ISLAMABAD: The United Nations has said outbreaks of mosquito-borne and water-borne diseases in flooded Pakistan were a “growing concern,” as deaths from infections, malaria and dengue fever have caused more than 300 deaths since July in the worst-hit province of Sindh, according to health officials.

The death toll from the deluge itself has reached 1,663, including 614 children and 333 women, a figure that does not include deaths from fast-spreading diseases, according to data from the National Disaster Management Authority.

“Outbreaks of vector-borne and water-borne diseases are a growing concern in Sindh and Balochistan provinces, where many districts remain inundated by floodwaters,” Stephane Dujarric, a spokesperson for UN Secretary-General Antonio Guterres, said on Tuesday.

He said floods had damaged nearly 1,500 health facilities across the country, including more than 300 refrigerators and solar power systems, which was disrupting vaccine cold chains.

“Assessments are continuing, but an estimated 7.9 million people remain displaced by the catastrophic floods.  Nearly 600,000 people are living in relief camps, and more than 7,000 schools across Pakistan are being used as temporary relief camps,” the spokesperson said, adding that the UN and its humanitarian partners were continuing to scale up response and had reached more than 1.6 million people impacted by the floods.

“Nearly 600,000 people are living in relief camps, and more than 7,000 schools across Pakistan are being used as temporary relief camps … More than two million houses have been damaged by the heavy rains and floods. More than 25,000 schools and 13,000 km of roads have also reportedly been damaged.”

Record monsoon rains in south and southwest Pakistan and glacial melt in northern areas triggered the flooding that has affected nearly 33 million people in the South Asian nation of 220 million, sweeping away homes, crops, bridges, roads and livestock and causing an estimated $30 billion of damage.

Hundreds of thousands of displaced people are in dire need of food, shelter, clean drinking water, toilets and medicines. Many have been sleeping in the open by the side of elevated highways.

The economic losses from the flooding will slash the country’s GDP growth to around 3 percent from the estimated target of 5 percent set out in the budget when it had narrowly escaped defaulting on its debt in a balance of payment crisis.

Pakistan was already reeling from economic blows when the floods hit, with its foreign reserves falling as low as one month’s worth of imports and its current account deficit widening.
