Malaria and HIV, two of the world’s most deadly diseases, are widespread, but their distribution overlaps greatly in sub-Saharan Africa. Consequently, malaria and HIV coinfection (MHC) is common in the region. In this paper, pertinent publications on the prevalence, impact, and treatment strategie
...
s of MHC obtained by searching major electronic databases (PubMed, PubMed Central, Google Scholar, ScienceDirect, and Scopus) were reviewed, and it was found that the prevalence of MHC in SSA was 0.7%–47.5% overall. Prevalence was 0.7%–47.5% in nonpregnant adults, 1.2%–27.8% in children, and 0.94%–37% in pregnant women. MHC was associated with an increased frequency of clinical parasitemia and severe malaria, increased parasite and viral load, and impaired immunity to malaria in nonpregnant adults, children, and pregnant women, increased in placental malaria and related outcomes in pregnant women, and impaired antimalarial drug efficacy in nonpregnant adults and pregnant women. Although a few cases of adverse events have been reported in coinfected patients receiving antimalarial and antiretroviral drugs concurrently, available data are very limited and have not prompted major revision in treatment guidelines for both diseases. Artemisinin-based combination therapy and cotrimoxazole are currently the recommended drugs for treatment and prevention of malaria in HIV-infected children and adults. However, concurrent administration of cotrimoxazole and sulfadoxine–pyrimethamine in HIV-infected pregnant women is not recommended, because of high risk of sulfonamide toxicity. Further research is needed to enhance our understanding of the impact of malaria on HIV, drug–drug interactions in patients receiving antimalarials and antiretroviral drugs concomitantly, and the development of newer, safer, and more cost-effective drugs and vaccines to prevent malaria in HIV-infected pregnant women.

(2) destination-based measures, including mandatory vaccines (e.g. yellow fever, meningitis and polio), recommended vaccines depending on regional risks (e.g. cholera, typhoid, hepatitis A and rabies) and WHO-advised malaria prevention through mosquito protection and chemoprophylaxis. The third area covers vaccines for healthcare workers with direct patient or laboratory exposure, including hepatitis B, influenza, diphtheria, pertussis and others. The recommendations emphasise the importance of pre-travel medical consultations, adherence to host country requirements, and individualised risk assessments.

Its primary target audience is travel health practitioners and travel health professionals, who provide health advice to travellers on appropriate precautions to be taken to minimize any travel-related health risks in unfamiliar environments, before, during and after travel. The guidance may also be of interest to health authorities who intend to support travel health professionals in their jurisdiction or develop
health advice for their population. It may also be of interest to travellers who wish to obtain such information for themselves as well as those working in the travel industry, such as agents and organizers, airlines and shipping companies.

Malaria prevention measures include chemoprophylaxis (e.g. atovaquone-proguanil, doxycycline or mefloquine) and vector control methods such as insecticide-treated nets, insect repellents and environmental protection measures. Additional travel health risks covered include bites from other arthropods, envenomations, dog and mammal bites, food and water hygiene, traveller's diarrhoea, and considerations for pregnant women, infants, the elderly, and people with chronic conditions. It strongly recommends carrying a travel medical kit and having a pre-travel consultation. Overall, the document aims to minimise illness and ensure safe travel.

nt of resistance. Artemisinin-based combination therapies (ACTs), such as artemether–lumefantrine, artesunate–amodiaquine and artesunate–sulfadoxine/pyrimethamine, are highly effective in rapidly clearing parasites and reducing gametocyte carriage. They are also generally well tolerated. Non-artemisinin combinations, quinine-based regimens and novel combinations (e.g. piperaquine–dihydroartemisinin) offer alternative therapeutic options, although clinical experience with these remains limited. Although ACTs are the preferred first-line treatment, factors such as cost, local drug resistance patterns, safety during pregnancy and paediatric use must inform implementation and policy decisions.

The approved therapies — pyronaridine–artesunate, dihydroartemisinin–piperaquine and rectal artesunate — offer child-friendly formulations and are the first-line treatment for uncomplicated malaria caused by Plasmodium falciparum and P. vivax. Inclusion in the EMLc facilitates national adoption, improves access to high-quality treatments and addresses the disproportionate malaria burden among children under five. This supports global efforts to reduce malaria mortality and advance elimination.

A few countries, particularly Nigeria and the Democratic Republic of the Congo, carry the highest burden. Since 2000, Africa has significantly reduced malaria incidence and mortality, averting over 1.7 billion cases and 12 million deaths. Nevertheless, malaria continues to pose a significant health challenge, necessitating ongoing action and investment.
