Phatthalung Health Officer warns people in Muang and Cwnknun districts,
areas that are still affected by flooding, of the risk of leptospirosis.
People are advised to wear boots when walking through flooded areas for
a long time to prevent contact with bacteria from water and to clean
their feet immediately after that. If there are wounds, people should
immediately seek medical attention and not let them become chronic
wounds. 30 villagers in flooded areas of Muang and Cwnknun districts
were infected with leptospirosis in the past months.
The flooding in many areas is back to normal 3 days after the rainfall
stopped. There is no water flow in the roads of every village and
traffic is normal. But there are some areas in Muang and Cwnknun
districts that are still flooded, with an average flood height of 20-30
centimeters. More than 800 families are affected by the floods. It is
expected that the situation will be back to normal if there is no more
rain this week.
