Study Notes
Vector-Borne Diseases
- Fly-borne diseases: Sand fly fever, Leishmaniasis
- Flea-borne diseases: Plague
- Tick-borne diseases: Lyme Disease, Relapsing fever, Typhus
Epidemiology of Vector-Borne Diseases
- Malaria: imported case, introduced case, indigenous case
- Annual reported malaria cases and deaths in Malaysia (2000-2018)
- Malaria cases by Plasmodium species in Sabah and Sarawak (2013-2017)
- Malaria cases by Plasmodium species in Peninsular Malaysia (2013-2017)
Malaria
- Distribution of Plasmodium knowlesi malaria cases by state in Malaysia (2018)
- Knowlesi malaria cases in Southeast Asia
- Anopheles mosquitoes as vectors
- Macaca fascicularis, Macaca nemestrina, and Presbytis melalophos as hosts
- Emergence of other zoonotic simian malaria infections in Malaysia and neighboring countries
Malaria Control Measures
- Case investigations/case follow-up to identify sources of infection
- Vector Control: micro-stratification of areas, insecticide spraying, insecticide-treated bednets, anti-larval operations
- Regular spraying of insecticides (e.g., DDT, malathion, Resigen) in endemic areas
- Entomological investigations: geographical distribution of vectors, vectors density, and behavior
- Community participation: health education, lectures, exhibitions, pamphlets, posters, and video
Leptospirosis
- General background: most common zoonotic disease worldwide, caused by Leptospira bacteria
- Epidemiology: rodents, dogs, livestock, wild animals, and cats as reservoirs
- Human leptospirosis results from direct or indirect contact with contaminated urine, water, or soil
- Not contagious between humans
Leptospirosis Control Measures
- Avoid contact with contaminated water or soil
- Avoid touching objects contaminated with animal urine
- Wear protective clothing and cover cuts and wounds
- Make water safe to drink by boiling or using chemical treatment
Japanese Encephalitis
- General background: virus spread through infected mosquito bites
- Found in pigs and birds, passed to mosquitoes when they bite infected animals
- Not contagious between humans
- Most people experience mild or no symptoms
Japanese Encephalitis Control Measures
- Cover breeding places (e.g., puddles of water) with sand
- Keep pigsties clean
- Isolate pig farms from villages and make them mosquito-proof
- Vaccination: live, attenuated virus vaccine (primary immunization and booster dose)
- Use repellent (e.g., DEET)
Filariasis
- General background: lymphatic filariasis (LF) is a major cause of permanent disability
- Epidemiology: endemic in 8 states in Malaysia; 120 million people infected worldwide
- Control measures: mass drug administration (MDA) program and National Lymphatic Filariasis Elimination Program
