Similarly, Singapore’s Communicable Disease Agency (CDA) recently raised alarm over two passengers from India infected with measles who landed in Auckland, New Zealand, via Singapore Airlines. “Measles transmission may occur during travel. Travelers with fever and other overt signs of transmissible illness, such as coughing or malaise, should be strongly encouraged to delay travel while symptomatic,” the US CDC said. What Is Measles?
