Emerging Infectious Diseases

What It Is

Emerging infectious diseases are defined as infectious diseases that are newly recognized in a population or have existed but are rapidly increasing in incidence or geographic region.
Factors contributing to emerging infectious disease include population growth, spread in healthcare facilities, aging population, global travel, and changing vector habits related to
climate change. Infectious diseases are one of the leading causes of death worldwide.

The amount of a particular disease that is usually present in a community is referred to as the baseline or endemic level of the disease. Endemic refers to the constant presence and/or
usual prevalence of a disease or infectious agent in a population within a geographic area. Sometimes, the amount of disease in a community rises above the expected level. Epidemic refers to an increase, often sudden, in the number of cases of a disease above what is normally expected in that population in that area. Outbreak carries the same definition of epidemic but is often used for a more limited geographic area. Pandemic refers to an epidemic that has spread over several countries or continents, usually affecting a large number of people. Emerging infectious diseases have pandemic potential and pose significant global risk.

A community health resilience approach emphasizes prevention and planning measures that individuals and families can take to secure their physical, emotional, and mental health and wellbeing in times of crises. A critical component in preparing for pandemics and infection disease hazards is immunization.

People of all ages should stay up to date with the recommended vaccines. When people are not vaccinated, they are at increased risk for diseases and can also spread diseases to others in their community.

COVID-19 and flu vaccines are recommended people 6 months and older. To find a vaccine, visit www.vaccines.gov. For more information about immunizations visit Fairfax County Health Department’s page: https://www.fairfaxcounty.gov/ health/immunization or call 703-246-2411 | TTY 711

For adults, the Centers for Disease Control and Prevention (CDC) last updated the recommended immunization schedule in 2022. Follow these three simple steps to immunization:

  1. Consider recommended vaccinations by age.
  2. Discuss with your healthcare provider the vaccinations you may need based on your health history.
  3. Schedule your vaccination appointments as recommended by your healthcare provider.

For children, comply with school immunization requirements, updated by the Virginia Department of Health in 2022. The Code of Virginia requires children entering daycare, public and private schools to give proof of vaccination before enrolling in school. More information about requirements is available on the Health Department website - https://www.fairfaxcounty.gov/ health/immunization/child.

Recommended vaccines for children include:

  • HepB Hepatitis B vaccine
  • DTaP Diptheria, tetanus, and pertussis vaccine
  • Hib Haemophilus influenza type b vaccine
  • IPV Poliovirus Vaccine
  • HepA Hepatitis A vaccine
  • MMR Measles, mumps, and rubella vaccine
  • VAR Varicella Vaccine
  • PCV Pneumococcal Conjugate Vaccine
  • Tdap Tetanus, diptheria, and pertussis vaccine
  • MenACWY Meningococcal Conjugate Vaccine (ACYW)
  • HPV Human Papillomavirus Vaccine
