Both were Block E residents. The first case, Miss J, was a young university graduate. She previously worked in a private tuition center but was fired after the outbreak. Having lived in AG for 20 years, she was acquainted with many Block E residents who passed away or became infected during the outbreak. She and her family members were not infected, but were quarantined in an isolation camp in April 2003.
Mrs. B, the second case, was a married woman with a 9-year-old daughter. She was one of the first batch of infected residents and experienced unpleasant treatment in hospital. She voluntarily quit her clerical job after falling ill. Because of unfair treatment in the workplace, her husband quit his job too. Her daughter was told to stop attending school owing to her status as a resident of AG.
