"The index patient in the second super-spreader outbreak was an individual on hemodialysis for chronic renal failure who had diarrhea and, on two occasions, stayed with his brother in Block E in the Amoy Gardens residential complex.30, 31 Amoy Gardens has 19 residential blocks, with eight apartments on each of the 33 floors.31 In several bathrooms from block E, it was reported that the U-shaped traps linking the vertical drainage pipes, known as risers, to the sanitary fixtures, did not function properly. As a result, when water flowed down, the backflow from the risers was able to generate aerosols and spread pathogens into individual bathrooms. In addition, powerful window fans installed by residents in many bathrooms created a significant negative pressure that amplified the aerosol backflow. In the Amoy Gardens complex outbreak, 329 individuals were infected and 42 died."
