This was stated by speakers at an awareness seminar on dengue fever arranged by the Department of Continuing Education, University of Agriculture Faisalabad at Iqbal Auditorium.
Dr Maqsood Ahmad from Punjab Medical College, Department of Entomology Chairman Prof Dr Anjum Sohail were key speakers on the occasion. University Community College Principal Prof Dr Khalilur Rehman and Department of Continuing Education Chairman Prof Dr Mahood A Randhawa also spoke on the occasion.
Dr Maqsood Ahmad said that swelling on face, hands and feet, or bleeding from any part of the body, are signs of the infection getting serious and the patient needing urgent treatment and hospitalisation. He said that dengue infection manifested as fever with associated headache, muscle and joint pain, nausea/vomiting and rashes.
Dr Anjum said that ideal temperature for dengue is 15 to 22 centigrade whereas after 35C it starts dying. He said if water is held in a pot for one day, dengue will not lay eggs as it likes stagnant water which is mixed with some dust participles. So after five days, the pot water carries some dust participles, attracting the mosquito because it is the diet of it.
Refuting the idea that dengue bits only at dawn and dusk, he said that dengue likes darkness and it becomes active after finding suitable situation. If dengue is present in room having little light in daytime, it bites.
He urged the people keep home, environment and surrounding clean, remove all stagnant water and containers, keep all drains well maintained and repair all chokes, avoid accumulation of ground water, fill up all defective grounds, not to store water, avoid unnecessary irrigation, cover all containers properly and change flower vase water once a week to prevent dengue mosquito breeding.
Dr Khalilur Rehman said that the university was committed to creating awareness about the issue. He stressed the need for wrapping all unused plastic tyres, using mosquito repellents to avoid mosquito bite.
Prof Randhawa said that the social mobilisation was an effective way to fight the epidemic and students should also take part in the awareness campaign. He said that the first case of dengue was reported in Karachi in 2004. He said that the university was working on various projects on dengue in order to end the disease.
