Sir: Dengue fever seems to have launched a full-fledged attack on the people of Lahore. Cases of dengue fever are being reported from different localities quite regularly without any let-up. Punjab Chief Minister Shahbaz Sharif has been reviewing dengue fever situation every now and then and issuing directions to health officials concerned to remain vigilant, and inform the people to take preventive measures. But quite regretfully health officials down the line and field staff somehow are not translating the directions of the Chief Minister into action in letter and spirit. Spray against dengue fever does not seem to be undertaking in most localities as a result of which more and more dengue fever cases are being reported in different hospitals also every day. The Chief Minister should pull up health officials concerned and should review reports about dengue fever on day to day basis, and those not performing their duties efficiently and properly in this regard should be given a stern warning. The Chief Minister who is known to be hard task master is quite obviously very much concerned about the healthcare of the people at large and hopefully will not spare lethargic health officials either. The people themselves should also be taking preventive measures not allowing stagnation of water, garbage, etc. inside and outside their houses. Print and electronic media should also motivate the people in prevention and fight against dengue fever. Please remember, healthy people make healthy nation, and a healthy nation keeps working hard for progress, development and prosperity. MOHAMMAD ZAHID Lahore
