Karachi (PPI) - The persisting heat weave in Karachi is causing problems for everybody, but the children are particularly hit hard by it, rising the cases of diarrhoea, vomiting and sunstroke by almost 50 percent in the City hospitals. The heat weave would continue for three to four more days, predicts Met Office, while doctors have warned parents to save their children from undue exposure in the sun, while giving them plenty of clean water and fluids. The prevailing heat weave has badly affected the children, and both government and private hospitals are receiving more children in their OPDs and emergencies. The National Institute of Child Health (NICH) sources say there is 40 to 50 percent rise in children cases, while almost the same situation is being witnessed at the OPD and emergency of the Civil Hospital Karachi (CHK), with the rise of mercury. National Institute of Child Health (NICH) Director Professor Abdul Ghaffar Nagi said that his hospital, the biggest state-run facility for children in Karachi, has seen almost 50% increase in the number of patients during the current hot spell. He added that 30 to 35 seriously ill children are being admitted to the hospital, daily. He said the children suffering from diarrhoea, and other waterborne diseases are mainly coming from poor congested slums and Katchi Abadies of Karachi. Prof Nagi said that the number of diarrhoea and hepatitis patients always increase in the summer. He added that children suffering from loose motions and vomiting are coming to the hospitals from almost every part of the city. Head of the Paediatric Ward-II at the Civil Hospital Karachi (CHK) Prof. Iqbal Memon, talking to PPI on Monday, said that the number of children being received at the CHK emergency, daily, has risen by almost 50 percent due to the prevailing heat wave. He said majority of cases are heat-related waterborne diseases like diarrhoea, hepatitis A and E, typhoid and gastro. He said these are common diseases amongst children in this hot season. He said that stomach, intestinal and liver diseases always get on rise in the summer season. He added that heat-stroke is another disease affecting children in Karachi at large. The parents should keep their children indoors at noon, he suggested. Children and elders should cover their heads if they have to go out of their homes in the scorching sun, he added. The people should use clean and boiled water and other fluids to save them from dehydration, he said. Parents should take care that their children are not using contaminated water and substandard ice-lollies. The people should consume Lassi, cucumbers, water melons and melons to beat dehydration, he added. He added that people must take adequate amount of hygienic food and water. He said stale food and rotten fruits and vegetables be avoided at all costs. The global warming has certainly behind the intensity of summer in the month of April, says Dr. Yasmeen Qazi, an Assistant Professor at the NICH. She said unhygienic conditions in the city are behind various diseases. She said in hot weather gutter pipes often burst and sewerage water is mixed with drinking water, causing diarrhoea and gastro, especially amongst kids. The present rise in the number of patients is directly correlated with the persisting heat wave, she observed. The people must use boiled water and not to consume eatables being sold by vendors in the streets, she advised. Dr Qaiser Sajjad, former secretary general of Pakistan Medical Association (PMA) Karachi said Karachi is sizzling under 41 degree centigrade and waterborne diseases, especially amongst youngsters are on the rise. He said that every year almost 3million people suffer from waterborne diseases in Pakistan and some 1.2million die from them. He said use of boiled water and other clean fluids is a must in the hot weather. A full grown up person should use 15 to 18 glasses of boiled water during the 24 hours in hot weather, he suggested. He added typhoid, hepatitis A and E, cholera and gastro affect children most in this blistering season. People could use chlorine tablets, being sold in the market, to clean water, he said. He added that people, who use boiled water, must avoid from cooling it with the ice purchased from market, as it is usually made from the contaminated water. He said that people must thoroughly wash vegetables and fruits with clean water before consuming them. He added that school going children must not use unhygienic beverages, ice creams and lollies being sold by vendors and ice-lolly men outsides schools. Dr Sajjad, who is also a renowned ENT surgeon of Karachi, said people are also suffering from ear, nose and throat problems, due to the use of chilling water in this extreme hot season, he said. He said that the Karachi Water and Sewerage Board (KWSB) is not supplying clean water in any part of the city. He added that it is governments responsibility to provide safe and clean water to every citizen. Chief Metrologist, Met Office, Muhammad Riaz, when contacted, said the persisting heat wave will continue for three to four more days in Karachi and the maximum temperature would fluctuate between 39 to 43 degree centigrade. The present hot spell in Karachi is due to absence of rain and sea breeze, that is why even the coastal areas are experiencing high temperature in the month of April, he said. He noted that weather pattern of Karachi is changing, as the city which normally experience summer in the month of May is braving this hot spell in the month of April.
