Malaysia has been grappling with an outbreak of leptospirosis. This bacterial infection, although not new to the region, has resurfaced with alarming vigour, raising concerns among health authorities and the general public alike.
The Incident
After undergoing water therapy at the Jasin Hot Springs, 33 people exhibited symptoms of Leptospirosis like fever, cough, cold, and muscle aches. The 33 people were 15 students, nine teachers, and three guardians from a school in the Melaka Tengah district, as well as six members of the public. Melaka Health Director Dr Ruzita Mustaffa said that the patients were in stable condition. Some patients were admitted to Melaka Hospital for further treatment, while others received outpatient treatment at Ayer Keroh Health Clinic. On 13 June 2024, the second sample of five patients were taken to test for the disease.
A risk assessment conducted at the hot springs found that the area is conducive to the spread of Leptospirosis. Rat urine infected in the water is suspected to be the cause. That contamination facilitated the transmission of Leptospira bacteria. Authorities have instructed the hot springs operators to carry out cleaning work, change the pool water regularly according to a schedule, maintain cleanliness, and ensure there is no infestation of rats or other disease-carrying animals.
What is Leptospirosis?
Bacteria of the genus Leptospira cause leptospirosis, a zoonotic disease. It primarily affects humans and animals, including rodents, livestock, and pets. The bacteria thrive in warm, moist environments such as tropical regions, making countries like Malaysia particularly susceptible to outbreaks.
How does Leptospirosis Spread?
Leptospirosis outbreaks typically stem from environmental factors facilitating the transmission of Leptospira bacteria, primarily through water contaminated with the urine of infected animals, notably rats. Heavy rainfall or flooding can exacerbate the spread, as contaminated water sources proliferate. Urbanisation exacerbates the risk as certain occupations and activities, such as outdoor recreation, increase exposure. Poor hygiene and behaviours like walking barefoot in contaminated areas further heighten susceptibility.
What are the Symptoms of Leptospirosis?
Leptospirosis manifests with a range of symptoms, from fever and muscle aches to jaundice and kidney involvement. Patients may experience a sudden onset of high fever, accompanied by muscle pain, headaches, chills, and red eyes. Gastrointestinal symptoms like nausea and vomiting can also occur, along with abdominal pain and, in some cases, a mild rash. Severe cases may involve kidney damage, leading to decreased urine output and swelling in the extremities.
Prompt medical attention is essential, especially after potential exposure to contaminated water or soil, to facilitate early diagnosis and appropriate treatment. This will minimise the risk of complications and promote a faster recovery.
Antibiotics such as doxycycline and penicillin are commonly used to combat the infection. In severe cases, hospitalisation and supportive care may be necessary to address complications such as organ failure.
Conclusion
The leptospirosis outbreak in Malaysia serves as a stark reminder of the persistent threat posed by infectious diseases, particularly in vulnerable communities. Timely intervention, coupled with proactive measures to enhance public health infrastructure and awareness, is essential in mitigating the impact of such outbreaks.
