Study Notes
Infectious Disease Prevention and Treatment
- Infectious diseases are a significant global health concern, impacting communities, nations, and global populations.
- Strategies for prevention and treatment exist at individual, national, and global levels.
- Medicines have existed as long as recorded sickness.
- Biochemical approaches to disease prevention and treatment have become more prominent.
Vaccines
- Vaccines are biological preparations that improve immunity.
- Vaccines often contain weakened or killed microbes or their toxins.
- Vaccines stimulate the body's immune system to recognize and destroy pathogens.
- Vaccines have dramatically reduced the incidence of once-common diseases (polio, measles, diphtheria, etc.).
- Vaccinated individuals produce antibodies, reducing infection and transmission.
- Herd immunity protects unvaccinated individuals.
Antibiotics and Antivirals
- Antibiotics are used to fight bacterial infections by killing or inhibiting bacterial growth.
- Antibiotics used properly can save lives, but antibiotic resistance is a growing problem.
- Antivirals are used to combat viral infections by inhibiting viral reproduction or strengthening the immune response.
- Antivirals have different classes and are used for specific viral infections.
- Resistance to antivirals, like bacteria, develops over time.
- Modern medicine needs new antibiotics and antivirals due to dwindling drug pipelines.
Strategies for Development and Distribution
- The US Department of Health and Human Services' Biomedical Advanced Research and Development Authority (BARDA) develops and procures medical countermeasures for public health emergencies.
- The Patient Protection and Affordable Care Act's (ACA) has the Cures Acceleration Network promoting research and development of safe therapies.
- Other programs are promoting cooperation between philanthropists, researchers, and industry stakeholders.
Daily Habits and Prevention
- Maintaining hygiene (handwashing) is crucial for preventing disease transmission.
- Preventative measures include immunizations, food safety, and avoiding animal bites.
- Safe sex practices are vital, including testing for STIs and practicing safe sex.
- Travel precautions are required when visiting areas with high disease risk.
- Antibiotics should only be used for bacterial infections.
Public Health Surveillance
- Monitoring infectious disease outbreaks requires robust surveillance systems.
- Health providers report notifiable infectious diseases to state departments.
- State departments monitor incidence, identify potential outbreaks, and relay this data to the CDC.
- The CDC and other federal agencies also conduct surveillance; improved surveillance recommendations include national reporting systems and enhanced methods including data on absenteeism and sales of OTC medicines.
Foodborne Diseases
- Preventing foodborne outbreaks requires vigilance throughout the food production process.
- Good agricultural practices, careful food handling, and HACCP (Hazard Analysis Critical Control Point) systems are critical.
- Consolidation of food safety activities into a single agency is recommended
Global Health Efforts
- Global collaborations, especially with WHO, are critical to combat global infectious diseases
- Global surveillance programs, such as WHO's revised International Health Regulations, are essential.
- Programs and networks like ProMED and One Health Initiative aim to facilitate global efforts in disease surveillance and collaboration between human and animal health.
Developing Nations
- Infectious diseases disproportionately impact developing countries, and vaccination and treatment rates are low.
- Funding and distribution of medicine are inequitable worldwide.
- Stronger public health systems, more healthcare workers, improved sanitation, and disease surveillance are crucial for resource-poor nations.
Future Challenges
- Finding effective new medications is becoming increasingly difficult, due to high risks/costs, low profitability of antibiotic development.
- Current drug development does not address needs in developing countries.
- Social and political challenges complicate medication distribution.
