Homework Answers
1. Spilover : The movemnt/spread of disease causing pathogen from one species to another. This is called a spilover . Also known as spilover infection or a pathogen spilover.
2. Zoonotic diseases :The diseases that is passed from an animal or insect to a human are known as zoonotic diseases or zoonoses.
3. Virus : A virus is a small collection of genetic material(DNA/RNA) surrounded by a protein coat. Viruses must infect cells and use components of the host cell to make copies of themselves. Host cells are destroyed in the process,
4.Zoonotic diesease examples:
- West Nile virus
- Plague
- Emerging coronaviruses (e.g., severe acute respiratory syndrome and Middle East respiratory syndrome)
5.Reason for the rise in zoonotic diseases:
- Human health issues
- Eating animals as food
- Wildlife management practices
- Effect of pollution on human health

In the 1990s, gene therapy was seen as a probable cure for many genetic diseases. List three reasons why it has so far been of limited success. Select the three correct statements. 1) The viral vector itself can also elicit a severe immune reaction in some individuals, which was the case in early gene therapy trials. 2) It is challenging to deliver the gene to the correct tissue to ensure proper wild-type expression. 3) It is challenging to determine the...

Health question
1. Discuss the shift from communicable diseases that once prematurely cut short life to an increased prevalence of noncommunicable chronic diseases that add years of disability. Why have these chronic diseases become more common? How have demographics contributed? (In other words, consider changes in population size and the age of populations.) What risk factors contribute to the top causes of death and disability?
