Study Notes
Introductory Write-up
- A pandemic is a widespread epidemic affecting a significant number of people across a large geographic area.
- Pandemics are usually caused by new microbes, with new microbes and a high susceptibility in previously unexposed populations correlating with rapid spread.
- Factors contributing to pandemic emergence/re-emergence include global travel, industrialization, urbanization, global food production, wildlife trade, deforestation, and misuse of nature.
- Socio-economic and environmental changes can lead to zoonotic diseases, which can spread and cause pandemics like the Black Death in the 14th century.
- Human vulnerability to new infections has increased due to global connectivity.
- Animal pathogens can evolve into human pathogens, leading to the loss of the original animal host and establishment of human-to-human transmission.
- Examples of predominantly human viral pathogens include smallpox, HIV, Nipah virus, rabies, West Nile virus, Ebola, Marburg, human monkey pox viruses, influenza A, dengue, SARS, and coronavirus.
- These pathogens can result in widespread outbreaks, epidemics, and pandemics.
Devastating Pandemics
- Antonine Plague (165 AD): Death toll estimated at 5 million. Cause unknown, potentially smallpox or measles.
- Plague of Justinian (541-542 AD): Death toll up to 25 million. Primarily bubonic plague, devastating the Eastern Mediterranean and Constantinople.
- The Black Death (1346-1353 AD): Death toll estimated at 75-200 million. Originated in Asia, primarily spread by fleas on rats on merchant ships, and flourished in major urban centers. Caused by the bubonic plague.
Other Pandemics
- Third Cholera Pandemic (1852-1860 AD): Death toll of 1 million. Originated in India, spreading through Asia, Europe, North America, and Africa. Identifying contaminated water as the transmission route was a key achievement.
- Flu Pandemic (1889-1890 AD): Death toll of 1 million. Also known as "Asiatic Flu" or "Russian Flu," likely caused by Influenza A virus. Significant population growth facilitated the spread, particularly in urban areas.
- Sixth Cholera Pandemic (1899-1923): Death toll of over 800,000. Originating in India, spread to the Middle East, North Africa, Eastern Europe and Russia.
- Flu Pandemic (1918): Death toll 20-50 million. Differentiated from previous outbreaks due to effects on juveniles and the elderly/immunocompromised.
- Asian Flu (1956-1958): Death toll of 2 million. Influenza A H2N2 subtype outbreak originating in China.
- Flu Pandemic (1968): Death toll of 1 million. Known as the "Hong Kong Flu" caused by the H3N2 strain of the Influenza A virus.
- HIV/AIDS Pandemic (2005-2012): Death toll of 36 million. Originated in the Democratic Republic of Congo in 1976, with significant growth and awareness, resulting in treatments and improved manageability.
- Covid-19 Pandemic (2019-present): A novel coronavirus (SARS-CoV-2) emerged in Wuhan, China, resulting in a global pandemic. This is the most cited pandemic in the provided text.
Dealing with Pandemics
- Learning from history regarding respiratory viruses, particularly influenza, emphasizes the need for global surveillance and monitoring.
- WHO's pandemic phases for planning and response, from Inter-pandemic to Pandemic phase, are useful tools for countries to understand phases and prepare.
- Preparedness for impending pandemics is crucial for minimizing loss of life and disruptions.
- Collaboration, coordination, training, communication, and leadership involvement are all critical for successful management.
- WHO plays a vital role in rapid detection, verification, and coordination in health emergencies, like pandemics, working with member states.
Role and Activities of WHO
- WHO activities in the first 48 hours of an emergency include assessment, supply deployment, communication, and activation of networks.
- WHO deploys field teams, activates global stockpiles, communicates risk assessments, activates the Global Health Cluster, and develops new technologies.
- WHO helps in strengthening public health surveillance, guidance on risk communications, laboratory service enhancement, increases domestic testing, and collaborates with international partners.
- WHO provides medical teams and maintains stockpiles for global support.
ICMR (Indian Council of Medical Research)
- ICMR plays a significant role in monitoring influenza outbreaks and predicting impending pandemics, coordinating research, and issuing timely advisories.
- ICMR conducts influenza epidemiological data gathering, surveillance system, and clinical database creation.
- ICMR also facilitates Covid-19 clinical research through a collaborative network.
Therapeutic Strategies and New Drug Development
- Development of molecules, with a focus on efficacy and reduction of side effects, require phases, systematic testing, and consideration of existing molecules as off-label uses.
- The importance of immune mediators and immune modulators in disease and treatment is addressed.
