Developments in the measles outbreak that has spread across the nation.
The Center of Disease Control and Prevention said the outbreak is about to spread even further over the Easter holiday weekend — when more people are traveling.
To date, there have been at least 465 cases of measles reported in 20 states, including New York, Washington, New Jersey, Michigan and California.
These outbreaks are linked to travelers who brought measles back from other countries such as Israel, Ukraine, and the Philippines — where large measles outbreaks are occurring.
Meanwhile, a man from Brooklyn who traveled to Israel — now named patient zero — unknowingly spread measles to at least 39 people.
Infected individuals may experience symptoms such as mild fever, cough, runny nose, and red eyes, according to CDC public health officials.
The symptoms then worsen to a rash that usually appears on the face, neck and upper chest.
Experts also say the highly contagious disease can attack 9 out of 10 people who are exposed to the measles virus.
