Travel, malaria

Bouchra Trari, Mohamed Dakki
The Anopheles maculipennis complex has been implicated in the transmission of malaria, which was endemic in Morocco until 2010. Climate change, intensification of international travel and the permanent presence of the vector increase the risk of malaria re-emergence. Using polymerase chain reaction assay (PCR), this study attempts to identify the possible presence of the Maculipennis complex in several areas of Morocco, based on the concept of risk. Eighty-six mosquito specimens were analyzed using PCR amplification of the ITS2 (Internal Transcribed Spacer 2) sequence of ribosomal DNA...

BACKGROUND: Leptospirosis is an important zoonosis worldwide, nevertheless is often poor recognized in non tropical settings. In Thailand is becoming an emerging disease and Chiang Mai could become a popular spot to acquire the disease amongst travelers. METHODS: We describe three cases of imported leptospirosis undifferentiated fever after travelling to Thailand during the summer of 2015 diagnosed at two Spanish hospitals. RESULTS: Our three patients probably acquired leptospirosis while swimming in freshwater around Chiang Mai, a Thailand's northern region with moderate incidence of leptopirosis...

Few studies have analyzed the characteristics of patients who develop physical disorders after overseas travel. We retrospectively reviewed the medical records of 183 patients who visited Nara Medical University Hospital from 2008 to 2016 because of physical problems after traveling abroad. The main travel destinations were Southeast Asia (n = 100), Africa (n = 27), and South Asia (n = 23). The main reasons for the travel were leisure (n = 96), business (n = 51), and volunteer work (n = 19). The most common final diagnosis was gastrointestinal disease (n = 72), followed by febrile disease (n = 59) and respiratory disease (n = 19)...

Emerging evidence indicates that migrants from Plasmodium falciparum endemic regions are at risk of delayed presentation of P. falciparum malaria. We report three cases of P. falciparum malaria occurring years after arrival in Europe. All patients were originally from Sub-Saharan Africa. Two subjects had controlled HIV infection and one was a pregnant woman. We performed a literature review of all published cases of delayed presentation of P. falciparum in migrants and identified 32 additional cases. All cases but one originate from sub-Saharan Africa...

Malaria infection remains an important health threat to U.S. service members who are located in endemic areas because of long-term duty assignments, participation in shorter-term contingency operations, or personal travel. In 2017, a total of 32 service members were diagnosed with or reported to have malaria, which is the lowest number of cases in any given year during the 10-year surveillance period. The relatively low numbers of cases during 2012-2017 mainly reflect decreases in cases acquired in Afghanistan, a reduction due largely to the progressive withdrawal of U...

Persistent fever or FUO (fever of unknown origin) is defined by a fever of more than 1‑2 weeks that remains unexplained, after considerable diagnostic efforts. In the travelling child, in addition to cosmopolitan infectious diseases, tropical pathogens must absolutely be considered according to the regions visited and the activities practiced. A detailed history and a complete clinical examination are essential to decide which supplementary investigations will complete the basic assessment, which must contain the search for malaria in any child who has visited an endemic area...

BACKGROUND: Malaria caused by Plasmodium ovale spp. has been neglected by and large from research and has received only little scientific attention during the past decades. Ovale malaria is considered to feature relapses by liver hypnozoites although scientific evidence for this paradigm is scarce. CASE PRESENTATION: Here, the case of a 16-year-old male, who presented with fevers to the outpatient department in Vienna, Austria, after travelling to Uganda and Papua New Guinea is described...

Vector-borne diseases are a major concern for human health globally, especially malaria in densely populated, less developed, tropical regions of the world. Malaria causes loss of human life and economic harm, and may spread through travelers to new regions. Though there are sufficient therapeutics available for the effective treatment and cure of malaria, it infects millions of people and claims several thousand lives every year. Early diagnosis of the infection can potentially prevent the spread of disease, save lives, and mitigate the financial impact...

Millions of children travel annually, whether they are refugees, international adoptees, visitors, or vacationers. Although most young travelers do well, many develop a febrile illness during or shortly after their trips. Approaching a fever in the returning traveler requires an appropriate index of suspicion to diagnose and treat in a timely manner. As many as 34% of patients with recent travel history are diagnosed with routine infections, but serious infections such as malaria, enteric fever, and dengue fever should be on the differential diagnosis due the high morbidity and mortality in children...

Malarial infections are uncommon in the United States and almost all reported cases stem from recent travelers coming from endemic countries. Cerebral malaria (CM) is a severe form of the disease usually affecting children and individuals with limited immunity. Despite proper management, mortality from CM can reach up to 25%, especially when it is associated with brain edema. Inefficient management of the edema may result in brain herniation and death. Uniform guidelines for management of CM-associated brain edema are lacking...

Recently, five cases of malaria were reported in Italy. These people had not travelled abroad, prompting some media and political organizations to fuel a climate of fear by connecting the cases with migrants coming into the country. Here, we discuss scientific data highlighting the limited risk of malaria reintroduction in Italy.

Plasmodium vivax parasites have a unique dormant stage that can cause relapses weeks or months after the initial infection. These dormant parasites are among the main challenges of vivax malaria control as they constitute a reservoir that is difficult to eliminate. Since field studies are confounded by reinfections and possible recrudescence of drug-resistant parasites, most analyses of P. vivax relapses have focused on travelers returning from regions of malaria endemicity. However, it is not clear whether these individuals accurately recapitulate the relapse patterns of repeatedly infected individuals residing in areas of endemicity...
