Study Notes
Vectors and Their Characteristics
- Vectors are organisms that transmit pathogens and parasites to humans or other animals.
- They play a critical role in the lifecycle of many infectious agents, facilitating disease spread.
Examples of Vector-Borne Diseases
- Common vector-borne diseases include malaria, dengue fever, Zika virus, Chikungunya, leishmaniasis, and lymphatic filariasis.
- These diseases are caused by pathogens carried by insects, primarily mosquitoes and ticks.
Burden of Vector-Borne Diseases
- The highest burden of vector-borne diseases is observed in tropical and subtropical regions.
- These areas often experience favorable conditions for the reproduction of vectors and the lifecycle of pathogens.
Infectious Capabilities of Vectors
- Once vectors become infectious, they can transmit diseases through bites, saliva, or excretions.
- This allows pathogens to enter the host’s bloodstream, leading to infection.
Impact of Specific Diseases
- Chikungunya can cause severe joint pain and incapacitation, impacting quality of life.
- Leishmaniasis affects skin and sometimes internal organs, leading to disfigurement and significant health issues.
- Lymphatic filariasis can cause extreme swelling and disfigurement, leading to social stigmas and economic burden.
