Zika virus is a flavivirus that is primarily transmitted by infected Aedes mosquitoes. This vector also transmits dengue and chikungunya viruses and is commonly found in tropical and sub-tropical environments in Africa, the Americas, Asia and the Pacific. Although Zika virus was first identified in humans in 1952, few outbreaks were documented prior to 2015.(1) Human infection can be asymptomat...

Ten chikungunya virus isolates from human plasma collected in Haiti from May to August 2014, in the midst of a chikungunya fever outbreak, were fully sequenced. The resulting genomic sequences are nearly identical, and phylogenetic analyses indicate they belong to the Asian lineage of the virus.

In 2007, the first chikungunya outbreak ever occurring in a temperate area of the Northern Hemisphere was reported in Emilia-Romagna, Italy. The present study aims to evaluate knowledge, attitudes and practices regarding chikungunya infection. Information was collected by standardised telephone questionnaire, administered to 325 people during a seroprevalence survey performed in the outbreak ar...

Given the recent emergence of chikungunya in the Americas, the accuracy of forecasting and prediction of chikungunya transmission potential in the U.S. requires urgent assessment. The La Reunion-associated sub-lineage of chikungunya (with a valine substitution in the envelope protein) was shown to increase viral fitness in the secondary vector, Ae. albopictus. Subsequently, a majority of experi...

Dengue, a Flavivirus and chikungunya, an Alphavirus, transmitted by Aedes mosquitoes, are a cause of great concern to public health in India. Every year, thousands of individuals are affected and contribute to the burden of health care. Dengue outbreaks have continued since the 1950s but severity of disease has increased in the last two decades. Chikungunya outbreaks started in the 1960s and dw...

Dengue, malaria and chikungunya are important mosquito-borne diseases and endemic in India. Each of these diseases contribute substantially to the morbidity, if not diagnosed and managed at an earliest. The clinical features common to all the three diseases are prolonged fever, backache, joint pain, rash, headache, running nose and epistaxis causing challenge in diagnostic segregation based on ...

Chikungunya is a mosquito-borne disease caused by an alphavirus from the Togaviridae family. The Chikungunya virus (CHIKV) is transmitted by the Aedes mosquitoes, primarily Aedesaegypti and Aedesalbopictus, the Asian ‘Tiger’ mosquito. Chikungunya virus breeds in the skin, moves to the liver, muscle, lymphoid tissue and brain, through the blood. The usual clinical signs of chikungunya are non-sp...

Chikungunya virus is no stranger to the Indian sub­ continent. Since its first isolation in Calcutta, in 1963, there have been several reports of chikungunya virus infection in different parts of India. The last outbreak of chikungunya virus infection occurred in India in 1971. Subsequently, there has been no active or passive surveillance carried out in the country and therefore, it ‘seemed’ t...
