If you are teaching you should have been vaccinated against measels and chicken pox and the whole childhood thinghie. They are regularly imported and spread among schoolchildren. The Hep A and B and whatever else they have is helpful due to bad food handling being so rampant.
There was a big hepatitis epidemic when I got here, so they strated using disposable chopsticks.

As Hepatitis A cases in Taiwan hit new record high, public urged to get vaccinated to ward off infection( 2016-05-18 )
As the number of acute viral hepatitis A cases reported in Taiwan continues to increase, the Taiwan Centers for Disease Control urges at-risk individuals, including restaurant workers, healthcare workers, caretakers of infants and children, people with chronic liver disease, hemophilia, or those who have had liver transplants, people who practice unsafe sex, people who inject drugs, and those planning to visit areas affected by hepatitis A, who do not have hepatitis A antibodies are urged to receive 2 doses of self-paid hepatitis A vaccine in order to lower the risk of infection.

Taiwan government initiated the Hepatitis B Control Program in 1982, and a series of five-year programs had been subsequently proposed and enacted. In 2011, Hepatitis B Control Program has been integrated into the Acute Infectious Disease Epidemic Risk Monitoring and Management Plan. The main strategies for Hepatitis B control include maintaining high vaccination rate, increasing hepatitis testing, and extending hepatitis treatment. A nationwide screening of pregnant women and neonate mass immunization program against hepatitis B has been implemented since July 1984. That program significantly reduced mother-to-child transmission of hepatitis B virus in Taiwan. The HBsAg positive rate of children at age six years has declined from 10.5% before the immunization program to 0.8 % in 2007, which has reached the WPRO 2017 goal of hepatitis B prevalence among young children to less than 1%. Nowadays, we still face several challenges to control hepatitis B. Immunization cannot interrupt all vertical transmissions of hepatitis B virus. Among infants born to HBeAg positive mothers, 10% will become chronic carriers of hepatitis B after even receiving immunoprophylaxis. The Hepatitis B vaccination does not provide life-long protection; therefore, vaccinees who had lost protective antibodies but had high risk behaviors may be infected with HBV if exposed. Moreover, there are numerous people living with chronic hepatitis B but unaware of their infection status and may unknowingly spread the virus to others. In addition, treatments for hepatitis B can suppress HBV replication but cannot cure the disease. We expect the above issues could be resolved in the future and look forward to further breakthroughs in hepatitis B control.
