases have been confirmed. Due to the highly infectious nature of the virus, coupled with low immunization coverage, a risk of a broader, national outbreak is high. Clinicians should be on high alert for potential MV cases, which will assist with early detection and general outbreak response measures.
