How Well Do You Know Vector Controls?

1.

Removing areas where vectors of diseases can breed is a method of which of the following?

A.

Treatment
B.

Habitat control
C.

Colour control
D.

Prevention

Correct Answer
B. Habitat control

Explanation
Habitat control is a method that involves removing areas where vectors of diseases can breed. By eliminating or modifying the breeding grounds of disease-carrying vectors, such as mosquitoes or rodents, the spread of diseases can be prevented. This approach focuses on addressing the root cause of the problem by targeting the habitat of the vectors, rather than solely relying on treatment or prevention methods.

What are organisms that transmit diseases pathogens called?

A.

Dangerous
B.

Vectors
C.

Animals
D.

Causatives

Correct Answer
B. Vectors

Explanation
Organisms that transmit diseases pathogens are called vectors. Vectors can be living organisms, such as mosquitoes, ticks, or fleas, that carry and transmit disease-causing pathogens from one host to another. These pathogens can include bacteria, viruses, or parasites. Vectors play a crucial role in the spread of many diseases, including malaria, dengue fever, Lyme disease, and Zika virus. By understanding and controlling vectors, we can effectively prevent and control the transmission of these diseases.

What is the process for developing and strategies for vector control?

A.

Expose Vector Control
B.

Integrated Vector Management
C.

Vector Management
D.

Population Control

Correct Answer
B. Integrated Vector Management

Explanation
Integrated Vector Management (IVM) is the correct answer because it is a comprehensive approach that involves multiple strategies for controlling vector-borne diseases. It includes the coordination of various interventions such as insecticide-treated bed nets, indoor residual spraying, larval source management, and community education. IVM aims to reduce the burden of vector-borne diseases by targeting the entire life cycle of the vector and addressing the environmental, social, and economic factors that contribute to their proliferation. This approach ensures a sustainable and effective control of vectors while minimizing the negative impact on the environment and human health.

Which of these is a method of vector control?

A.

Hand treatment
B.

Killing
C.

Reducing contact
D.

Contact management

Correct Answer
C. Reducing contact

Explanation
Reducing contact is a method of vector control that involves minimizing or eliminating the interaction between humans and disease-carrying vectors. This can be achieved through various measures such as using insecticide-treated bed nets, implementing proper sanitation practices to eliminate breeding grounds, and conducting targeted insecticide spraying in high-risk areas. By reducing contact with vectors, the transmission of diseases can be significantly reduced or prevented altogether.

Which of these can be used in mosquito population control?

A.

Acid
B.

Acid rain
C.

Grenade
D.

Larvicides

Correct Answer
D. Larvicides

Explanation
Larvicides can be used in mosquito population control. Larvicides are substances that are specifically designed to kill mosquito larvae before they can mature into adult mosquitoes. They are typically applied to bodies of water where mosquitoes breed, such as stagnant ponds or ditches. By targeting the larvae, larvicides can effectively reduce the overall mosquito population by preventing the development of new adult mosquitoes. This method of control is often considered more environmentally friendly and targeted compared to other options such as using pesticides or chemicals that may harm other organisms or have unintended consequences.

What is the method of using natural vector predators in vector control called?

A.

Biological control
B.

Chemical control
C.

Handpicking
D.

Dusting

Correct Answer
A. Biological control

Explanation
Biological control is the method of using natural vector predators in vector control. This approach involves the use of living organisms, such as predators, parasites, or pathogens, to control the population of vector species. By introducing these natural enemies into the environment, they can help reduce the population of vectors, such as mosquitoes or ticks, and therefore control the spread of vector-borne diseases. This method is considered environmentally friendly and sustainable, as it relies on natural processes rather than chemicals or manual methods.

In controlling tsetse fly breeding rate, which of these can be done?

A.

Introducing sterile male
B.

Dusting
C.

Breezing
D.

Relocation

Correct Answer
A. Introducing sterile male

Explanation
Introducing sterile male tsetse flies can be done to control their breeding rate. Sterile male tsetse flies are unable to reproduce, so when they are released into the wild, they can mate with female flies but produce no offspring. This reduces the overall breeding rate of tsetse flies, helping to control their population and the spread of diseases they carry.

Which is a subfield of public health?

A.

Bioethics
B.

Community health
C.

Healthcare data collation
D.

Biomedical engineering

Correct Answer
B. Community health

Explanation
Community health is a subfield of public health that focuses on the health and well-being of specific communities or populations. It involves assessing the health needs of a community, developing and implementing health programs and interventions, and evaluating their effectiveness. Community health professionals work closely with individuals, families, and community organizations to promote healthy behaviors, prevent diseases, and improve overall health outcomes. This subfield plays a crucial role in addressing health disparities and promoting health equity within communities.

Which of these is one of the basis of public health?

A.

Economic status
B.

Improved quality of life
C.

Urbanisation
D.

GDP growth

Correct Answer
B. Improved quality of life

Explanation
Improved quality of life is one of the basis of public health because it focuses on enhancing the overall well-being and satisfaction of individuals within a population. By improving access to healthcare, education, clean water, sanitation, and other social determinants of health, quality of life can be enhanced, leading to better health outcomes and overall public health. This approach emphasizes the importance of addressing social and environmental factors that contribute to health disparities and promoting equitable access to resources and opportunities for all individuals.

Which is a common mosquito breeding environment?

A.

Stagnant water
B.

Rooms
C.

The Kitchen
D.

Homes

Correct Answer
A. Stagnant water

Explanation
Stagnant water is a common mosquito breeding environment because mosquitoes lay their eggs in still water. This allows the eggs to hatch and develop into larvae and eventually adult mosquitoes. Stagnant water can be found in various places such as ponds, puddles, and stagnant pools of water. Mosquitoes are attracted to these areas because they provide an ideal environment for their eggs to survive and thrive.
