French-Austrian drugmaker Valneva's vaccine candidate against chikungunya, a mosquito-borne virus that causes occasional outbreaks across the world, showed promising results in a large new trial, a study said on Tuesday. (thedailystar.net)

Samples from Tapachula were collected from patients who sought treatment at the Centro Regional de Investigacion en Salud Publica, whereas in La Libertad and Ciudad Hidalgo, researchers surveyed houses to identify potential case-patients. (cdc.gov)
But earlier this year, she says, "We receive every day patients with chikungunya, including some with no travel history. (michiganradio.org)
In this scenario of reemergence of outbreaks, there is a concern about the intensity of the disease in the acute phase, which may cause incapacity, and the risk of complications in users of immunosuppressive drugs, especially patients with rheumatological disease who already have joint involvement [ 8 , 9 ]. (hindawi.com)
There are also indications that patients may be able to spread the virus while pre-symptomatic or asymptomatic. (snohd.org)
We also determined the neutralizing antibody titer in response to the viral load in patients, and our data support the evidence that an effective neutralizing antibody response against the virus is important for control of the viral load. (tropmedres.ac)

The virus has circulated in forested regions of sub-Saharan African in cycles involving nonhuman primate hosts and arboreal mosquito vectors. (wikipedia.org)

But a large-scale outbreak in the mainland U.S. will not be easy to achieve. (cdc.gov)

Despite the benefit of the use of bDMARDs, these drugs are known to have immunomodulatory and immunosuppressive effects, predisposing the users to an increased risk of infections and their complications by viruses such as cytomegalovirus (CMV), varicella zoster virus, Epstein-Barr virus, hepatitis B virus, and influenza virus [ 8 - 10 ].

Getting accurate chikungunya surveillance data is challenging because the disease is not a "nationally notifiable disease" in the United States. (cdc.gov)
Fur- thermore, trainees investigated over 100 outbreaks, analysed and evaluated 95 surveillance systems, conducted 30 planned studies and presented 70 oral and poster presentations at national and international conferences. (who.int)
Completion of this project will have a major impact in the control of alphaviruses by spurring novel surveillance strategies and countermeasures targeting virus-host interactions. (hhs.gov)

Research at the CVR focuses on the interaction between the virus and it mosquito-vector, specifically the innate immune response and how this influences vector competence and transmission. (gla.ac.uk)
As age is a risk factor for severity and mortality of chikungunya disease, the strong immune response observed in older participants might be particularly beneficial. (genengnews.com)
Instead, the study tested for an immune response at levels that are thought to protect against the disease if infected with the virus. (genengnews.com)
