Objective: To understand the epidemiological characteristics and epidemic situation of malaria in Yancheng City, so as to provide the evidence for proposing the control strategy of malaria.
Methods: A retrospective investigation was employed. The epidemiological data of the definitely diagnosed malaria cases in Yancheng City from 2003 to 2011 were collected and analyzed for the epidemiological characteristics and epidemic situation of malaria.
Results: A total of 134 malaria cases were detected in 9 counties (cities, districts) of Yancheng City from 1993 to 2011, including 18 cases of local vivax malaria, 59 cases of imported vivax malaria, 56 cases of imported falciparum malaria and 1 cases of imported malariae malaria, which comprised 13.43%, 44.03%, 41.79% and 0.75% of the total cases, respectively. From 1993 to 2011, the total incidence of malaria was 0.3 per million to 2.9 per million, and the incidence of local malaria ranged between 0 and 0.6 per million, appearing low epidemic situation. Since 2006, no local malaria cases were detected for 6 successive years. A total of 56 cases of oversea imported falciparum malaria and 1 cases of imported malariae malaria were found from 2007 to 2011, and the number of imported falciparum malaria cases exhibited an increasing tendency year by year. The median interval from onset to treatment for these patients was 1 day, 58.96% of the patients went to clinic when they felt silk and the village clinic was their major choice for the first visit. All of the median intervals from onset to blood test, to diagnosis and to treatment were 4 days.
Conclusions: The transmission of local malaria tends to be gradually eliminated in Yancheng City, and the oversea imported falciparum malaria cases obviously increase. Currently, the surveillance and control of imported malaria should be given a high priority.

Background: To develop an effective vaccine against Plasmodium vivax, the most widely dispersed human malaria parasite, it is critical to understand how coinfections with other pathogens could impact malaria-specific immune response. A recent conceptual study proposed that Epstein-Barr virus (EBV), a highly prevalent human herpesvirus that establishes lifelong persistent infection, may influence P. vivax antibody responses.

Background: Thailand has made significant progress in malaria control efforts in the past decade, with a decline in the number of reported cases. However, due to cross-border movements over the past 5 years, reported malaria cases in Thailand have risen. The Malaria Infection Study in Thailand (MIST) involves deliberate infection of healthy volunteers with Plasmodium vivax malaria parasites, and the assessment of the efficacy of potential vaccine and drug candidates in order to understand acquired protection against malaria parasites.

Background: Dengue fever (DF) poses a growing global threat, necessitating a comprehensive one-health approach to address its complex interplay between human, animal, and environmental factors. In Oyo State, Nigeria, the true burden of DF remains unknown due to underdiagnosis and misdiagnosis as malaria, exacerbated by poor health-seeking behavior, weak surveillance systems, and inadequate health infrastructure. Adopting a one-health approach is crucial to understanding the dynamics of DF transmission.

Background: Malaria cases in the Republic of Korea decreased during the coronavirus disease 2019 pandemic but surged in 2023. Current models inadequately address spatial heterogeneity in transmission dynamics. This study aimed to address this by designing a region-structured model considering spatial heterogeneity based on regional malaria data from high-risk areas.

Purpose: Malaria remains a major global health challenge, particularly in sub-Saharan Africa and low- and middle-income countries (LMICs), contributing substantially to mortality and morbidity rates. In resource-limited settings, access to specialized diagnostic tests is often restricted, making basic blood analysis a valuable diagnostic tool. This study investigated the correlation between malaria infection and full blood count values in a rural region of Ghana during the 2022 rainy season, aiming to highlight diagnostic insights available from routine blood analyses.
