TRACY K. MILLER, PHD, MPH STATE EPIDEMIOLOGIST [email protected]

OBJECTIVES

1. Identify new or re-emerging infections 2. Identify ways outside agencies can help the health department monitor for disease 3. Determine what education needs are available.

WHAT ARE "EMERGING" INFECTIOUS DISEASES?

Infectious diseases whose incidence in humans has increased in the past two decades or threatens to increase in the near future have been defined as "emerging."

These diseases, which respect no national boundaries, include: • New infections resulting from changes or evolution of existing organisms • Known infections spreading to new geographic areas or populations • Previously unrecognized infections appearing in areas undergoing ecologic transformation

WHAT ARE RE-EMERGING INFECTIOUS DISEASES?

Any condition, usually an infection, that had decreased in incidence in the global population and was brought under control through effective health care policy and improved living conditions, reached a nadir, and, more recently, began to resurge as a health problem due to changes in the health status of a susceptible population.

MEASLES

• The United States experienced a record number of measles cases during 2014, with 667 cases from 27 states reported to CDC's National Center for Immunization and Respiratory Diseases (NCIRD). This is the greatest number of cases since measles elimination was documented in the U.S. in 2000. • The majority of people who got measles were unvaccinated. • Measles is still common in many parts of the world including some countries in Europe, Asia, the Pacific, and Africa. • Travelers with measles continue to bring the disease into the U.S. • Measles can spread when it reaches a community in the U.S. where groups of people are unvaccinated.

EBOLA VIRUS DISEASE (EVD)

Ebola is a virus that causes hemorrhagic fever and is a severe, often fatal disease • Sudden onset of symptoms • Incubation period is 2-21 days (typically 8-10) Virus from the Filoviridae family Ebola has caused sporadic outbreaks in the past • 1st detected - Ebola River in 1976

POLIO Polio has been eliminated from the United States thanks to widespread polio vaccination in this country. However, the disease has been brought into the country by travelers with polio. The last time this happened was in 1993. It takes only one traveler with polio to bring the disease into the United States.

OF NOTE: From August to October 2014, CDC received increased reports of children across the United States who developed a neurologic illness called acute flaccid myelitis (AFM). • The median age of the children was about 7 years. • Almost all of them were hospitalized; some were put on breathing machines. • Most patients had fever and/or respiratory illness before onset of neurologic symptoms. • About 7 out of 10 of the children had elevated white blood cell counts, often with elevated protein levels, in their spinal fluid. • About two thirds of the children who have been observed (median 19 days) after their illness reported some improvement in symptoms, while about one third showed no improvement. Only two of the children have fully recovered. • CDC tested many different specimens but despite extensive testing, no 24 pathogen was consistently detected.

WHAT ELSE?

Hepatitis C • Outbreak here in ND; • www.ndhealth.gov/disease/Hepatitis/HCVOutbreak2013.htm • Antibiotic resistance • Selection pressure can cause resistance or it can arise endogenously by mutation or exogenously by transfer of R- factors. • one-step or multi step mutations within the organism • MRSA, VRE, CRE • Gonorhea • Salmonella • Tuberculosis • Neisseria meningitis

25

WHAT CAN WE DO?

• Judicious antibiotic use both by human and animal care providers and the public. • Reduce pressures on healthcare for antibiotics • Take antibiotics as prescribed • Conduct surveillance to watch for emergence and re- emergence of disease • Alerting healthcare providers on to watch for the unexpected. • Increase trainings and information • Improve patient history taking during illness exams • Travel should always be asked and animal exposure!! • Get vaccinated! • Take your preventative medications as directed.
