Understanding Malaria, Dengue, and Chikungunya

What is the primary vector responsible for malaria transmission?

• Female Anopheles mosquitoes

• Aedes mosquitoes

• Male Anopheles mosquitoes

• Culex mosquitoes

How does the Anopheles mosquito contribute to malaria spread?

• The Anopheles mosquito lays eggs in saltwater.

• The Anopheles mosquito is primarily a pollinator of flowers.

• The Anopheles mosquito feeds on plant nectar exclusively.

• The Anopheles mosquito transmits the malaria parasite to humans through its bites.

What are the common symptoms of dengue fever?

• Chronic fatigue and weakness

• Common symptoms of dengue fever include high fever, severe headache, pain behind the eyes, joint and muscle pain, rash, and mild bleeding.

• Nausea and vomiting only

• Skin dryness and itching

Which symptom is most characteristic of severe dengue?

• Sore throat

• Severe abdominal pain

• Mild headache

• Nausea and vomiting

What are the primary prevention methods for chikungunya?

• Use sunscreen to prevent sunburn

• Use insect repellent, wear protective clothing, and eliminate standing water.

• Consume vitamin C supplements regularly

• Increase indoor humidity levels

How can the use of mosquito nets help in preventing malaria?

• They are used to cook food safely.

• They attract more mosquitoes to the area.

• They provide nutrients to the soil.

• The use of mosquito nets helps in preventing malaria by providing a barrier against mosquito bites.

What role does climate change play in the spread of vector-borne diseases?

• Climate change has no impact on vector-borne diseases.

• Climate change facilitates the spread of vector-borne diseases by altering habitats, increasing vector populations, and enhancing pathogen transmission.

• Climate change reduces vector populations and disease spread.

• Climate change only affects land-based diseases, not vectors.

How does temperature affect the breeding of mosquitoes?

• Temperature has no effect on mosquito breeding.

• Higher temperatures decrease mosquito breeding rates.

• Mosquitoes breed only in cold temperatures.

• Temperature affects mosquito breeding by accelerating their life cycle and increasing breeding rates at optimal temperatures.

What are some effective vector control strategies for malaria?

• Chemical fertilizers

• Insecticide-treated bed nets, indoor residual spraying, environmental management, biological control agents.

• Urban development projects

• Pesticide-free farming

How can community awareness contribute to dengue prevention?

• Community awareness has no impact on dengue prevention.

• Community awareness is only effective in urban areas.

• Community awareness contributes to dengue prevention by educating the public, promoting clean environments, and encouraging protective measures.

• Community awareness leads to increased mosquito breeding.
