Question

One only needs to break one link in the chain of infection to prevent the spread of disease. Which link do you think would be the easiest to break to prevent the most recent influenza virus (H1N1) and why? Your answer must include the name of a link on the chain and a reasonable explanation for why that would work. Include how the flu is transmitted. Be sure to cite and reference your sources. Note: Some people refer to intestinal illness as the “flu.” It is not. I am referring specifically to the influenza respiratory virus (H1N1) for this assignment.

INFECTIOUS DISEASE Any microorganism that can cause a disease such as a bacterium, virus, parasite, or fungus. Reasons that the organism will cause an infection are virulence (ability to multiply and grow), invasiveness (ability to enter tissue), and pathogenicity (ability to cause disease). RESERVOIR The place where the microorganism resides, thrives, and reproduces, i.e., food, water, toilet seat, elevator buttons, human feces, respiratory secretions. PORTAL OF EXIT The place where the organism leaves the reservoir, such as the respiratory tract (nose, mouth), intestinal tract (rectum), urinary tract, or blood and other body fluids. MODE OF TRANSMISSION The means by which an organism transfers from one carrier to another by either direct transmission (direct contact between infectious host and susceptible host) or indirect transmission (which involves an intermediate carrier like an environmental surface or piece of medical equipment). PORTAL OF ENTRY The opening where an infectious disease enters the host's body such as mucus membranes, open wounds, or tubes inserted in body cavities like urinary catheters or feeding tubes. SUSCEPTIBLE HOST The person who is at risk for developing an infection from the disease. Several factors make a person more susceptible to disease including age (young people and elderly people generally are more at risk), underlying chronic diseases such as diabetes or asthma, conditions that weaken the immune system like HIV, certain types of medications, invasive devices like feeding tubes, and malnutrition.

word count needs to be 350

Answer 1

4th link of chain ( mode of transmission) is easiest form to break and pervent dease transmission

For example - mosquito bite cause dengue fever

1st I'm not able to kill dengue virus

2nd I'm not able to kill reservoir

3rd - I'm not able to pervent exposed

4th - I'm able to kill mosquito and pervent transmission

In influenza ( H1N1) break the 3rd step of chain (portal of exit)
