Sorry, not to be snarky, here is the "Background" part of the wiki article : "The minister of climate change of Pakistan, Sherry Rehman, said that the provinces of Sindh and Balochistan had received more rainfall than the August average, with 784% and 500% more, respectively.[9][10] Higher than average monsoon rains were also recorded in India and Bangladesh.[11] The Indian Ocean is one of the fastest warming oceans in the world, warming by an average of 1 °C (1.8 °F) (while worldwide temperatures are now at 1.2 °C (2.2 °F) above pre-industrial temperatures, oceans in general are at around 0.7 °C (1.3 °F)).[11] The rise in sea surface temperatures is believed to increase monsoon rainfall.[12][11] In addition, southern Pakistan experienced back-to-back heat waves in May and June, which were record-setting and themselves made more likely by climate change.[13][14] These created a strong thermal low that brought heavier rains than usual.[12][13] The heatwaves also triggered glacial flooding in Gilgit-Baltistan.[14] Pakistan contributes less than 1% of global greenhouse gas emissions, but is one of the places most vulnerable to climate change.[15][16] A study by an international team of climate scientists says that global heating made the flooding up to 50% worse and future floods more likely.[17] However, some of the contributors to the severity of the flooding are local to the country. Deforestation in Pakistan has also been a factor worsening the floods" So much larger than usual rainfall is the problem - they had record flooding - meaning bigger than ever recorded, right? I don't understand why you are talking about public health like that had an impact in the amount of water that was covering more land than ever?
