No record of Chikungunya patients in city although many affected
Saira Banu, a domestic help lives in a slum near Shewrapara, had been suffering from high fever and pain in the joints from five days, but could not understand why the fiver showed no sign of let-up even after taking medicine including antibiotic from a pharmacy.
Later she went to a private practitioner and the practitioner surmised that she had been suffering from Chikungunya, which is spreading fast in city.
Chikungunya is a viral disease transmitted to humans by infected Aedes mosquito female Aedes mosquitoes which also carry virus of dengue. It causes mainly fever and severe joint pain including muscle pain, headache, nausea, fatigue and rash.
The Aedes mosquito usually breeds in a small collection of clean water both in and around houses, such as inside a flower vase and intermittent rains poses increase of the breeding, Institute of Epidemiology, Disease Control and Research (IEDCR) Senior Scientific Officer Dr ASM Alamgir told The Daily Observer.
There is no need to wait for testing, it has no specific treatment, Paracetamol is the drug of choice for relieving both fever and pain, Prof Dr Abul Kalam Azad, Director General of Directorate General of Health Services said.
To a query about the number of patients the IEDCR have recorded till Thursday, the authority said, all patient attacked with Chikungunya are not fully recorded in city as the patients take treatment from private practitioners.
But IEDCR advises to remove of all open containers with stagnant water in and outside the houses such as flower pots, unused tyres in open space, tree holes and rock pools and take rest under bed net as there is the risk of transmission to others from the affected persons by mosquitoes.
Dhaka South City Corporation (DSCC) and Dhaka North City Corporation (DNCC) responsible for anti-mosquito drives but Dhaka city residents claim that until March they didn't see the drive which is essential well before the rainy season to disinfect water-logged and labyrinth areas by spraying insecticides.
Both chikungunya and dengue show some common symptoms such as fever, pain, but in Chikungunya the pain is so severe that people find it very difficult to move. It involves pain in all the joints,"
According to World Health Organisation (WHO), both Ae. aegypti and Ae. albopictus have been implicated in large outbreaks of chikungunya. Whereas Ae. aegypti is confined within the tropics and sub-tropics, Ae. albopictus also occurs in temperate and even cold temperate regions. In recent decades, Ae. albopictus has spread from Asia to become established in areas of Africa, Europe and the Americas.
The name Chikungunya first identified in 1953 in Tanzania. India reported an epidemic in 1964. Bangladesh found the first case in 2008 in northern Rajshahi and Chapainawabganj districts. In Dhaka, IEDCR noticed the presence of the disease later in 2O11.
