Could China's journey of malaria elimination extend to Africa?

World Health Organization (WHO) certified China malaria-free on June 30, 2021, which brightens the goal of global malaria elimination efforts. China contributed its unique innovations to the global community: Artemisinin, discovered by Tu Youyou, has saved millions of lives globally; the "1-3-7" norm developed in 2012, has been adapted in the local contexts of countries in the Southeast Asia and Africa. How to the targets of Global Technical Strategy for Malaria (GTS) 2016-2030.

Longitudinal Comparison of Antibiotic Resistance in Diarrheagenic and Non-pathogenic Escherichia coli from Young Tanzanian Children.

Enteroaggregative, enteropathogenic, and enterotoxigenic Escherichia coli contribute significantly to the burden of diarrheal infections particularly in developing countries. Antibiotic resistance is increasingly common among bacterial pathogens including pathogenic E. coli.

Community mass treatment with azithromycin for trachoma: Factors associated with change in participation of children from the first to the second round.

Background: Mass drug administration (MDA) with azithromycin is an important part of trachoma control programs. Maintaining high participation among children is challenging.

Aim: We assessed factors identifying households with a child who changed participation from the first MDA to the second MDA compared to households where all children participated at both MDAs.

Short-term malaria reduction by single-dose azithromycin during mass drug administration for trachoma, Tanzania.

Single-dose mass drug administration of azithromycin (AZT) is underway to eliminate trachoma worldwide. Studies in Ethiopia showed a reduction in all-cause childhood deaths after administration. To examine the effect of single-dose AZ MDA on prevalent malaria infections in a large prospective cohort of children and parents in Dodoma Province, Tanzania, we quantified the temporal prevalence of malaria parasitemia by real-time PCR for 6 months after single-dose AZT.

Increased carriage of macrolide-resistant fecal E. coli following mass distribution of azithromycin for trachoma control.

Background: Mass drug treatment with azithromycin (MDA) is part of the WHO-endorsed 'SAFE' strategy for trachoma control in endemic communities. MDA has been associated with reduced trachoma prevalence and short-term reductions in other bacterial infections, but can also lead to increased circulation of macrolide-resistant bacteria.

Methods: We prospectively monitored macrolide resistance in fecal E.

Mass distribution of azithromycin for trachoma control is associated with increased risk of azithromycin-resistant Streptococcus pneumoniae carriage in young children 6 months after treatment.

Background: Emerging evidence suggests that the mass distribution of azithromycin for trachoma control (MDA) may increase circulation of macrolide resistance in bacteria associated with severe pediatric infections in treated communities.

Methods: We examined the effect of MDA on nasopharyngeal carriage of antibiotic-resistant Streptococcus pneumoniae among 1015 young children living in rural Tanzania. MDA with a single dose of oral azithromycin was provided in 4 of 8 communities where trachoma prevalence was ≥10%.

Trends in weekly reported net use by children during and after rainy season in central Tanzania.

Background: The use of long-lasting insecticidal nets (LLINs) is one of the principal interventions to prevent malaria in young children, reducing episodes of malaria by 50% and child deaths by one fifth. Prioritizing young children for net use is important to achieve mortality reductions, particularly during transmission seasons.

Methods: Households were followed up weekly from January through June 2009 to track net use among children under seven under as well as caretakers.

Azithromycin mass treatment for trachoma control: risk factors for non-participation of children in two treatment rounds.

Background: Persistent non-participation of children in mass drug administration (MDAs) for trachoma may reduce program impact. Risk factors that identify families where participation is a problem or program characteristics that foster non-participation are poorly understood. We examined risk factors for households with at least one child who did not participate in two MDAs compared to households where all children participated in both MDAs.

Mass distribution of azithromycin for trachoma control is associated with short-term reduction in risk of acute lower respiratory infection in young children.

Background: We evaluated the effect of a single mass distribution of azithromycin for trachoma on the risk of acute lower respiratory infection (ALRI) during a 6-month period among young children living in 8 communities in rural Tanzania.

Methods: In 8 communities, a cohort of randomly selected children (n = 1036) was followed for incidence of ALRI episodes. Mass treatment for trachoma using a single dose of oral azithromycin was provided in 4 of the 8 communities where trachoma prevalence was .

Association of mass treatment with azithromycin in trachoma-endemic communities with short-term reduced risk of diarrhea in young children.

A cohort study was designed to assess the impact of mass distribution of azithromycin (MDA) for trachoma control on incidence over six months of pediatric diarrhea in eight communities in rural Tanzania. A single dose of azithromycin was offered to all residents in four communities, where trachoma prevalence was ≥ 10%. Four geographically matched communities had trachoma prevalences < 10% and did not receive MDA.

Prevalence and density-related concordance of three diagnostic tests for malaria in a region of Tanzania with hypoendemic malaria.

Accurate malaria diagnosis has dual roles in identification of symptomatic persons for effective malaria treatment and also enumeration of asymptomatic persons who contribute to the epidemiologic determinants of transmission. Three currently used diagnostic tests, microscopy, rapid diagnostic tests (RDTs), and real-time PCR, all have different sensitivities and specificities, which are parasite density dependent. Here, we compare their concordance among 451 febrile episodes in a cohort of 2,058 children and adults followed over 6 months in a region in central Tanzania with hypoendemic malaria.
