Hand hygiene may prevent which of the following? Please check all that apply.
- A.
  
  Intestinal diseases
- B.
  
  Respiratory diseases
- C.
  
  Sexually transmitted diseases
- D.
  
  Arthropod-borne diseases
- E.
  
  Skin diseases
Correct Answer(s)
A. Intestinal diseases
B. Respiratory diseases
E. Skin diseases

Explanation
Hand hygiene can prevent the spread of intestinal diseases, respiratory diseases, and skin diseases. By washing hands regularly with soap and water or using hand sanitizers, the transmission of pathogens that cause these diseases can be reduced. Hand hygiene is particularly important in preventing the spread of intestinal diseases, as fecal-oral transmission is a common route of infection. Respiratory diseases can also be prevented by practicing good hand hygiene, as respiratory droplets can be transferred from contaminated hands to the face. Additionally, hand hygiene helps in preventing the transmission of pathogens that cause skin diseases, such as fungal or bacterial infections.

Pathogenic agents may be? Please select all that apply.
- A.
  
  Bacterium
- B.
  
  Virus
- C.
  
  Protozoa
- D.
  
  Molds
- E.
  
  Yeasts
- F.
  
  Helminthes
Correct Answer(s)
A. Bacterium
B. Virus
C. Protozoa
D. Molds
E. Yeasts
F. Helminthes

Explanation
Pathogenic agents are microorganisms or substances that can cause disease. Bacteria, viruses, protozoa, molds, yeasts, and helminths are all examples of pathogenic agents. Bacteria are single-celled organisms that can cause various infections. Viruses are smaller than bacteria and can only replicate inside host cells, causing diseases such as the flu or common cold. Protozoa are single-celled organisms that can cause diseases such as malaria or amoebic dysentery. Molds and yeasts are types of fungi that can cause infections, especially in individuals with weakened immune systems. Helminths are parasitic worms that can infect humans and cause diseases like intestinal worms.

In regards to viruses, please check any of the following statements that are true.
- A.
  
  All viruses are necessarily pathogenic to humans, or animals, or plants
- B.
  
  Some viruses are absolutely indispensable to our health
- C.
  
  Viruses can reproduce in the air
- D.
  
  Viruses can reproduce in water
- E.
  
  Most viruses are useful to the environment as they recycle organic matters
- F.
  
  Viruses can survive for thousands of years in hostile environment
- G.
  
  Non-pathogenic viruses to humans may become pathogenic in some circumstances
Correct Answer(s)
A. All viruses are necessarily pathogenic to humans, or animals, or plants
G. Non-pathogenic viruses to humans may become pathogenic in some circumstances

Explanation
The statement "All viruses are necessarily pathogenic to humans, or animals, or plants" is true because viruses are infectious agents that can cause diseases in living organisms. However, it is also true that non-pathogenic viruses to humans may become pathogenic in some circumstances, meaning that they can cause diseases under certain conditions. This highlights the potential for viruses to evolve and adapt to different environments, leading to changes in their pathogenicity.

In regards to bacteria, please check any of the following statements that are true.
- A.

- C.
  
  Bacteria can reproduce in the air
- D.

- E.
  
  Most bacteria are useful to the environment as they recycle organic matters
- F.
  
  Bacterial spores can survive for thousands of years in hostile environment
- G.
  
  Non-pathogenic bacteria to humans may become pathogenic in some circumstances
Correct Answer(s)
B. Some bacteria are absolutely indispensable to our health
D. Bacteria can reproduce in water
E. Most bacteria are useful to the environment as they recycle organic matters
F. Bacterial spores can survive for thousands of years in hostile environment
G. Non-pathogenic bacteria to humans may become pathogenic in some circumstances

Explanation
Some bacteria are absolutely indispensable to our health because they play a vital role in our digestive system, immune system, and overall well-being. Bacteria can reproduce in water as they can thrive in aquatic environments. Most bacteria are useful to the environment as they help in the decomposition of organic matter, nutrient cycling, and maintaining ecological balance. Bacterial spores have the ability to survive for thousands of years in hostile environments, allowing them to withstand extreme conditions. Non-pathogenic bacteria to humans may become pathogenic in certain circumstances, such as when the immune system is compromised.
