BACKGROUND: Dengue (DV), chikungunya (CV) and Zika virus (ZV) infections are rapidly expanding across countries and diagnosed in returned travelers who represent epidemiological sentinels. French Territories of America (FTA) such as Guadeloupe and Martinique are highly touristic places and have experienced three consecutive outbreaks by such viruses in the last decade. OBJECTIVE: We evaluated how ill returned travelers could be deemed as epidemiological sentinels for these three expanding arboviral diseases during eight consecutive years...

Over the past decade, the number of international travels has increased. Hence, the risk of transmission of parasitic diseases has also increased. One of the risk infections is malaria; Plasmodium vivax and P. falciparum species can be transmitted. The distribution of leishmaniasis cases has been reported from the south of USA to the north of Argentina. Approximately 57,000 cases of cutaneous and mucocutaneous leishmaniasis occur annually, and approximately 4000 visceral leishmaniasis cases are observed. It is reported that Chagas disease is endemic in 21 countries, and approximately 6 million people are affected every year...

The most common types of malaria in the world are Plasmodium vivax and P. falciparum. In countries where both species are endemic, P. vivax and P. falciparum coinfection also occurs. Thus, the possibility of mixed malaria in Turkey should always be considered in cases with a traveling history to these countries. Here, we report a case of P. vivax/P. falciparum mixed infection that was diagnosed as P. falciparum malaria in Ethiopia. However, the administered treatment was inadequate, and infection recurred because of the miss in the diagnosis of P...

Travel is important in the spread of diseases, and the number of travelers is increasing daily. Therefore, the importance of the diseases that occur during or after travel is increasing. In underdeveloped countries in particular, parasitic diseases are epidemic or endemic, and these diseases lead to high numbers of deaths. People traveling from developed to underdeveloped countries have a higher risk of transmission of parasitic diseases during travel. Fifteen percent of the world's population lives in Africa...

BACKGROUND: Human African trypanosomiasis (HAT) is one of the most complex parasitic diseases known to humankind. It usually occurs in endemic areas in Africa, but is occasionally detected in returning travelers and migrants in non-endemic countries. CASE PRESENTATION: In August 2017, a case of HAT was diagnosed in China in a traveler returning from the Masai Mara area in Kenya and the Serengeti area in Tanzania. The traveler visited Africa from 23 July to 5 August, 2017...

BACKGROUND: Mycobacterium bovis causing tuberculosis in animals is responsible for zoonotic tuberculosis in patients. Veterinary control measures and milk pasteurization has led to a significant decrease in human cases of M. bovis infections in developed countries. CASE PRESENTATION: We diagnosed recurrent M. bovis epididymitis in a 63-year old Caucasian man without any signs of pulmonary or disseminated disease. Relevant epidemiological expositions included camel milk drinking during prolonged travels in Niger, prior to initial clinical manifestations...

Hepatitis E virus (HEV) is a common cause of acute viral hepatitis. Virus genotypes 1 and 2 infect humans in developing countries by the fecal-oral route. To assess attack rates and disease incidence for travelers, we prospectively studied 604 long-term travelers to subtropical and tropical countries. Participants donated blood samples pretravel and posttravel and kept a diary. A total of 89/604 (15%) pretravel samples were positive for HEV IgG by ELISA, suggesting previous HEV infection. Seroconversion for HEV was found for 19/515 travelers (attack rate 3...

After the waves of reported cases of infection with Zika virus swept across the Americas in 2015-16, the overall transmission of the virus in the Western Hemisphere declined in 2017. Between June 8 and August 31, 2017, only 16 new cases of Zika virus infection, all travel-related, were reported in Canada. This represents an 88% reduction in the cases recorded during the same time frame in 2016. Herd immunity undoubtedly constrains the transmission of the virus in endemic regions. However, while most countries in the Americas are no longer observing continuous transmission in the form of sustained increases over time, some areas are experiencing a notable resurgence...

As of May 23, 2017, 29 cases of a new Escherichia coli O121 infection have been identified in six provinces (Alberta, British Columbia, Newfoundland and Labrador, Ontario, Quebec and Saskatchewan) linked with the consumption of uncooked flour. One additional case was identified in a U.S. resident who traveled to Canada during the exposure period. Patients' ages ranged from 2-79 years (median = 23.5 years) and 50% were female. Eight patients were hospitalized, and one developed hemolytic uremic syndrome. Because of the recent emergence of E...

