According to the health department, none of the people who were infected had been vaccinated. Health officials said measles is highly contagious and can be life-threatening, especially in children younger than 5 years old.
Officials said the virus spreads through the air when an infected person coughs or sneezes.
Some of the symptoms include a fever over 101 F, cough, runny nose, red, watery eyes, and a rash, and can appear seven to 14 days after contact with the virus.
