Pregnant women warned as rubella patients top 1,100 in Japan

More than 1,100 rubella cases have been reported this year in Japan, raising concern about serious health impacts on unborn babies who could be infected with the disease by their mothers during pregnancy, a national institute said Tuesday.

The 1,103 cases reported this year through October 7 represent an increase of 135 from the previous week and around a twelvefold jump from the previous year, according to the National Institute of Infectious Diseases. The disease is spreading, particularly in the capital region, with 45 the largest group of the 135 cases reported in Tokyo, followed by 21 and 20 reported in Kanagawa and Chiba prefectures, respectively.

Mothers with children born with congenital rubella syndrome in the past are calling on people to get vaccinations, as infections in the early stages of pregnancy cause birth defects such as hearing impairments, cataracts and heart disorders.

“We need to keep monitoring the situation carefully to see if it will develop into a major epidemic,” health minister Takumi Nemoto said at a news conference. He also said the ministry will urge women who want to get pregnant to undergo a rubella antibody test.

In a 2012-2013 rubella epidemic in Japan, which saw more than 16,000 patients contract the disease, 45 babies developed congenital rubella syndrome and 11 of them died.

Kayo Kani, a 64-year-old co-head of a group working to stop rubella infections, warned that the latest epidemic could also result in births of babies with the syndrome, although no cases have been reported so far this year.

Seventeen years ago, Kani lost her daughter who was born with heart problems due to the syndrome. Having learned that women of her daughter’s generation are now at risk of giving birth to children with similar problems, Kani said, “I feel like my daughter is telling me to eliminate rubella infections.”

To prevent serious health repercussions arising from the contagious disease, which is often transmitted through coughing and sneezing, vaccinating people around pregnant women is important, according to the institute.

Women who are already pregnant cannot be inoculated as the vaccine itself is feared to have an impact on the child. Notable rubella symptoms are fever, sore throat, and a rash. Its incubation period is two to three weeks.

Many patients identified this year have been men in their 30s to 50s, a group that has not been vaccinated sufficiently due to changes in the country’s immunisation system. According to the Ministry of Health, Labour and Welfare, there was a period when only girls were routinely vaccinated against rubella at junior high schools, and also when the vaccination rate was low for both boys and girls because each child had to go individually to a medical institution to get the vaccination.

Know VPD! (Vaccine Preventable Diseases) Protect Our Children, a non-profit organisation promoting vaccinations to protect children, is urging the government to cover the costs of inoculating men in their 30s to 50s and importing vaccines if they are in short supply.

This year rubella has been observed from July mainly in the Tokyo metropolitan area. The weekly number of newly reported rubella patients exceeded 100 for five consecutive weeks through October 7.
