Malaria Control Program

• Vision: Reduce malaria burden and aim for elimination.
• Goal: Achieve an Annual Parasite Index (API) of <1 per 1000 population by 2017.
• Strategies:
• Screening all fever cases for malaria.
• Treating all positive cases promptly and effectively.

Preventive Measures

1. Against Larvae:

• Use larvicides in stagnant water (e.g., Temphos, Paris green).

1. Against Adult Mosquitoes:

• Spray residual insecticides like DDT.
• Use mosquito nets and repellents.

1. Community Protection:

• Promote protective clothing and use of mosquito mesh.
• Educate the community about prevention and management.

Health Education

• Essential for informing the community about the causes, spread, and prevention of vector-borne diseases.
• Use various educational approaches for effective communication.

This summary provides a clear overview of the key points related to National Vector-Borne Diseases and their control.

National Malaria Control Program Under NVBDCP.

• Main Goal: Control and prevent malaria through effective strategies and treatment.
• Diagnosis & Treatment:
• Check for malaria with blood smears (thin and thick).
• Start treatment while waiting for lab results (presumptive treatment).
• Follow the treatment plan based on the type of malaria detected.
• Ensure the first dose is given under observation.
• Role of Community Health Nurse:
• Monitor vital signs of all patients.
• Never ignore any case of fever.
• Educate patients and their families about malaria.
• Advise patients to drink plenty of water and monitor for vomiting after taking medicine.
• If the patient shows signs of severe illness (e.g., drowsiness), refer them to the hospital immediately.
• Follow-up: Regularly check on the patient and their family to ensure recovery and prevent further spread of malaria.

Lymphatic Filariasis Elimination Program: Simple Notes

• Disease Overview:
• Lymphatic filariasis, also known as elephantiasis, is a tropical disease affecting over 120 million people worldwide.
• It causes severe disfigurement and disability in about 40 million people.
• Program History:
• The National Filarial Control Program (NFCP) began in 1955.
• In 2003, it was included in the National Vector Borne Disease Control Program (NVBDCP).
• Training and research are conducted by the National Institute of Communicable Diseases, Delhi.
• Elimination Definition:
• The disease is considered eliminated when less than 1% of the population carries the microfilaria, and new-borns are free from the infection.
• Major Activities:
• Goal: The goal is to eliminate lymphatic filariasis by 2015, as per the National Health Policy 2002.
• Strategies:
  • Annual mass drug administration (MDA) with a single dose of antifilarial drugs like DEC and Albendazole for at least 5 years.
  • Home-based care for lymphedema and hydrocele surgeries.
  • Anti-larval and anti-mosquito measures in endemic areas.
  • Improved sanitation, including drainage facilities and preventing water stagnation.
  • Health education on environmental cleanliness and use of insect repellents.
• Exclusions from MDA:
• Pregnant women, children under 2 years, and seriously ill people are excluded from MDA.
• Ongoing Efforts:
• Microfilarial surveys and drug administration are regularly conducted to monitor progress.
• Public awareness campaigns encourage regular treatment and home care management.

Kala-Azar Control Program:

• Program Overview:
• The Kala-azar control program is a centrally sponsored initiative launched in 1990-91.
• Before the use of DDT, Kala-azar was highly endemic in India, causing significant economic harm due to high morbidity and mortality.
• Elimination Strategies:
• Enhanced Case Detection: Improved methods for finding and treating cases.
• Rapid Diagnostic Kits: Introduction of PK39 kits for quick diagnosis.
• Oral Drug “Miltefosine”: Used for treating Kala-azar.
• Vector Control: Fogging with pyrethroid instead of DDT to eliminate sandflies.
• Behavioral Impact Communication: Educating the community to encourage cooperation in eradication efforts.
• Capacity Building: Strengthening the skills of healthcare providers.
• Supervision & Monitoring: Regular checks and evaluations to ensure program effectiveness.
• Case Search for Kala-azar:
• Quarterly Searches: More frequent searches, called “Kala-azar fortnight surveys,” involving door-to-door visits.
• Incentives: ASHA workers receive ₹300 per identified case and ₹100 for community support during insecticide sprays. Patients receive ₹500 during hospitalization.
• Revised Eradication Strategy (2014):
• New Diagnostic Tools: Introduction of RDT developed by ICMR.
• New Treatment: Liposomal Amphotericin B (IV 10 mg-single dose) provided free by WHO.

Japanese Encephalitis (JE) Control Program:

• Disease Overview:
• JE is a severe disease causing up to 20,400 deaths annually worldwide.
• Survivors often suffer from long-term neurological issues such as paralysis or seizures.
• The disease is prevalent in rural and peri-urban areas of several Indian states.
• Vector Control Strategies:
• Alternate Wet and Dry Irrigation (AWDI): Helps control mosquito breeding by disrupting their lifecycle in paddy fields.
• Biological Control: Use of natural predators like Gambusia fish to control mosquito populations.
• Chemical Control: Application of deltamethrin, organophosphates, and carbamates to reduce mosquito numbers.
• Health Education:
• Community Involvement: Educate and engage communities in cleaning surroundings and eliminating mosquito breeding sites.
• Personal Protective Measures: Wearing full-sleeved clothing, using mosquito nets, and applying repellents.
• Management:
• No specific treatment is available; supportive care includes feeding, airway management, and seizure control.
• Long-term care and rehabilitation may be needed for survivors.
• Surveillance:
• Clinical Surveillance: Early diagnosis and management of JE patients at primary health centers.
• Vector Surveillance: Monitoring mosquito behavior in risk areas to adapt control measures accordingly.
