Zika fever is an acute infectious disease caused by the Zika virus (ZIKV), an RNA virus belonging to the genus Flavivirus. ZIKV can be transmitted by bites from Aedes aegypti and Aedes albopictus species, sexual activity, blood transfusion and from mother to fetus during pregnancy and delivery. A total of 50 territories and countries in the Americas had reported ZIKV infections. For those with symptoms, the presentation is similar to dengue fever with body aches, joint pain, fatigue, malaise, fever and conjunctivitis lasting up to seven days...

There are many infectious diseases that can be spread by daily commuting of people and dengue fever is one of them. The absence of vaccine and irregularities in ongoing vector control programs make this disease the most frequent and persistent in many tropical and subtropical regions of the world. This paper targets to access the effects of daily commuting on dengue transmission dynamics by using a deterministic two-patch model fitted to observed data gathered in Cali, Colombia where dengue fever is highly persistent and exhibits endemo-epidemic patterns...

The Zika fever is an arboviral disease resulting from the infection with Zika virus (ZIKV). The virus is transmitted to humans by the bite of Aedes mosquitos, mainly Aedes aegypti and Aedes albopictus . ZIKV has been detected for decades in African and Asian regions and, since 2007, has spread to other continents; among them, infections are most reported in the Americas. This can be explained by the presence of vectors in highly populated and tropical regions where people are susceptible to contamination. ZIKV has been considered by the World Health Organization a serious public health problem because of the increasing number of cases of congenital malformation and neurological disorders related to its infection, such as microcephaly, Guillain⁻Barré syndrome, meningoencephalitis, and myelitis...

Background: Dengue fever is an important tropical infection causing significant mortality. The pathophysiology of hematological abnormalities in dengue remains poorly studied. In this study, we analyzed the hematological abnormalities by thromboelastography (TEG). Methods: This cross-sectional study evaluated complicated dengue patients with TEG. Thromboelastographic variables were categorized into six patterns: factor deficiency, platelet dysfunction, enzymatic hypercoagulability, combined enzymatic and platelet hypercoagulability, primary fibrinolysis, and secondary hyperfibrinolysis...

Mosquitoes are incriminated as vectors for many crippling diseases, including malaria, West Nile fever, Dengue fever, and other neglected tropical diseases (NTDs). microRNAs (miRNAs) can interact with multiple target genes to elicit biological functions in the mosquitoes. However, characterization and function of individual miRNAs and their potential targets have not been fully determined to date. We conducted a systematic review of published literature following PRISMA guidelines. We summarize the information about miRNAs in mosquitoes to better understand their metabolism, development, and responses to microorganisms...

BACKGROUND: Melioidosis is an emerging infection in the tropics caused by the bacterium Burkholderia pseudomallei. Poorly controlled diabetes is a known risk factor. Melioidosis has a broad spectrum of clinical manifestations ranging from a localized abscess to pneumonia to disseminated sepsis with multiorgan failure. Pyrexia of unknown origin is a common presentation. Abscesses in unusual anatomical locations are well known to be associated with melioidosis. CASE PRESENTATION: We report a case of a 64-year-old Sri Lankan Sinhalese man with prolonged fever and constitutional symptoms with a neglected swelling over the back of the scalp who was found to have an abscess in the subgaleal space of the scalp during surgical drainage...

Zika virus (ZIKV) is an emerging flavivirus rapidly spreading throughout the tropical Americas. Aedes mosquitoes is the principal way of transmission of the virus to humans. ZIKV can be spread by transplacental, perinatal, and body fluids. ZIKV infection is often asymptomatic and those with symptoms present minor illness after 3 to 12 days of incubation, characterized by a mild and self-limiting disease with low-grade fever, conjunctivitis, widespread pruritic maculopapular rash, arthralgia and myalgia. ZIKV has been linked to a number of central and peripheral nervous system injuries such as Guillain-Barré syndrome (GBS), transverse myelitis (TM), meningoencephalitis, ophthalmological manifestations, and other neurological complications...

Relapsing fever still remains a neglected disease and little is known on its reservoir, tick vector and physiopathology in the vertebrate host. The disease occurs in temperate as well as tropical countries. Relapsing fever borreliae are spirochaetes, members of the Borreliaceae family which also contain Lyme disease spirochaetes. They are mainly transmitted by Ornithodoros soft ticks, but some species are vectored by ixodid ticks. Traditionally a Borrelia species is associated with a specific vector in a particular geographical area...

The introduction and spread of West Nile virus and the recent introduction of chikungunya and Zika viruses into the Americas have raised concern about the potential for various tropical pathogens to become established in North America. A historical analysis of yellow fever and malaria incidences in the United States suggests that it is not merely a temperate climate that keeps these pathogens from becoming established. Instead, socioeconomic changes are the most likely explanation for why these pathogens essentially disappeared from the United States yet remain a problem in tropical areas...

Tropical infections form 20-30% of ICU admissions in tropical countries. Diarrheal diseases, malaria, dengue, typhoid, rickettsial diseases and leptospirosis are common causes of critical illness. Overlapping clinical features makes initial diagnosis challenging. A systematic approach involving (1) history of specific continent or country of travel, (2) exposure to specific environments (forests or farms, water sports, consumption of exotic foods), (3) incubation period, and (4) pattern of organ involvement and subtle differences in manifestations help in differential diagnosis and choice of initial empiric therapy...

Chikungunya is a mosquito-transmitted virus found primarily in Africa and Asia. In late 2013, chikungunya virus emerged in the Western hemisphere, spreading from the Caribbean to South, Central, and North America (MMWR Morb Mortal Wkly Rep. 2014;63:1121-1128). Symptoms can be similar to nonspecific viral presentations including fever, joint pain, joint swelling, and rash. The diagnosis of infectious tropical diseases in the emergency department often requires a high index of suspicion, given the nonspecific early findings that characterize many of these tropical diseases...

INTRODUCTION: Chikungunya (CHIK) is a tropical arbovirus, transmitted by the female mosquito Aedes aegypti and Aedes albopictus. In Brazil, there have been cases reported since 2014. The initial manifestations of this virus are sudden onset high fever, headache, chills, rashes, myalgia and intense joint pain. Usually, CHIK presents the acute and chronic phases, the latter characterized by bilateral polyarthralgia, which can last for months or even years. During this period, autoimmune diseases can be triggered, making the picture even more complicated...
