A two-member central public health team has told the Calcutta Municipal Corporation that it would like to visit some containment zones to assess surveillance and suggest improvements, officials of the civic body said.

The duo are from the All India Institute of Hygiene and Public Health in Calcutta.

“We have no problem if they visit the containment zones or the worst-affected pockets. We will seek permission from Swasthya Bhavan (the headquarters of the state health department),” said a CMC official.

The central team also wants to know figures like how many of those surveyed by the CMC’s surveillance team showed symptoms of influenza.
