Understanding the Risk and Symptoms
Measles is a highly contagious airborne disease spread through respiratory droplets produced when an infected person coughs, sneezes, or breathes. DC Health emphasizes that the Measles, Mumps, Rubella (MMR) vaccine is a highly effective preventative measure. According to the agency, nine out of 10 unvaccinated individuals exposed to measles will become infected, highlighting the critical importance of vaccination.
Symptoms of measles typically develop in two stages. The initial stage, appearing seven to 14 days after exposure, includes a fever over 101 degrees, a runny nose, red, watery eyes, and a cough. The second stage, beginning three to five days after the initial symptoms, is characterized by a rash that starts on the face and spreads throughout the body. Individuals with measles are contagious from four days before the rash appears until four days after it has surfaced.
What to Do If You Were Exposed
DC Health provides specific guidance for individuals potentially exposed. Those who have not received a measles-containing vaccine – either the MMR vaccine or a measles-only vaccine – are at risk and should contact their healthcare provider or DC Health at 844-493-2652. Immunocompromised individuals who may have been exposed are also advised to consult their doctor, particularly if symptoms develop.
Individuals who have received two doses of a measles-containing vaccine or were born before 1957 are considered protected and do not need to take action. Those with only one dose are likely protected but should discuss a second dose with their healthcare provider for complete immunity.
If you believe you have been exposed and are at risk, monitor for symptoms for 21 days. Should symptoms appear, immediate isolation and a call to your healthcare provider are crucial. DC Health advises calling ahead to any healthcare facility or emergency room to allow them to take necessary precautions to protect staff and other patients.
Rising Concerns and Misinformation
Health officials are also addressing the spread of misleading information regarding measles prevention, coinciding with rising case numbers reported by the Centers for Disease Control and Prevention across the United States. This underscores the need for reliable information and continued efforts to combat vaccine hesitancy and protect public health.
