Chikungunya Virus Net is the web resource for anyone interested in chikungunya. Chikungunya virus (CHIKV) is an insect-borne virus, of the genus Alphavirus, that is spread by Aedes mosquitoes. Chikungunya infection causes fever and severe joint pain. Other symptoms include muscle pain, headache, nausea, fatigue and rash. The disease shares some clinical signs with dengue, and can be misdiagnosed in areas where dengue is common. There have been recent breakouts of chikungunya in Africa, Asia and the Indian subcontinent. In recent decades mosquito vectors of chikungunya have spread to Europe and the Americas. In 2007, disease transmission was reported for the first time in Europe. There is no cure for the disease. Treatment is focused on relieving the symptoms.

The objectives of Chikungunya Virus Net are to be the public and professional information resource for chikungunya and to serve as a network in the exchange of information and news related to chikungunya.

  Rift Valley Fever -- Sudan
  Doctors in Sudan's Northern State have reported 27 deaths and 68 [abortions] among livestock in the area of El Nafaab in Merowe locality and warn of the emergence of cases of Rift Valley fever [RVF] and chikungunya, similar to last year [2020]. They have appealed to the Ministry of Health and the state government to deal with the potential epidemic in a safe manner.

• Effectiveness of environmental interventions to reduce entomological indices of dengue, Zika, and chikungunya vector Sun, 22 May 2022 06:00:00 -0400
  Vector-borne diseases are a major public health problem. Among them, dengue, Zika and chikungunya illnesses are increasing their incidence and geographical expansion. Since vector control is the main measure to prevent these diseases, this systematic review aims to determine the effectiveness of environmental interventions for the prevention of the transmission of these three diseases, as well as for the reduction of their burden. Experimental studies of environmental management interventions...
• Child Neurology Care in Latin America: Challenges and Potential Solutions Sun, 22 May 2022 06:00:00 -0400
  CONCLUSIONS: The virtual platforms such as Zoom, expanded during the COVID-19 pandemic, are useful not only to improve access to care through telemedicine but also for educational purposes. Collaborative efforts to support educational courses and symposia in Spanish are ongoing. It is necessary to set short- and long-term priorities to improve child neurology care in the region. Immediate priorities should focus on improving the diagnosis of neurological conditions, making emphasis on locally...
• Ultrasound-assisted nanoemulsion of Trachyspermum ammi essential oil and its constituent thymol on toxicity and biochemical aspect of Aedes aegypti Fri, 20 May 2022 06:00:00 -0400
  Aedes aegypti is the main vector of yellow fever, chikungunya, Zika, and dengue worldwide and is managed by using chemical insecticides. Though effective, their indiscriminate use brings in associated problems on safety to non-target and the environment. This supports the use of plant-based essential oil (EO) formulations as they are safe to use with limited effect on non-target organisms. Quick volatility and degradation of EO are a hurdle in its use; the present study attempts to develop...
• Evidence for serial founder events during the colonization of North America by the yellow fever mosquito, Aedes aegypti Fri, 20 May 2022 06:00:00 -0400
  The Aedes aegypti mosquito first invaded the Americas about 500 years ago and today is a widely distributed invasive species and the primary vector for viruses causing dengue, chikungunya, Zika, and yellow fever. Here, we test the hypothesis that the North American colonization by Ae. aegypti occurred via a series of founder events. We present findings on genetic diversity, structure, and demographic history using data from 70 Ae. aegypti populations in North America that were genotyped at 12...
• Predation of Aedes aegypti Eggs By Foraging Ants Solenopsis invicta, Myrmicaria brunnea, Diacamma rugosum, and Monomorium minimum Thu, 19 May 2022 06:00:00 -0400
  The diseases transmitted by Aedes mosquitoes, such as dengue, chikungunya, yellow fever, and Zika, are ever-increasing. Rapid and unplanned urbanization adversely impacts various endemic species such as ants and facilitates the breeding of Aedes mosquitoes. We have observed the predatory potential of ants over Aedes eggs in urban breeding habitats, and their impact on Aedes mosquito breeding was determined by a field experiment that mimicked the natural breeding habitats. It was found that 99.4%...
• A Cross-Sectional Household Survey in the US Virgin Islands (2019) Reveals Cisterns as Challenging Peridomestic Aedes aegypti Habitats Thu, 19 May 2022 06:00:00 -0400
  Most residences in the United States Virgin Islands (USVI) rely on household rainwater-catchment systems and subterranean cisterns for long-term water storage that may provide suitable habitats for mosquitoes of public health relevance. We conducted a household cistern survey (n = 164) on the islands of St. Croix, St. John, and St. Thomas in 2019. The survey revealed that 45.7% (95% CI: 38.3-53.4%) of cisterns contained mosquitoes (adult and/or immature mosquitoes). Aedes aegypti, a vector of...
• Climate Change and Cascading Risks from Infectious Disease Wed, 18 May 2022 06:00:00 -0400
  Climate change is adversely affecting the burden of infectious disease throughout the world, which is a health security threat. Climate-sensitive infectious disease includes vector-borne diseases such as malaria, whose transmission potential is expected to increase because of enhanced climatic suitability for the mosquito vector in Asia, sub-Saharan Africa, and South America. Climatic suitability for the mosquitoes that can carry dengue, Zika, and chikungunya is also likely to increase,...
• Description of the mitogenome and phylogeny of Aedes spp. (Diptera: Culicidae) from the Amazon region Wed, 18 May 2022 06:00:00 -0400
  The genus Aedes (Diptera: Culicidae) includes species of great epidemiological relevance, particularly involved in transmission cycles of leading arboviruses in the Brazilian Amazon region, such as the Zika virus (ZIKV), Dengue virus (DENV), Yellow fever virus (YFV), and Chikungunya virus (CHIKV). We report here the first putatively complete sequencing of the mitochondrial genomes of Brazilian populations of the species Aedes albopictus, Aedes scapularis and Aedes serratus. The sequences...
• Comodulation of Dengue and Chikungunya Virus Infection During a Coinfection Scenario in Human Cell Lines Mon, 16 May 2022 06:00:00 -0400
  The Dengue virus (DENV) and Chikungunya virus (CHIKV) are the arboviruses that pose a threat to global public health. Coinfection and antibody-dependent enhancement are major areas of concern during DENV and CHIKV infections, which can alter the clinical severity. Acute hepatic illness is a common manifestation and major sign of disease severity upon infection with either dengue or chikungunya. Hence, in this study, we characterized the coexistence and interaction between both the viruses in...
• Highly potent multivalent VHH antibodies against Chikungunya isolated from an alpaca naïve phage display library Sun, 15 May 2022 06:00:00 -0400
  CONCLUSIONS: Compared to monovalent antibodies, multivalent VHH antibodies Nb-2E8 and Nb-3C5 showed high affinity and are potential candidates for diagnostic applications to better detect CHIKV virions in sera.
