Background: Beyond the acute illness phase, chikungunya constitutes a public health problem given its chronic disease phase, which may include long-term arthralgia, arthritis, fatigue, and depression. Currently, there is no consensus on how to define chikungunya chronicity. Methods: A comprehensive cross-sectional survey was performed in Curaçao in June and July 2015 to evaluate 304 adult laboratory-confirmed chikungunya patients 3-16 months after diagnosis. We developed a novel tool, the Curaçao Long-Term Chikungunya Sequelae (CLTCS) score, to classify chronic chikungunya disease and estimate its burden regarding disease duration, clinical presentation, and impact on quality of life...

Background: Travellers are at risk of acquiring infectious diseases during travel, with risks differing by destination, travel and traveller characteristics. A pre-travel health consultation may minimize this risk. However, uptake of pre-travel health advice remains low. We investigated pre-travel health preparations and disease-specific risk behaviours among notified cases of selected travel-associated infectious diseases imported into Australia. Methods: Prospective enhanced surveillance of notified cases of typhoid, paratyphoid, measles, hepatitis A, hepatitis E, malaria and chikungunya was conducted in two Australian states between February 2013 and January 2014...

We investigated an outbreak of exanthematous illness in Maceió by using molecular surveillance; 76% of samples tested positive for chikungunya virus. Genetic analysis of 23 newly generated genomes identified the East/Central/South African genotype, suggesting that this lineage has persisted since mid-2014 in Brazil and may spread in the Americas and beyond.

We isolated East/Central/South African genotype chikungunya virus during the 2016 epidemic in Rio de Janeiro, Brazil. Genome sequencing revealed unique mutations in the nonstructural protein 4 (NSP4-A481D) and envelope protein 1 (E1-K211T). Moreover, all Brazil East/Central/South isolates shared the exclusive mutations E1-M407L and E2-A103T.

The possibility of the rapid and global spread of Zika, chikungunya, yellow fever, and dengue fever by Aedes albopictus is well documented and may be facilitated by changes in climate. To avert and manage health risks, climatic and topographic information can be used to model and forecast which areas may be most prone to the establishment of Ae. albopictus. We aimed to weigh and prioritize the predictive value of various meteorological and climatic variables on distributions of Ae. albopictus in south-eastern Iran using the Analytical Hierarchy Process...

BACKGROUND: Aedes aegypti and Ae. albopictus are two highly invasive mosquito species, both vectors of several viruses, including dengue, chikungunya and Zika. While Ae. aegypti is the primary vector in the tropics and sub-tropics, Ae. albopictus is increasingly under the public health watch as it has been implicated in arbovirus-transmission in more temperate regions, including continental Europe. Vector control using insecticides is the pillar of most control programmes; hence development of insecticide resistance is of great concern...

BACKGROUND: As the arboviral diseases dengue, chikungunya and Zika emerge in the Americas, so does the need for sustainable vector control policies. To successfully achieve mosquito control, joint efforts of both communities and governments are essential. This study investigates this important, but by-and-large neglected topic. METHODS: In June and July 2015, a cross-sectional mixed methods study applying a survey questionnaire (response rate of 82.5%; n = 339), in-depth interviews (n = 20) and focus group discussions (n = 7; 50 participants) was performed in Curaçao...

Background Chikungunya fever is a pandemic disease caused by an arthropod-borne chikungunya virus (CHIKV). The virus spreads through mosquitoes. This mosquito induced viral illness is clinically suspected on symptoms from fever and severe polyarthralgia. The recent outbreak of chikungunya was reported in November 2016 in the metropolitan city Karachi, Pakistan. We emphasis on the awareness of the etiology and vector control to prevent serious consequences. Method A total number of 1275 patients were included in this cross-sectional study...

