After decades of decline, measles is on the rise. The Centers for Disease Control and Prevention says the number of cases has spiked in the past four months – to nearly 130. In New York City, 26 people were recently diagnosed. Some of them had received the Measles vaccine in childhood.
Dr Richard Plemper leads a team developing a new oral anti-viral drug that can stop measles before symptoms begin – and could be used with the childhood vaccination. He says it can take weeks after exposure for symptoms to develop.
