THRISSUR: Health authorities have stepped up vigil after a student at the Thrissur Government Engineering College tested positive for Shigella bacteria. The authorities have taken samples from two more students for testing, while 37 others who have developed symptoms of Shigella are under observation.
The district medical officer, Dr N K Kuttapan, said that more tests were not essential at this stage. Also, the students are by and large reluctant to get tested.
