BHUBANESWAR: The National Centre for Disease Control (NCDC) team, which visited dengue epicentre Angul district, has found that it was the mineral transportation process which has triggered the spread of the killer fever.By Sunday, dengue has claimed 12 lives and most of them reported from Angul. All the five deaths on the day were from Angul which is the coal heartland of the State.The NCDC team, led by Joint Director CS Agarwal, found that the numerous truck workshops are responsible for dengue spreading its tentacles in the area in such a menacing manner. Sources said that the team had called for intensified drive to address the situation on a war-footing since ‘clustering’ of infection has been noticed.It is the trend of ‘clustering’ of infection which has led to indigenisation of the dengue infection in the region. The team found that there are several families which have been infected because one member carried the virus and since the condition is now conducive for transmission of the virus, others contracted it.The Angul-Talcher region witnesses movement of hundreds of coal-bearing trucks which need halting for washing as well as repair. Such practices have led to stagnant water pools across the region. Besides, piling up of tyres, which hold stagnant water, is another major cause of the fast spread.“Since the vector population is abundant, the spread has been facilitated by the prevailing condition and indigenisation of the infection,” said an expert.The team was also informed of at least half a dozen haemorrhagic dengue cases.Currently, Orissa has seen emergence of the serotype 2 of the dengue virus. Last year, a test by Regional Medical Research Centre had found the serotype in Malkangiri district where an outbreak was reported. In southern India, serotype 3 and 4 have been detected.Health experts said the State Government must act swiftly before multiplicity of infection takes place in Angul and other places of the State where dengue has been reported.If the second wave of outbreak takes place, it may cause more harm because people keep travelling and are prone to multiplicity of infection.
