Dengue, Zika and Chikungunya are emerging arboviruses and important causes of acute febrile disease in tropical areas. Although dengue does not represent a new condition, a geographic expansion over time has occurred with the appearance of severe neurological complications. Neglect has allowed the propagation of the vector (Aedes spp), which is also responsible for the transmission of other infections such as Zika and Chikungunya throughout the world. The increased number of infected individuals has contributed to the rise of neurological manifestations including encephalitis, myelitis, meningitis, Guillain-Barré syndrome and congenital malformations such as microcephaly...

INTRODUCTION: Mathematical models and field data suggest that human mobility is an important driver for Dengue virus transmission. Nonetheless little is known on this matter due the lack of instruments for precise mobility quantification and study design difficulties. MATERIALS AND METHODS: We carried out a cohort-nested, case-control study with 126 individuals (42 cases, 42 intradomestic controls and 42 population controls) with the goal of describing human mobility patterns of recently Dengue virus-infected subjects, and comparing them with those of non-infected subjects living in an urban endemic locality...

BACKGROUND: In a new influenza pandemic, travel data such as arrival times of cases seeded by the originating country can be regarded as a combination of the epidemic size and the mobility networks of infections connecting the originating country with other regions. It can be a complete and timely source for estimating the basic reproduction number (R 0 ), a key indicator of disease transmissibility. METHOD: In this study, we developed a likelihood-based method using arrival times of infected cases in different countries to estimate R 0 for influenza pandemics...

We describe a case of intermediate leptospirosis resulting from Leptospira licerasiae infection in a traveler returning to Japan from Brazil. Intermediate leptospirosis should be included in the differential diagnosis for travelers with fever returning from South America. This case highlights the need for strategies that detect pathogenic and intermediate Leptospira species.

PURPOSE OF REVIEW: The purpose of this article is to review what is currently known about Zika virus (ZIKV) disease and associated neurologic complications. RECENT FINDINGS: ZIKV is a mosquito-borne or sexually transmitted flavivirus rapidly spreading throughout the Americas. While ZIKV infection is usually asymptomatic, it may cause a non-specific illness with fever, rash, myalgia, headache, and/or non-purulent conjunctivitis. Additionally, ZIKV has been associated with a number of neurologic complications including microcephaly and other birth defects, Guillain-Barré syndrome, meningoencephalitis, myelitis, and various ophthalmologic abnormalities...

Spiroplasma eriocheiris is a pathogen that causes mass mortality in Chinese mitten crab, Eriocheir sinensis. S. eriocheiris causes tremor disease and infects almost all of the artificial breeding crustaceans, resulting in disastrous effects on the aquaculture economy in China. S. eriocheiris is a wall-less helical bacterium, measuring 2.0 to 10.0 μm long, and can swim up to 5 μm per second in a viscous medium without flagella by switching the cell helicity at a kink traveling from the front to the tail. In this study, we showed that S...

BACKGROUND: Asplenic patients are at risk for severe infections, but adherence to recommended preventive education and vaccination is poor. The goal of this study was to demonstrate that a targeted intervention can improve vaccination rates in a population of asplenic veterans. METHODS: Surgically asplenic patients actively receiving care in our health care system were identified via a database search. Patients were contacted via mailed letters and encouraged to attend an existing travel clinic with a new process designed for asplenic patients...

OBJECTIVE: The aim was to analyse those syndromes without fever in travellers who return from tropical regions evaluated at our Department of Infectology and Tropical Medicine. Clarifying these conditions intends to reach earlier diagnoses and, perhaps, to avoid the emergence and spread of imported diseases, as well as to establish appropriate preventive measures. METHODS: An observational descriptive transversal study was performed, selecting those patients who returned from tropical regions without fever (n = 281), amongst all travellers evaluated in our department between 1998 and 2013...

The World Health Organization (WHO) recommends that people travelling to or living in areas with Zika virus (ZIKV) outbreaks or epidemics adopt prophylactic measures to reduce or eliminate mosquito bites, including the use of insect repellents. It is, however, unknown whether repellents are effective against ZIKV-infected mosquitoes, in part because of the ethical concerns related to exposing a human subject's arm to infected mosquitoes in the standard arm-in-cage assay. We used a previously developed, human subject-free behavioural assay, which mimics a human subject to evaluate the top two recommended insect repellents...

We present a rare case of primary tuberculous tenosynovitis in a young patient with an acute history of non-penetrating traumatic injury. The patient had recently visited Pakistan and presented with sudden onset pain at the base of their right fifth digit after trying to catch a cricket ball. A provisional diagnosis of haematoma was made; however, ultrasonography revealed a mass attached to the A2 pulley. Surgical excision followed by histological examination and culture identified Mycobacterium Tuberculosis infection...

Flaviviruses represent a global public health concern. They consist of ∼70 viruses with almost half of them causing human diseases with unspecified febrile illnesses. Cities in western Saudi Arabia are endemic for viruses (DENV) with sporadic infections due to Alkhumra hemorrhagic fever virus (AHFV). They also represent a major destination for travelers coming for annual religious pilgrimages (Hajj and Umrah) from all over the world. However, whether other flaviviruses are circulating is not known because of the limited number of surveillance studies...

Due to the open policy of the Chinese government, a large number of Burmese individuals enter China at land ports in Yunnan province for travel or business. However, the situation of HIV-1 infection and its phylogenetic characteristics among these travelers remains unclear, which is a potential threat to public health. From January 2003 to December 2012, a total of 1,961 travelers were detected to be positive for HIV-1 infection at land ports between Myanmar and Yunnan province, China. From 1153 (58.8%) Burmese of them, we randomly collected 489 serum samples for HIV-1 subtype/recombinant analysis...

Skin infections account for a significant subset of dermatologic conditions of childhood. Common cutaneous viral infections in children include warts, molluscum contagiosum, hand-foot-and-mouth disease, and herpes simplex. Although viral infections are self-limited and often only mildly symptomatic, they can cause anxiety, embarrassment, and health care use. Recognition of their common and atypical presentations is necessary to differentiate them from other skin conditions of similar morphology. Impetigo, cellulitis, and abscess comprise the majority of childhood bacterial skin infections and are treated with topical or systemic antibiotics that cover group A Streptococcus and Staphylococcus aureus...

Children who are adopted internationally have an increased risk of infectious diseases due to endemic conditions and variable access to preventive health care, such as vaccines, in their country of origin. Pediatricians and other providers who care for children should be familiar with the recommended screening for newly arrived international adoptees. Testing for gastrointestinal pathogens, tuberculosis, hepatitis, syphilis, and HIV should be routinely performed. Other endemic diseases and common skin infections may need to be assessed...

The global invasion of West Nile virus, chikungunya virus and Zika virus in the past two decades suggests an increasing rate of mosquito-borne virus (arbovirus) dispersal. Rift Valley fever virus (RVFV) is an arbovirus identified as a high-consequence threat to the United States (USA) because of the severe economic and health consequences associated with disease. Numerous studies demonstrate that the USA is receptive to RVFV transmission based on the widespread presence of competent mosquito species and vertebrate species...

There is limited information on the risks and healthcare requirements of patients with cystic fibrosis (CF) undertaking travel abroad. Of 100 patients (mean age 24.7 years, mean FEV1 57.3 %predicted) attending a UK adult CF Centre, 96% had travelled abroad but 14% now limited travel on medical advice. They travelled frequently and widely, often undertaking adventurous activities on holidays, but because of the costs involved, 18% travelled without travel insurance and 23% with insurance which did not cover CF...
