Emerging Infectious Diseases: MultisectoralEverything is Inter-related
Basic Definitions • Emerging Infectious Disease- disease recognized in a human host for the firsttime • Re-emerging Infectious Disease- disease that have historically occurred in human hosts, but arenow: • New geographicalarea • New resistance to medicalcountermeasures (AMR) • Reappear after apparent control orelimination (VPD)

Re-Emerging Diseases Today The World’s Largest Outbreak Ever of Cholera
Democratic Republic of Congo WASHINGTON — Torrential downpours and subsequent mudslides in the crowded capital of the Democratic Republic of the Congo, Kinshasa, earlier this week are expected to worsen the cholera outbreak that has held the country in its grasp since January 2017. The national health emergency — which, to date, has caused more than 1,000 deaths among the 53,000 confirmed cases — is the country’s worst cholera outbreak in more than two decades. Some 21 of the country’s 26 provinces are affected, and since October 2017, cases have appeared in typically unaffected regions such as the southwest region of Kasai province. There, 3.5 million lack water, sanitation, and many have been displaced by local conflict.

A Central Theme in 2018 - 100 Years1918 Influenza Global Pandemic The Influenza Pandemic of 1918 was the greatest death event of the 20th Century. It impacted the rise in life expectancy and took the lives of 567,254 Americans and between 21 and 50 million people worldwide. • https://www.prosperoanalyticsllc.com/1918-onedayatatime/ This website is an annual calendar covering influenza daily news coverage in 1918

Modern History • The start of the twentieth century, tuberculosis, pneumonia,and • diarrheal diseases caused 30 percent of all deaths in the United States. • Improvements in hygiene, sanitation, water, food,housing, • nutrition and vector control led to major declines in infectious disease mortality in theUS. • Antibiotics. Deaths from infectious disease- particularly TB and pneumonia- declined more than 8% each year from1938-1952 • By the mid-1960s, effective pertussis, polio, smallpox, tetanus, and diphtheriavaccines • Unprecedented outlay of government resources, a vastnetwork • of field epidemiologists and research scientists, and extensive cooperation from private industry (Garrett,1995) • From 1900 to 1980, annual deaths from infectious diseasehad • dropped from 797 to 36 per 100,000 persons (Armstrong etal., • 1999). By the turn of the 21st century, the average life expectancy in the United States had increased to over 76years.
ELEMENTS ONE OFSCIENCE'S MOST FAMOUS QUOTES ISFALSE ‘It’s time to close the books on infectious diseases, declare the war against pestilence won, and shift national resources to such chronic problems as cancer and heart disease’ William H. Stewart, US Surgeon General 1967 By MichaelSpecter, The New Yorker,January 5,2015
What did these Epidemic Infectious Diseases have inCommon? • All were caused by zoonoticpathogens • All spread by moderntransportation • Laboratory and clinical diagnoseswere problematic • Poor communication amongcountries • Major economicimpact
