Last week, the US Centers for Disease Control and Prevention (CDC) has confirmed close to 400 individual cases of measles in 2019. CNN reported that this is the second-largest number of reported cases since 2000, when the disease was declared to be eradicated. Here, in the Jewish community, we often hear about cases in our communities of individuals traveling to Israel and unfortunately bringing back the virus with them. However, these cases are not restricted to the Jewish community. The CDC reports that in addition to New York and New Jersey, measles outbreaks (defined as three or more cases) are ongoing in California and Washington State. Individual cases have also sprouted in 10 other states across the country.
