KARACHI: Number of deaths caused by dengue virus is on rise in Sindh and the number has doubled as compare to previous year, officials informed on Tuesday.According to report issued by Sindh’s Prevention and Control Program for Dengue, so far there have been six deaths in the province. Last year the number of deaths was three.Every year government spends hefty amount on measures to prevent the dengue outbreak but so far authorities have failed to control the disease. However, Prevention and Control Program for Dengue still insists that it is doing its ‘best’ to control the disease.Dr Abdul Rashid Shaikh, Program Manager Prevention and Control Program for Dengue has linked the recent rise of the dengue cases with late diagnosis cases.“These deaths have been reported in city’s private hospitals. Probably the number of cases has risen because of delay in treatment of the patients,” Dr Shaikh told Daily Times.He said since Karachi was a mega populous city so it was difficult to control the vector. “You can also see the rise of dengue casualties with poor sanitation conditions in the city which is not in our domain. Also since Karachi is a big city so there is a widespread storage of water in tanks that also compound the problem,” Dr Shaikh opined.Dengue fever is a mosquito-borne tropical disease caused by the dengue virus. It is caused by four different viruses and spread by Aedes mosquitoes. Dengue virus can cause illness and death in some cases. According to Dr Shaikh, provincial prevention and control program for dengue was doing hard to control the disease. The number of deaths may be double than last year, but performance can be gauged from the fact that number of cases have been reduced.“There were 2,418 cases in year 2016. However, the number of cases this year stood at 999 so far. This is the performance of our program”, he noted. Published in Daily Times, September 13th 2017.
