Hypothesis
Host susceptibility to infection is a critical variable in assessing the emergence and spread of pathogenic microorganisms.
Conclusion
Changes in host susceptibility can lead to the emergence of new pathogens and increased public health problems.
Supporting Evidence
- Increases in diseases that cause immunosuppression are noted.
- Patients with AIDS show a significant increase in susceptibility to infections.
- The elderly are at a higher risk for foodborne illnesses.
- Malnutrition is a leading cause of increased susceptibility to infections globally.
Takeaway
Some people get sick more easily because of their health, age, or not eating well, which can help germs become a bigger problem.
Limitations
The study primarily focuses on the U.S. population and may not fully represent global trends.
Participant Demographics
The study discusses various demographics including immunocompromised patients, the elderly, and malnourished populations.
