Treating children in sub-Saharan Africa’s malaria-endemic areas with a monthly preventive drug regimen during the rainy season reduced children’s deaths from the disease by up to 57%, a study found.

Coverage of antenatal iron and folic acid supplementation (IFAS) and intermittent preventive treatment of malaria in pregnancy (IPTp) remains low in many countries. Evidence on the most effective ways to increase both IFASIPTp is mixed overall, with only few studies directly identifying cost-effective ways to increase coverage of both interventions. The proposed study aims to assess the cost, impact and relative cost-effectiveness of two complementary strategies of increasing IFAS and malaria chemoprophylaxis coverage among pregnant women relative to the current default system in a rural low-income setting of sub-Saharan Africa.
Hydroxychloroquine is an antimalarial drug being tested as a potential treatment for the novel coronavirus disease 2019 (COVID-19) pandemic caused by the severe acute respiratory syndrome coronavirus 2. Although the efficacy of hydroxychloroquine for COVID-19 remains uncertain, it may serve as a potential prophylactic agent especially in those at high risk, such as healthcare workers, household contacts of infected patients, and the immunocompromised.
A prophylactic antimalarial drug that is both effective for protection and improves compliance is in high demand.
Malaria drugs chloroquine and hydroxychloroquine are currently being evaluated in a number of clinical trials as active treatments against SARS-CoV-2 virus. They are also postulated for pre and postexposure prophylaxis for the prevention of COVID-19. It has been recently shown that both molecules inhibit in-vitro the entry of the virus in the cell, and they can stop the cytokine storm derived from the infection alongside impeding T cell activation [1,2]. In particular, hydroxychloroquine is a drug with an excellent safety profile, even for pregnant women. Furthermore, hydroxychloroquine has been successfully used during decades for the management of rheumatologic diseases modulating inflammation and organ damage .
Ivermectin is safe and widely used for treating helminth infections. It also kills arthropods feeding on treated subjects, including malaria vectors. Thus, ivermectin mass drug administration as an additional tool for malaria control is being evaluated by WHO. As in vitro data, animal experiments and epidemiological observations suggest that ivermectin has a direct effect on the liver stages of the malaria parasite, this study was designed to assess the prophylactic effect of ivermectin on Plasmodium falciparum controlled human malaria infection.
The British Army adopted mefloquine (Lariam) as its preferred drug for chemoprophylaxis against malaria in 1993. Treatment doses of mefloquine had already been reported to cause an acute brain syndrome. In 1996, army doctors reported a private soldier who, after six doses of mefloquine prophylaxis, saw the Grim Reaper standing behind the chaplain, heard incoherent voices, and was admitted to a psychiatric hospital; more reports followed.
The effectiveness of malaria chemoprophylaxis is limited by a lack of compliance in travellers. This study assesses the demographic, travel-related, and psychosocial determinants of non-compliance with chemoprophylaxis.
