{ Our Vision & Methodology }

TAMTAM distributes free bed nets to prevent malaria in a cost-effective, high impact and evidence-based manner.

TAMTAM conducts operational research on bed net distribution to help improve the use of bed nets worldwide.


We are a volunteer organization with zero personnel costs. For less than seven dollars, we provide a bed net to a vulnerable individual or household. Bed nets can reduce child mortality by approximately twenty percent.

High Impact

Based on recommendations by WHO and best practices in the field, we have a two-pronged approach:

  • Targeted continuous distribution through health clinics, which reaches vulnerable populations such as pregnant women and children under five. Additionally, this helps achieve broader health objectives by using bed nets to encourage preventive care such as prenatal examinations.
  • Mass distributions for the entire population, which deliver bed nets periodically to cover as many sleeping spaces as possible to achieve universal coverage in a given region. This helps reduce the number of infected mosquitos in the entire region to bring malaria to a permanently low level.


A wealth of scientific research confirms that insecticide-treated bed nets are highly effective at preventing malaria. TAMTAM distributes bed nets that comply with the WHO’s standards for insecticide-treated bed nets.

A study of TAMTAM's targeted continuous distribution approach in Kenya showed that a high percentage of bed net recipients were actively using the nets; in addition, TAMTAM significantly increased prenatal care attendance and HIV testing among pregnant mothers. As a result, TAMTAM's program proved to be extremely cost-effective, saving the lives of 18 babies per 1000 pregnancies.

A number of research studies show that mass distribution, in combination with routine distributions of bed nets, can bring malaria cases to a permanently low level. This is the case since the number of infected mosquitos declines when a large fraction of the population is covered. Many malaria-transmitting mosquitos are killed by the insecticide of the ITNs and those who don’t get exhausted when they have trouble finding a host. For that reason, all major malaria organizations, as well as the WHO, promote the two-pronged approach described above.

TAMTAM collaborates with policymakers and researchers to refine and implement best practices for malaria prevention.

  • We engage researchers, government officials and policymakers to identify outstanding operational and policy questions.
  • We match in-country development practitioners with researchers to conduct operational evaluations and generate evidence to guide malaria policy decision-making.

A randomized evaluation of TAMTAM’s Kenya program by Professor Jessica Cohen and Professor Pascaline Dupas found TAMTAM’s approach of free distribution to be clearly superior to cost sharing (in terms of lives saved without a significant drop in bed net utilization).

Two randomized control trials TAMTAM conducted in Uganda showed that using Community Health Workers to hang nets in recipient homes boosted short-term net usage by 30%, confirming that “hang-up” campaigns can be a highly cost-effective approach to boost net usage.
