Question

which mode of transmission involves airborne dust particles carrying pathogens over long distances?
biological vector transmission
droplet transmission
direct contact
vehicle transmission
question 57 (1 point)
florence nightingales work during the crimean war mainly contributed to which field?
public health and hospital hygiene
genetic epidemiology
disease etiology
immunology

Explanation:

For the first question:

• Biological vector transmission involves living organisms (like mosquitoes) carrying pathogens.
• Droplet transmission is when pathogens are spread in droplets (e.g., from coughing) over short distances.
• Direct contact is pathogen transfer through physical contact.
• Vehicle transmission can involve inanimate objects (like dust particles) carrying pathogens over long distances.

For the second question:

• Florence Nightingale focused on improving hospital conditions (e.g., sanitation) during the Crimean War. This is related to public health and hospital hygiene.
• Genetic epidemiology deals with genetic factors in disease distribution.
• Disease etiology is the study of disease causes.
• Immunology is about the immune system.

Answer:

First question: Vehicle transmission
Second question: Public health and hospital hygiene
