Dengue continues its grip over Punjab and the provincial capital in particular where 15 people have died from the disease. Three including a boy died from the virus in the city on Wednesday. Chief Minister Punjab Shahbaz Sharif said a case would be lodged against those not providing free treatment for Dengue. Sharif has also directed the administration of private residential colonies to conduct fumigation drives. A case pertaining to the spread of the virus is also being heard at the Lahore High Court (LHC). The court did not receive an answer from district government and health department officials and ordered that they submit their replies by September 16. The court stated that people were dying from Dengue and high ranking officials were not concerned. Opposition members in the Punjab Assembly also staged a walkout with a PML-N MPA claiming that the disease would be controlled within ten days. Over 400 new dengue cases were reported in Lahore and 3,925 people are suffering from the virus. All educational institutions in the city have been closed for 10 days. Eight Chinese engineers have also been infected with the Dengue virus and are receiving treatment at different hospitals of the city. The situation is dire in Faisalabad as well where within a span of 18 hours, 35 new Dengue cases were reported. Overall 220 dengue cases have been reported in the city. The authorities, already under pressure to help hundreds of thousands of flood victims, are struggling to contain dengue fever, officials said on Wednesday. "So far, eight people have died of dengue. We are trying our best to control this epidemic," Jehanzeb Khan, Secretary of the provincial Health Department, told reporters. Health experts say the illness is spreading across the Punjab because of poor hygiene conditions and heavy monsoon rain provides ideal conditions for dengue-carrying mosquitoes to thrive in stagnant waters. The Secretary said the government had launched a fumigation drive to kill mosquitoes.
