Anthrax, a serious infectious disease transmitted from animals to humans, has recently surged in the southern provinces of Laos, with officials reporting a significant number of cases.
The Director of the Department of Communicable Disease Control, Dr. Rattanaxay Phetsouvanh, disclosed during a media briefing on April 9, 2024, that the disease has infected 129 people and resulted in one fatality so far this year. Among these, 94 cases were reported in Champasak province, including 52 in Champasak district, 13 in Sanasomboun, and 2 in Sukhuma. Additionally, 27 cases were recorded in Saravan province, with 16 in Lakhonepheng district and 11 in Khongsedone.
Anthrax outbreaks are not new to Laos. In 2009, outbreaks occurred in Saravan district, followed by subsequent cases in 2010, 2011, 2022, and 2023 in various southern regions. Despite these recurring outbreaks, preventive measures and rapid treatment have helped mitigate the risks.
Anthrax, caused by the spore-forming bacterium Bacillus anthracis, occurs naturally in soil and can remain dormant for years until disturbed by environmental changes such as flooding or heavy rain. Grazing animals like cattle and buffalo often ingest the spores, leading to infections that may transmit to humans through contact or consumption.
Symptoms in humans include fever, severe abdominal pain, difficulty breathing, and blisters resembling burns. However, timely antibiotic treatment significantly reduces mortality risks.
Health officials emphasize the importance of prompt detection and control measures to prevent the spread. Recommendations include safe handling of animals, vaccination of livestock, and proper disposal of dead animals through burial or incineration.
The One Health approach, which integrates human, animal, and environmental health, remains critical in addressing this issue. Efforts to combat anthrax require collaboration across sectors, involving health professionals, veterinarians, journalists, and the community. Such partnerships are essential in safeguarding public health and preventing future outbreaks in Laos and the region.
