Dengue
Dengue is characterized in outbreaks. Outbreak means food borne illness that spreads widely in an area.
Causative agent:-
The causative agent of Dengue Fever (also known as the Devil's Crunch or Breakbone Fever) is the Dengue Fever Virus (DENV), a member of the Flaviviridae family and the Flavivirus species. However, there are fourserotypes of the Dengue fever virus, aptly named DENV-1, DENV-2, DENV-3 and DENV-4 and within these serotypes there are clades and strains that are inherently different in nature. However, as a conclusion, one would say the DENV virus is the agent of Dengue Fever.
Symptoms:-
The list of signs and symptoms mentioned in various sources for Dengue fever includes the 21 symptoms listed below: * High fever - up to 105 degrees Fahrenheit * Severe headache * Retro-orbital pain - pain behind the eye * Severe joint pains * Muscle pains * Muscle aches * Swollen lymph nodes * General weakness * Nausea * Vomiting * Rash * Children get non-typical symptoms * Fever * Weakness * Prostration * Severe headache * Pain behind the eyes * Severe muscle pain * Slowed heart rate * Enlarge lymph nodes * Maculopapular rash
Mode of spread/ transmission:-
Mode of transmission
Dengue is transmitted by the bite of an infected mosquito, particularly Aedes aegypti- female mosquito. . This was first recognized by workers in Queensland early in the 20th century. Aedes aegypti breeds in fresh water and particularly in manmade containers such as old tires, pot plant holders, buckets and tree hollows in urban areas.
Aedes albopictus is a mosquito common in South East Asia and Papua New Guinea and can also be an important vector. Other Aedes species are involved in the enzootic monkey cycle
The principal vector mosquito, Ae aegypti, prefers to feed on humans during the daytime and most frequently is found in or near human habitations. There are two peak periods
