Japan: Measles outbreak ongoing in Okinawa prefecture and Nagoya /update 1

Event

As of April 20, a total of 67 cases of measles have been confirmed in Japan. The majority of the cases have been found in Okinawa prefecture but the disease appears to be spreading north with at least two cases confirmed in the central city of Nagoya (Aichi prefecture). Japanese health officials have urged the public to get vaccinated in an effort to halt the spread of the disease.

The outbreak comes ahead of Japan's "Golden Week," so named due to the cluster of public holidays that fall during this period beginning on Saturday, April 28, and continuing through Sunday, May 6. Around 24 million people across the country are expected to travel over the course of this year's Golden Week. The measles outbreak has reportedly led some people to cancel trips to Okinawa as a precaution.

Context

The outbreak has been traced to a 30-year-old male flight attendant with Tigerair Taiwan who got infected in Thailand in March. He traveled to Okinawa for holiday between March 17 and 19, spreading the disease.

Measles is a highly contagious viral disease that typically affects mostly children. It is transmitted via droplets from the nose, mouth, or throat of infected persons. Symptoms of measles are usually a high fever, which begins approximately ten to 12 days after exposure to the virus and lasts four to seven days. A runny nose, a cough, red and watery eyes, and small white spots inside the cheeks can develop in the initial stage. After several days, a rash erupts, usually on the face and upper neck. Over the course of about three days, the rash spreads, eventually reaching the hands and feet. The rash lasts for five to six days and then fades. On average, the rash occurs 14 days after exposure to the virus (within a range of seven to 18 days). A vaccine is available.

Advice

Individuals in or planning travel to Japan are advised to ensure their vaccinations are up to date and to contact their doctor with any questions or concerns. Anyone experiencing the above symptoms is urged to seek immediate medical attention.
