  • Summary

  • In recent weeks, malaria has resurfaced as a significant public health concern, particularly in northwest Congo, where a surge in malaria cases has prompted extensive investigations and response efforts.

    In the Equateur province of Congo, health officials are grappling with an outbreak that has resulted in over 1,000 reported cases and at least 60 deaths since late January. The World Health Organization (WHO) has been at the forefront of these efforts, conducting detailed epidemiological and clinical investigations to determine the cause of the illnesses. While malaria, a mosquito-borne disease prevalent in the region, is the primary suspect, other causes such as flu and typhoid are also being considered[1].

    The outbreak was first detected in the village of Boloko after three children who ate a bat died within 48 hours. The village of Bomate, approximately 200 kilometers from Boloko, has been the hardest hit, with 98% of the cases and 86% of the deaths recorded there. Tests have shown that 54.1% of patients in the Basankusu health zone tested positive for malaria, aligning with the symptoms reported, which include fever, body aches, chills, and other severe health issues[1].

    Despite the challenges posed by remote locations and limited access to medical supplies, the WHO and local health authorities are working to provide medical care and investigate the root causes of the outbreak. The lack of medication in local hospitals has forced some families to seek private supplies, highlighting the need for urgent and sustained support[1].

    In the broader context of malaria control, significant advancements have been made in the development and deployment of malaria vaccines. The WHO has recommended two malaria vaccines, RTS,S/AS01 and R21/Matrix-M, for use in children living in areas with moderate to high malaria transmission. These vaccines have shown substantial efficacy in reducing malaria cases, severe malaria, and all-cause mortality in children. The RTS,S vaccine, for instance, reduces clinical malaria by 39%, severe malaria by 30%, and all-cause mortality by 13%[2][4].

    The rollout of these vaccines is well underway, with 17 countries in Africa having introduced them into their childhood immunization programs as of December 2024. Additional countries are expected to follow suit in 2025, with the aim of saving tens of thousands of young lives annually. The availability of these vaccines is expected to meet the high demand, especially with the support of global health organizations like GAVI, which has established a co-financing policy to increase affordability[4].

    These efforts underscore the ongoing commitment to combating malaria, a disease that remains a major public health threat, particularly in sub-Saharan Africa. As research continues to develop more effective vaccines and treatments, the immediate response to outbreaks like the one in northwest Congo remains crucial in saving lives and controlling the spread of the disease.
