Pathogen Vector Host

What are the three main types of pathogen vectors?

• mechanical vectors, biological vectors, and airborne vectors

• static vectors, dynamic vectors, and stationary vectors

• viral vectors, bacterial vectors, and fungal vectors

• waterborne vectors, foodborne vectors, and contact vectors

Label the host, vector and virus

a

Who is hosting the virus or pathogen?

Who is spreading the virus?

Where is the virus or pathogen?

How do vectors contribute to the spread of infectious diseases?

• Vectors have no impact on the spread of infectious diseases

• Vectors help to eliminate infectious pathogens

• Vectors can carry and transmit infectious pathogens.

• Vectors only spread non-infectious diseases

Explain the concept of reservoir hosts in the context of host-pathogen interactions.

• Reservoir hosts are organisms that harbor a pathogen without showing any signs of disease, and can serve as a source of infection for other hosts.

• Reservoir hosts are organisms that only carry non-infectious pathogens

• Reservoir hosts are organisms that actively seek out pathogens to infect other hosts

• Reservoir hosts are organisms that are always immune to all pathogens

What is the difference between treating a vaccine and bacteria?

• Vaccines are used to treat bacterial infections, while antibiotics are used to prevent diseases.
• Vaccines stimulate the immune system, while bacteria are treated with antibiotics.
• Vaccines kill bacteria, while antibiotics stimulate the immune system.
• Vaccines and bacteria are both treated with antibiotics.

How can vaccines help fight a virus?

• By stimulating the immune system to produce antibodies
• By increasing the risk of infection
• By causing the immune system to shut down
• By making the virus stronger
