Patterns of age-specific mortality in children in endemic areas of sub-Saharan Africa (Publications)
of the age- and season- dependence of malaria mortality is an important prerequisite for epidemiologic models of malaria immunity. However, most studies of malaria mortality have aggregated their results [...] stable endemic Plasmodium falciparum malaria. We use verbal autopsies (VAs) to estimate the proportion of deaths by age group due to malaria, and thus calculate malaria-specific mortality rates for each site [...] attributed to malaria. The overall age patterns of malaria mortality were...
Human unconventional T cells in <em>Plasmodium falciparum</em> infection (Publications)
field of malaria immunology. Significant advances in our basic understanding of unconventional T cell biology in rodent malaria models have been made, however, their roles in humans during malaria are less [...] tissues, and long-lasting expansions and functional alterations were observed upon malaria infection in malaria naïve and malaria pre-exposed volunteers. Here, we review the current understanding of involvement [...] Malaria is an old scourge of humankind and has a large negative impact...
A good night's sleep and the habit of net use: perceptions of risk and reasons for bed net use in Bukoba and Zanzibar (Publications)
BACKGROUND: Intensive malaria control interventions in the United Republic of Tanzania have contributed to reductions in malaria prevalence. Given that malaria control remains reliant upon continued use [...] perceived risk of malaria had decreased among the respondents, and malaria control interventions were credited for the decline. Participants cited reductions in both the severity of malaria and in their perceived [...] perceived susceptibility to malaria. However, malaria was still...

individuals can be stimulated by malaria parasites. Here, we show that nine from 11 blood samples, naturally infected with malaria parasites, could stimulate proliferation of a malaria-specific T cell clone derived [...] the T cell response of naive donors to malaria parasites, processing of parasite antigens is blocked by chloroquine and monensin, and activation of 36 of 41 malaria-specific clones tested was restricted [...] activation of cross-reactive memory T cells by malaria parasites...

Females had a lower prevalence of malaria (28.8%) compared [...] health impact of STH and malaria co-infection is inconclusive. The current study aimed to report the malaria and STH infection epidemiology in the continental region of Equatorial Guinea. METHODS: We performed [...] infected with T. trichiura had malaria parasites compared with those...

Most respondents [...] linked malaria to mosquitoes (76%) and already used mosquito nets (52%). But local understandings of severe malaria differed from the biomedical concept and were not linked to mosquitoes or malaria. A social [...] Since 1997 the WHO has been recommending an integrative strategy to...
Profile: the rusinga health and demographic surveillance system, western Kenya (Publications)

The project aims to eliminate malaria from Rusinga Island using the nationwide adopted strategy for malaria control (insecticide-treated [...] surveillance is to measure the effectiveness of the trial on clinical malaria incidence, and to monitor demographic, environmental and malaria-related data variables. At the end of 2014, the 44 km2 island had [...] surveyed for clinical malaria. Following each round of surveillance, a...
From <em>Plasmodium vivax</em> outbreak to elimination: lessons learnt from a retrospective analysis of data from Guantang (Publications)
BACKGROUND: Malaria was once a serious public health problem in China, with Plasmodium vivax the major species responsible for more than 90% of local transmission. Following significant integrated malaria control [...] control and elimination programmes, malaria burden declined, and since 2017 China has not recorded any indigenous case. To understand the historical malaria transmission patterns and epidemic characteristics [...] regarding Anopheles sinensis. RESULTS: Following 25 years of...

Malaria parasite densities also varied [...] to determine the impact of urbanization on the malaria infection (parasite) rate and parasite density, and their consequences on the heterogeneity of malaria transmission in urban Abidjan. Specifically we [...] tly between them. These results confirm the involvement of...
Spatial patterns of <em>Plasmodium vivax</em> transmission explored by multivariate auto-regressive state-space modelling - a case study in Baoshan... (Publications)
The transition from the control phase to elimination of malaria in China through the national malaria elimination programme has focussed attention on the need for improvement of the surveillance- response [...] (IDIRMS). The best MARSS model indicated that malaria transmission in the study area during 36 months could be grouped into three clusters. The estimation of malaria transmission patterns showed a downward trend [...] cluster cases have occurred. This study aims to explore the spatial...
