  The dengue viruses are parts of the genus  Flavivirus  in the family  Flaviviridae . Onwards with the dengue virus, this genus also contains a number of other viruses transmitted by mosquitoes and ticks that are responsible for human diseases.  Flavivirus  includes  the yellow fever, West Nile, Japanese encephalitis, and tick-borne encephalitis viruses. The dengue virus is a tiny structure that can only replicate inside a host organism. The four almost related dengue viruses — DEN-1, DEN-2, DEN-3, and DEN-4 — are found in the same regions of the world. The dengue virus is an approximately spherical structure composed of the viral genome and capsid proteins surrounded by an envelope and a shell of proteins. Subsequently infecting a host cell, the dengue virus hijacks the host cell's machinery to replicate the viral RNA genome and viral proteins. After maturing, the newly  amalgamated dengue viruses are released and go on to infect other host cells. Dengue fever was first mention a

Chikungunya virus is a member of the genus Alphavirus and the family Togaviridae.  Chikungunya is an arboviral disease carried by Aedes mosquitoes. The virus was first isolated in 1953 in Tanzania.   Chikungunya virus has been identified in over 60 countries across the world. Known human infections in Africa have been at relatively low levels for many years, except for one short period. From 1999 through 2000 there was a large virus outbreak in the Democratic Republic of the Congo. Since then, there have been outbreaks with abnormal time breaks in-between them. While most people associate mosquito bite-related diseases with African countries, the chikungunya virus has touched base in many countries globally. Since 2005, India, Indonesia, Maldives, Myanmar and Thailand have reported over 1.9 million cases. In 2007 there was the transmission of the virus was reported for the first time in Europe, in a localized outbreak in north-eastern Italy. Recently, cases have linked chikungunya to t

 

 Dengue and chikungunya epidemics have major challenging problems and have become essentially of public health importance in India for the recent years, and it has been transmitted by the Aedes genus (Aedes aegypti or Ae. Albopictus) vector mosquitoes [1,2,8,13] . Chikungunya epidemic was reported in 213 districts especially in South India during 2006 with lakhs of suspected fever cases reported, 15,504 cases were screened for blood samples and 1985 cases were clinically confirmed chikungunya [1], and the occurrences of epidemics were continued across the country, since 2006, and it happened in India, after 25 years period of breaks. The dengue epidemics were reported from 24 states / union territories of India with 37070 cases and 227 deaths during 2012 and it steadily increased to become very serious threat to the public [11] . Both dengue and chikungunya are transmitted by the Aedes genus (Aedes aegypti or Ae. Albopictus) mosquito vectors [1,3,7,13] . The environmental det

 

 NASHIK: The rural parts of Nashik district have seen a continuous rise in dengue and chikungunya cases over the past few weeks, prompting the health department to take up various vector control measures. Health officials said there were 125 cases of chikungunya in the rural parts of the district by July-end , which increased by another 29 by August 10. Similarly, cases of dengue which stood at 65 by July-end increased by 19 by August 10. Chikungunya and dengue are both transmitted by the bite of the Aedes aegypti mosquito, which breeds in fresh accumulated water. Senior officials of the district malaria office said that various measures were being taken to control the spread of the two diseases. District Malaria officer Madhav Ahire said that June and July both saw a sharp rise in dengue and chikungunya in the district. Dengue cases were more in Nashik taluka, followed by Sinnar, Dindori and Peth. Meanwhile, chikungunya cases were also more in Peth taluka followed Nashik, Sinnar and T
