Pakistan is again calling for international aid amid rising concerns over possible infectious disease outbreaks in the wake of widespread flooding.

Since mid-June, various regions of Pakistan have seen rainfalls significantly heavier than the annual average.

Local disaster authorities say 1,191 people have been confirmed dead so far.

The flooding has severed roads and railways. Food and medicine remain in short supply.

Climate Change Minister Sherry Rehman on Wednesday warned of possible outbreaks of infectious diseases such as malaria and cholera due to worsening sanitary conditions.

The minister told reporters that mosquitoes have been found in the affected areas, and expressed concern about waterborne diseases. She added that many people could become ill.

Rehman called the latest flooding in her country a climate disaster. She said Pakistan is affected by global warming even though it bears little responsibility for it.

She said countries emitting large amounts of carbon dioxide should be held responsible.
