Climate Change-Induced Floods Heighten Risk of Leptospirosis Spread, Australian Study Finds

Kathmandu. Extensive research conducted by an Australian university has indicated that rising storms, excessive rainfall, and floods globally due to climate change are severely impacting human health. According to the study, such natural events create an environment conducive to the spread of the bacterial infectious disease called 'Leptospirosis'. Researchers concluded that the disease, which primarily spreads to humans through contaminated water and soil, sees its risk significantly increase after floods.

As mentioned in the research, the bacteria causing 'Leptospirosis' can survive for long periods in warm environments. Excessive rain and floods increase the likelihood of these bacteria spreading to water sources, fields, settlements, and drinking water supplies. This can lead to a rapid surge in infection among people in flood-affected areas. The risk is particularly higher in areas with poor sanitation.

According to scientists, farmers, livestock keepers, individuals in direct contact with animals, meat processing workers, and those working or bathing in rivers, ponds, and streams are at high risk of this disease. Since an effective vaccine for humans against this disease is not yet available, the study highlighted that public awareness, sanitation, and early testing are extremely necessary for prevention.

The initial symptoms of this disease can resemble common fever, headache, and body aches, posing a risk of delayed identification in many cases. Researchers warned that if not treated promptly, it can cause severe damage to the liver, kidneys, and nervous system, and in severe cases, can even lead to death. Therefore, it has been emphasized that people in affected areas after floods or excessive rainfall should undergo health check-ups, and the government needs to make monitoring and prevention programs in high-risk areas more effective.
