  1. Poliomyelitis (Polio) By: Harsh Moolani Kristina Canary

  2. Viruses • A virus is an infectious , protein coated fragment of DNA or RNA (Bobick et. al., 2004). • Viruses replicate by invading host cells and they take over the cell’s “machinery” for DNA replication (Bobick et. Al., 2004). • Viruses include small pox, pertussis, yellow fever, chicken pox, HIV, measles, and polio.

  3. Transmission • Polio can be transferred in multiple ways and some include: • Direct person-to-person contact (NCBI, 2012) • Contact with mucus or saliva from the nose or mouth (NCBI, 2012) • Contact with infected feces (NCBI, 2012)

  4. Symptoms • General discomfort • Headache • Red throat • Slight fever • Sore Throat • Vomiting (PubMed, 2013) • Paralysis

  5. Prevalence • Prevalence with polio has fallen over 99% since 1988 (PubMed, 2013) • Only 3 world countries are polio endemic worldwide (Pakistan, Afghanistan, and Nigeria

  6. Prevention • The polio vaccine which has prevented over 90% of the polio virus (PubMed, 2013) • Don’t associate with a polio carrier • Don’t have contact with feces, or the mucus of the infected individual

  7. Treatment • Antibiotics for urinary tract infections • Moist heat to reduce muscle pains and spasms (PubMed, 2013) • Painkillers to reduce headache, pain, and spasms • Physical therapy, braces, corrective shoes, or orthopedic surgery to help recover muscle strength and function

  8. Social Impact • Over the past two decades, tremendous progress has been made toward the eradication of polio. (Bill Gates Foundation, 2012) • The polio virus was endemic in 125 countries and about 350,000 people, primarily young children, were annually paralyzed.

  9. Economic Impact • Once polio is eradicated, the world can celebrate public good that will benefit all people everywhere in the world • Eradicating polio in the next five years would save at least $40–50 billion (WHO, 2012)
