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.

  Yellow Fever, Zika virus, Chikungunya, Dengue -- United States
  The mosquito that carries yellow fever has been detected in Gridley near Highway 99 and East Gridley Rd, according to the Butte County Mosquito and Vector Control District. The _Aedes aegypti_ was found Monday [2 Aug 2021] in Gridley as it has also been found in Chico, Thermalito, and Oroville. Just like Thermalito, this is the first time the invasive species was detected in Gridley. It was found in Chico and Oroville for 2 years in a row.

• Epidemics of chikungunya, Zika, and COVID-19 reveal bias in case-based mapping Tue, 03 Aug 2021 06:00:00 -0400
  Explosive epidemics of chikungunya, Zika, and COVID-19 have recently occurred worldwide, all of which featured large proportions of subclinical infections. Spatial studies of infectious disease epidemics typically use symptomatic infections (cases) to estimate incidence rates (cases/total population), often misinterpreting them as infection risks (infections/total population) or disease risks (cases/infected population). We examined these three measures in a pediatric cohort (N≈3,000) over two...
• Social Stressors, Arboviral Infection, and Immune Dysregulation in the Coastal Lowland Region of Ecuador: A Mixed Methods Approach in Ecological Perspective Mon, 02 Aug 2021 06:00:00 -0400
  Aedes aegypti, the mosquito that transmits arboviral diseases such as dengue (DENV), chikungunya (CHIKV), and Zika viruses (ZIKV), is present in tropical and subtropical regions of the world. Individuals at risk of mosquito-borne disease (MBD) in the urban tropics face daily challenges linked to their socio-environment conditions, such as poor infrastructure, poverty, crowding, and limited access to adequate healthcare. These daily demands induce chronic stress events and dysregulated immune...
• Chikungunya Fever in Southern Thailand, 2018 Mon, 02 Aug 2021 06:00:00 -0400
  Infection by the mosquito-borne chikungunya virus (CHIKV) causes acute febrile illness and debilitating arthralgia. Outbreaks are sometimes not recognized because of its clinical resemblance to the more common dengue fever ubiquitous in tropical countries. An upsurge of dengue-like illness was reported in Satun province located in southern Thailand during the rainy season in 2018. We investigated probable outbreak of CHIKV disease. We collected serum samples from 127 patients and tested for...
• Clinical Features of Acute Chikungunya Virus Infection in Children and Adults during an Outbreak in the Maldives Mon, 02 Aug 2021 06:00:00 -0400
  The chikungunya virus is an arthritogenic arbovirus that has re-emerged in many tropical and subtropical regions, causing explosive outbreaks. This re-emergence is due to a genomic polymorphism that has increased the vector susceptibility of the virus. The majority of those infected with chikungunya virus exhibit symptoms of fever, rash, and debilitating polyarthralgia or arthritis. Symptoms can persist for weeks, and patients can relapse months later. Fatalities are rare, but individuals of...

  Newly emerging or re-emerging infections are posing continuous threat to both public health system and clinical care globally. The emergence of infections especially caused by arboviruses can be linked to several mechanisms which include geographical expansion linked to human development and transportation, global warming, enhanced transmission in peridomestic area and close proximity of human habitations to domestic as well as wild animals. The co-circulation of Dengue, Chikungunya and Zika is...

• Correlative imaging using super-resolution fluorescence microscopy and soft X-ray tomography at cryogenic temperatures provides a new way to assess virosome solutions for vaccine development Sun, 01 Aug 2021 06:00:00 -0400
  Active Virosomes (AVs) are derivatives of viruses, broadly similar to 'parent' pathogens, with an outer envelope that contains a bespoke genome coding for 4-5 viral proteins capable of eliciting an antigenic response. AVs are essentially novel vaccine formulations that present on their surface selected viral proteins as antigens. Once administered, they elicit an initial "anti-viral" immune response. AVs are also internalised by host cells where their cargo viral genes are used to express viral...
• Computational identification of repurposed drugs against viruses causing epidemics and pandemics via drug-target network analysis Sat, 31 Jul 2021 06:00:00 -0400
  Viral epidemics and pandemics are considered public health emergencies. However, traditional and novel antiviral discovery approaches are unable to mitigate them in a timely manner. Notably, drug repurposing emerged as an alternative strategy to provide antiviral solutions in a timely and cost-effective manner. In the literature, many FDA-approved drugs have been repurposed to inhibit viruses, while a few among them have also entered clinical trials. Using experimental data, we identified...
• A single dose of ChAdOx1 Chik vaccine induces neutralizing antibodies against four chikungunya virus lineages in a phase 1 clinical trial Sat, 31 Jul 2021 06:00:00 -0400
  Chikungunya virus (CHIKV) is a reemerging mosquito-borne virus that causes swift outbreaks. Major concerns are the persistent and disabling polyarthralgia in infected individuals. Here we present the results from a first-in-human trial of the candidate simian adenovirus vectored vaccine ChAdOx1 Chik, expressing the CHIKV full-length structural polyprotein (Capsid, E3, E2, 6k and E1). 24 adult healthy volunteers aged 18-50 years, were recruited in a dose escalation, open-label, nonrandomized and...
