Health in Malaysia
Leptospirosis is a water contract disease caused by bacteria of the genus Leptospirabacterial. It is a disease that affects both humans and animals. The number of leptospirosis cases had steadily increased from 2011 (2,268 cases with 55 death) to 2015 (8,291 cases with 78 death) and 5,284 cases with 52 death in 2016. Leptospirosis can have important health impact and is a burden to the nation if not well controlled. Addressing leptospisoris includes maintain a clean environment and by not swimming or wading in water that might be contaminated with animal urine, or eliminating contact with potentially infected animals.
Leptospirosis
The number of cases increase during the rainy season in the tropics and during the late summer or early fall in Western countries. This happens because leptospires survive best in fresh water, damp alkaline soil, vegetation, and mud with temperatures higher than 22 °C. This also leads to increased risk of exposure to populations during flood conditions, and leptospire concentrations to peak in isolated pools during drought. There is no evidence of leptospirosis having any effect on sexual and age-related differences. However, a major risk factor for development of the disease is occupational exposure, a disproportionate number of working-aged males are affected. There have been reported outbreaks where more than 40% of people are younger than 15. “Active surveillance measures have detected leptospire antibodies in as many as 30% of children in some urban American populations.” Potential reasons for such cases include children playing with suspected vectors such as dogs or indiscriminate contact with water.
