Whilst the focus has largely been on property damage and evacuations, health experts urge the general public to remain cautious of disease outbreaks that can arise from prolonged exposure to floodwaters. Kalafhi Medical Centre owner, Dr Matlhogonolo Mongwa-Mouwane, has noted that floodwaters often mix with sewage, garbage, and animal waste, creating an ideal environment for bacteria, viruses, and parasites to thrive. “This significantly increases the risk of diseases such as dysentery, hepatitis A, and typhoid fever. Additionally, stagnant water left behind by floods provides a perfect breeding ground for mosquitoes, which can spread malaria, especially in low-lying areas where water accumulates,” she said. The doctor named bilharzia as another serious concern as it spreads when people come into contact with water-containing parasitic worms.
She said children who play or wade in contaminated ponds and puddles are particularly vulnerable. The destruction of toilets, septic tanks, and drainage systems further exacerbates the problem as human waste can easily mix with floodwaters, increasing the likelihood of diarrhoea disease outbreaks in densely populated areas. “Floodwaters can mix with sewage, garbage, and animal waste, creating a breeding ground for bacteria, viruses, and parasites. This contamination increases the risk of illnesses such as dysentery, hepatitis A, and typhoid fever.