BACKGROUND: The emergence of Zika virus (ZIKV) presents new challenges to both clinicians and public health authorities. Overlapping clinical features between the diseases caused by ZIKV, dengue (DENV) and chikungunya (CHIKV) and the lack of validated serological assays for ZIKV make accurate diagnosis difficult. Brazilian authorities largely rely on clinical and epidemiological data for the epidemiological and clinical classifications of most ZIKV cases. OBJECTIVE: To report the laboratory and clinical profiles of patients diagnosed with Zika fever based only on clinical and epidemiological data...

Genital aphthous ulcers can result from multiple conditions including febrile syndromes. Chikungunya infection manifests mainly as fever accompanied by polyarthralgia and pruritic rash. Nevertheless, healthcare providers should be alert to additional presentations. This is the case of a young woman presenting with painful genital ulcers after a three day prodome of fever and polyarthralgia. As a suspected case of Chikungunya infection and a clinical diagnosis of aphthae, treatment with oral prednisone for two weeks produced complete resolution of ulcers with no scarring...

The rise of mosquito's transmitted diseases, like dengue, zika and chikungunya in Brazil in the last years has increased the concerns on protection against mosquito's bites. However, the prohibitive prices of the commercially available repellents for the majority of the Brazilian population, has provoked a search for cheaper solutions, like the use of the homemade ethanolic extract of Indian clove (Syzygium aromaticum L.) as repellent, which has been reported as quite efficient by the local press. In order to verify this, we performed here, the quantification of the main components of this extract through high-performance thin-layer chromatography (HPTLC)-densitometry and evaluated its efficiency as repellent, as well as the acetylcholinesterase (AChE) inhibition capacity...

Dengue and chikungunya fevers are transmitted by the common mosquito vector Aedes and malaria by Anopheles. Concurrent infections are reported due to co-circulation of these pathogens, especially in endemic regions. We report a rare case of triple infection with 3 arthropod-borne pathogens (Plasmodium vivax and the dengue and chikungunya viruses) in a 3-year-old child from New Delhi, India, in August 2016. The viruses were identified by RT-PCR and the parasite by microscopy and antigen detection. The dengue virus serotype 3 sequence was clustered in the genotype III by the phylogenetic analysis...

Chikungunya virus (CHIKV), a member of Alphavirus genus, is responsible for chikungunya fever (CHIKF), which is characterized by the presence of fever, rash, myalgia, and arthralgia. Reemergence of CHIKV has become a significant public health concern in Asian and African countries and is newly emerging in the Middle East, Pacific, American, and European countries. Cytokines, innate (monocytes, natural killer cells) and adaptive immune response (role of B cells and T cells i.e. CD4(+) and CD8(+)), and/or viral factors contribute to CHIKV-induced arthritis...

Identifying etiologies of acute febrile illnesses (AFI) is challenging due to non-specific presentation and limited availability of diagnostics. Prospective AFI studies provide a methodology to describe the syndrome by age and etiology, findings that can be used to develop case definitions and multiplexed diagnostics to optimize management. We conducted a 3-year prospective AFI study in Puerto Rico. Patients with fever ≤7 days were offered enrollment, and clinical data and specimens were collected at enrollment and upon discharge or follow-up...

In early 2016, it was suspected that there were more deaths in Pernambuco than in previous years during an epidemic of chikungunya. This study tested whether there was an increased number of deaths and, if so, whether this increase could be related to a chikungunya epidemic. Indeed, there was an increase of 4235 deaths in 2016 compared to the average of the four previous years, and the highest differences were found during the peak period of the epidemic. It was evident that not all of these deaths could be attributed to complications of chikungunya...

Understanding the ability of the chikungunya virus (CHIKV) to be transmitted by Aedes vectors in the Americas is critical for assessing epidemiological risk. One element that must be considered is the minimum infectious dose of virus that can lead to transmission following the extrinsic incubation period. This study aimed to determine the minimum infection rate for the two Aedes species studied. The results revealed that doses as low as 3.9 log10 plaque-forming units per mL (pfu/mL) of an Asian genotype CHIKV strain can lead to transmission by Ae...
