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.

• Congenital chikungunya in a neonate with early-onset sepsis and petechiae: An unusual case report Fri, 27 Jan 2023 06:00:00 -0500
  Chikungunya, a mosquito-borne disease, is posing threat to neonatal population in Cambodia because of its challenging diagnosis and insufficient attention compared with Dengue. In what follows, we present a case of serologically-confirmed congenital chikungunya in a newborn presenting early-onset sepsis, and the mother was underdiagnosed with intrapartum flu-like infection.
• The research progress of Chikungunya fever Thu, 26 Jan 2023 06:00:00 -0500
  Chikungunya fever, an acute infectious disease caused by Chikungunya virus (CHIKV), is transmitted by Aedes aegypti mosquitoes, with fever, rash, and joint pain as the main features. 1952, the first outbreak of Chikungunya fever was in Tanzania, Africa, and the virus was isolated in 1953. The epidemic has expanded from Africa to South Asia, the Indian Ocean islands and the Americas, and is now present in more than 100 countries and territories worldwide, causing approximately 1 million...
• Identification of mosquito proteins that differentially interact with alphavirus nonstructural protein 3, a determinant of vector specificity Wed, 25 Jan 2023 06:00:00 -0500
  Chikungunya virus (CHIKV) and the closely related onyong-nyong virus (ONNV) are arthritogenic arboviruses that have caused significant, often debilitating, disease in millions of people. However, despite their kinship, they are vectored by different mosquito subfamilies that diverged 180 million years ago (anopheline versus culicine subfamilies). Previous work indicated that the nonstructural protein 3 (nsP3) of these alphaviruses was partially responsible for this vector specificity. To better...
• Dengue, chikungunya and Zika virus infections among Dutch travellers to Suriname: a prospective study during the introduction of chikungunya and Zika virus, 2014 to 2017 Wed, 25 Jan 2023 06:00:00 -0500
  BackgroundSuriname, a country endemic for dengue virus (DENV), is a popular destination for Dutch travellers visiting friends and relatives and tourist travellers. Chikungunya and Zika virus (CHIKV, ZIKV) were introduced in 2014 and 2015, respectively. Data on infection risks among travellers are limited.AimWe aimed to prospectively study incidence rate (IR) and determinants for DENV, ZIKV and CHIKV infection in adult travellers to Suriname from 2014 through 2017.MethodsParticipants kept a...
• Chronic Bilateral Symmetric Anterior Shoulder Dislocation Secondary to Seizures in Chikungunya Encephalitis Wed, 25 Jan 2023 06:00:00 -0500
  Bilateral shoulder dislocations are a rare occurrence and can be categorized as either symmetric (both humeral heads dislocate in the same direction) or asymmetric (wherein the humeral heads dislocate in different directions). Shoulder dislocations may be overlooked if they are the result of systemic injury; if diagnosed >21 days after occurring, they are considered chronic dislocations. We describe the case of a 31-year-old male who presented with an eight-week history of bilateral shoulder...
• Evaluation of Aedes aegypti Penetration, Probing, and Feeding Times on Mice Mon, 23 Jan 2023 06:00:00 -0500
  In mosquitoes, the intradermal search for vertebrate blood (probing time) corresponds to the time taken from initial insertion of the mouthparts in the skin until visualization of the initial engorgement of blood in the midgut. Probing time evaluation provides useful information on the ability of a mosquito to initiate successful blood feeding. In this protocol, we describe how to determine feeding parameters in Aedes aegypti, a widely distributed mosquito that transmits several deadly...
• A comparative analysis of Aedes albopictus and Aedes aegypti subjected to diapause-inducing conditions reveals conserved and divergent aspects associated with diapause, as well as novel genes associated with its onset Mon, 23 Jan 2023 06:00:00 -0500
  Aedes albopictus and Aedes aegypti are mosquito species that are distributed worldwide and transmit diverse arboviruses of medical importance, such as those causing yellow fever, dengue, chikungunya and Zika. A. albopictus embryos may remain viable for long periods in the environment due to their ability to become dormant through quiescence or diapause, a feature that contributes to their dispersion and hinders control actions. Diapause incidence can vary among natural populations of A....
• Pupal productivity of larval habitats of Aedes aegypti in Msambweni, Kwale County, Kenya Sun, 22 Jan 2023 06:00:00 -0500
  Aedes aegypti is an important vector of several arboviruses including dengue and chikungunya viruses. Accurate identification of larval habitats of Ae. aegypti is considered an essential step in targeted control. This study determined Ae. aegypti productivity in selected larval habitats in Msambweni, Kwale County, Kenya. Three sequential larval habitat surveys were conducted. The first survey was habitat census (baseline) through which 83 representative larval habitats were identified and...
• Rapid Diagnostic Tests for the Detection of the Four Dengue Virus Serotypes in Clinically Relevant Matrices Sun, 22 Jan 2023 06:00:00 -0500
  The efficient and accurate diagnosis of dengue, a major mosquito-borne disease, is of primary importance for clinical care, surveillance, and outbreak control. The identification of specific dengue virus serotype 1 (DENV-1) to DENV-4 can help in understanding the transmission dynamics and spread of dengue disease. The four rapid low-resource serotype-specific dengue tests use a simple sample preparation reagent followed by reverse transcription-isothermal recombinase polymerase amplification...
