pandemic

epidemic

idiopathic

endemic

question 7 (2 points)
human immunodeficiency virus (hiv) is spread through bloodborne transmission.
what does bloodborne transmission mean?

pathogens are spread through contact with infected respiratory droplets.

pathogens are spread through touching a contaminated object.

pathogens are spread through physical contact with a person who is infected.

Explanation:

Question 6

• Pandemic: A global outbreak, common cold is not global in a pandemic - scale spread.
• Epidemic: A widespread outbreak in a community, common cold is more constant than epidemic - level.
• Idiopathic: Means of unknown cause, common cold has known viral causes.
• Endemic: Regularly found in a population, common cold is always present in communities, so it's endemic.

Bloodborne transmission involves transfer of pathogens via blood (e.g., infected blood, blood - containing body fluids). The other options describe respiratory, fomite, or general direct contact transmission, not bloodborne.

Answer:

D. Endemic

Question 7 (assuming the last option is about blood - contact, as the visible options are cut off, but based on bloodborne transmission knowledge: Bloodborne transmission is spread through contact with infected blood, like sharing needles, blood transfusions, etc. Among the visible wrong options:

• "Pathogens are spread through contact with infected respiratory droplets" is airborne/respiratory transmission.
• "Pathogens are spread through touching a contaminated object" is fomite transmission.
• "Pathogens are spread through physical contact with a person who is infected" is direct contact (non - blood). The correct option (if present, e.g., an option like "Pathogens are spread through contact with infected blood or body fluids containing blood") would be the one related to blood contact. Since the options are cut, but based on the question, the answer should be the option that describes transmission via blood - related contact (e.g., if there was an option "Pathogens are spread through contact with infected blood, such as from shared needles or blood - to - blood contact", that would be correct). If we assume the last option (the cut one) is about blood contact, then the answer would be that option. For example, if the last option is "Pathogens are spread through contact with infected blood or body fluids that contain blood", then:
