UNITED NATIONS - The World Health Organization (WHO), a Geneva-based UN agency, has said that 20,000 drowning deaths every year in the European region are “entirely preventable”. Most recently, the catastrophic loss of hundreds of lives, including Pakistanis, in the capsizing of a fishing vessel off the Greek coast has brought this into sharp focus, it was pointed out. “In that one single catastrophe, more than 600 people huddled in desperation and drowned together; most bodies will never be recovered,” Dr. Hans Henri P. Kluge, WHO’s regional European director, said in a statement issued in Copenhagen on Monday. “Most of us rarely, if ever, think about drowning as a public health hazard with significant impact,” he said. According to the WHO, the majority of victims tragically drown alone in varied circumstances, from unsupervised pools to deadly rip currents.
