Understanding⁤ Measles and risk of⁢ Exposure

Measles is a highly contagious⁣ viral infection that spreads through the air when an infected person breathes, talks, coughs, or ‍sneezes. The virus ⁣can remain infectious on surfaces and in the air for several hours. Symptoms typically appear 7-21 days after exposure. Individuals who have not been vaccinated are particularly vulnerable.

Symptoms of Measles

Common symptoms of measles include:

• High fever
• Cough
• Runny nose
• Red, watery eyes
• Rash (typically appears 14-17 days after exposure)

Vaccination contributes to⁢ “herd immunity,” where a sufficiently high percentage of the population is immune, protecting ‍those who cannot be vaccinated, such as infants or individuals with certain medical conditions. The‍ current increase in cases is‍ attributed, in part, to declining vaccination rates.⁣
