All the 38 children who went to the same school at Kalady as the migrant boy who was reported with diphtheria have shown no similar trends in fever.
Health officials, who visited the houses of the children, found that they had taken regular vaccination protection.
Preventive activities
Preventive activities against diphtheria are continuing at Vazhakulam from where the 12-year-old boy from West Bengal was reported with diphtheria.
The officials also visited 241 houses in the vicinity where the migrant family was staying and enquired about the health status of all children under five years.
No reports
No one has so far reported any similar fever trend, according to a statement issued by the Health authorities.
The Health authorities provided prophylactic medicines to 25 people and the preventive TD vaccine to 52 people who had come in close contact with the boy.
Additional district medical officer S. Sreedevi told The Hindu that the boy, who is being treated at the Kottayam medical college hospital, is showing good prognosis.
His family had arrived here only four months ago, and is part of the increasing floating population in the district which has children with unimmunised status.
