TAG: GS 3: SCIENCE AND TECHNOLOGY
THE CONTEXT: There has been an emergence of a severe health threat that poses a greater risk to the state’s population: a deadly outbreak of Leptospirosis.
EXPLANATION:
Leptospirosis
- Leptospirosis, commonly referred to as “rat fever,” is a bacterial infection caused by the Leptospira bacteria found in the urine of infected animals, particularly rats.
- The disease primarily spreads through exposure to water or soil contaminated by infected animal urine.
- The bacteria can enter the human body through skin breaks or mucous membranes, making people in flood-prone and waterlogged areas especially vulnerable.
- It is most common in tropical and subtropical areas with high rainfall.
- This year, Kerala has seen a significant increase in Leptospirosis cases, with nearly all districts reporting infections.
- The state health department has confirmed 121 deaths so far, with an additional 102 cases suspected.
- In August alone, 24 people succumbed to the infection.
- Currently, 1,170 individuals are undergoing treatment for Leptospirosis in hospitals across Kerala, a number that continues to rise rapidly.
Impact of Monsoon and Poor Waste Management
- The surge in Leptospirosis cases has been attributed to heavy monsoon rains that have resulted in waterlogging and flooding, conditions ideal for the spread of the bacteria.
- An alarming increase in cases and fatalities has been noted since 2022, emphasizing that preventive measures like wearing protective gear and maintaining personal hygiene are crucial in reducing the risk of infection.
- The role of inadequate waste management in the proliferation of the rat population, further exacerbating the spread of Leptospirosis.
- He stressed the urgent need for better waste management practices to control the rodent population and reduce the risk of bacterial transmission.
Public Health Measures
- In response to the outbreak, the Kerala state government has made preventive medication, such as doxycycline, available at health centers across the state.
- Health officials urge the public, especially those at high risk due to occupational exposure to contaminated water, to exercise caution and seek medical advice for preventive measures.
Symptoms and Complications of Leptospirosis
- Leptospirosis presents with symptoms such as fever, muscle pain, and headaches.
- More severe symptoms may include rapid breathing, low blood pressure, and jaundice.
- The infection can lead to serious complications if not treated promptly, including renal impairment, meningitis, liver failure, and respiratory distress.
- Health experts emphasize the importance of early detection and treatment to prevent fatalities and call for further research into the spread of the disease.
Broader Health Challenges in Kerala
- Alongside the Leptospirosis outbreak, Kerala continues to battle other water-borne and vector-borne diseases exacerbated by the monsoon season.
- Hepatitis A outbreaks have been reported in several districts, with Malappuram, Kozhikode, and Ernakulam among the hardest hit.
- As of August 21, 2024, there have been 4,306 confirmed cases and 41 deaths from Hepatitis A.
- Additionally, the state has reported 13,948 confirmed and 37,735 probable dengue cases, with 54 confirmed and 40 probable dengue-related deaths.
Criticism of Public Health Infrastructure
- These recurring outbreaks have highlighted significant gaps in Kerala’s public health infrastructure, particularly in ensuring the provision of safe drinking water.
- The Kerala Water Authority and local self-governments have faced criticism for failing to adequately address water quality issues, which are central to the spread of these diseases.
- There is a pressing need for improved public health strategies, including enhanced pre-monsoon cleaning efforts and wider distribution of preventive medications to those most at risk.
