Infectious Disease Prevention and Treatment

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.