We identified a case of acute Hepatitis A virus (HAV) infection linked to cannabis use. The local Public Health department received report of a man in his mid-20s with a classic presentation of hepatitis - jaundice, abdominal pain, vomiting, general malaise, and dark urine - as well as elevated serum aminotransferase levels and a positive anti-HAV IgM. Upon questioning, he reported no contact with ill individuals, or travel outside his metropolitan area. His exclusive source of water was the local municipal supply...

Providing advice for travelers embarking on long-term trips poses a challenge in travel medicine. A long duration of risk exposure is associated with underuse of protective measures and poor adherence to chemoprophylaxis, increasing the chances of acquiring infections. Recently, in our clinic, we observed an increase in the number of travelers undertaking round-the-world trips. These individuals are typically aged around 32 years and quit their jobs to embark on one-to-two-year journeys. Their destinations include countries in two or more continents, invariably Southeast Asia and Indonesia, and mostly involve land travel and visiting rural areas...

Background: In May 2012, the New Hampshire (NH) Division of Public Health Services (DPHS) was notified of 4 persons with newly diagnosed hepatitis C virus (HCV) infection at hospital X. Initial investigation suggested a common link to the hospital cardiac catheterization laboratory (CCL) because the infected persons included 3 CCL patients and a CCL technician. NH DPHS initiated an investigation to determine the source and control the outbreak. Methods: NH DPHS conducted site visits, case patient and employee interviews, medical record and medication use review, and employee and patient HCV testing using enzyme immunoassay for anti-HCV, reverse-transcription polymerase chain reaction for HCV RNA, nonstructural 5B (NS5B) and hypervariable region 1 (HVR1) sequencing, and quasispecies analysis...

BACKGROUND: Q fever is a zoonotic disease caused by Coxiella burnetii. This bacterium survives harsh conditions and attaches to dust, suggesting environmental dispersal is a risk factor for outbreaks. Spatial epidemiology studies collating evidence on Q fever geographical contamination gradients are needed, as human cases without occupational exposure are increasing worldwide. METHODS: We used a systematic literature search to assess the role of distance from ruminant holdings as a risk factor for human Q fever outbreaks...

Leptospirosis is a potentially fatal emerging zoonosis with worldwide distribution and a broad range of clinical presentations and exposure risks. It typically affects vulnerable populations in (sub)tropical countries but is increasingly reported in travelers as well. Diagnostic methods are cumbersome and require further improvement. Here, we describe leptospirosis among travelers presenting to the GeoSentinel Global Surveillance Network. We performed a descriptive analysis of leptospirosis cases reported in GeoSentinel from January 1997 through December 2016...

The European Bone and Joint Infection Society (EBJIS) was founded by a French initiative as a Study Group in 1982. The group of 26 founding members increased to around 60 members in 1992, and membership was limited to surgeons from Europe, experienced in orthopedic infections. In 1993, a transformation to a Society was performed with a more open structure for all kind of doctors and scientists. Annual meetings, a Travelling Fellowship, research projects and instructional courses were organized. Professional support and improved publicity has resulted in an increase to more than 400 members, from worldwide...

Lymphatic vessels remove and transport excess interstitial fluid to lymph nodes (LNs) for fluid balance and immune protection. LNs are typically surrounded by perinodal adipose tissue (PAT). However, PAT is a blood vessel-rich but lymphatic-rare tissue; therefore, how excess fluid in PAT is removed remains unclear. Using C57BL/6 mice, fluorescent dye tracing and transmission electron microscopy results suggest that fluid in PAT can travel to the LN via collagen I+ channels (PAT-LN conduits), merge into a collagen-rich space between the PAT and LN capsule (PAT-LN sinus), and may enter the LN via the LN capsule-associated conduits...

Background: Tuberculosis (TB) in children is often an indicator of recent transmission. Genotyping and whole genome sequencing (WGS) can enhance pediatric TB investigations by confirming or refuting transmission events. Methods: Mycobacterium tuberculosis isolates from all pediatric patients <18 years with culture-confirmed TB in British Columbia (BC) from 2005-2014 (n=49) were genotyped by MIRU-VNTR and compared to adult isolates. Genotypically clustered cases underwent WGS...
