Outbreak investigation training to start soon
Concluding that weak routine surveillance was a major contributor to zika cases spiralling out of control in Madhya Pradesh, the Central government is starting a four-day surveillance and outbreak investigation training programme for state epidemiologists very soon.
“There will be two training modules on surveillance and investigation. It won’t just be zika-specific but for most communicable diseases,” said Dr BN Chouhan, director, state health department, who met the team on Friday.
“Unlike in Rajasthan, where cases were picked up in routine surveillance and intensified measures put in place immediately after the first case, things got delayed in MP as cases did not show up in routine surveillance,” said an official from the Union health ministry, requesting anonymity.
Since the first case was confirmed by the All India Institute of Medical Sciences (AIIMS) Bhopal on October 23, 128 cases of zika have been reported from six districts. Results of 16 samples sent for testing on Friday are awaited.
Bhopal, Vidisha and Sehore districts have reported 122 cases, with Sagar, Raisen and Hoshangabad districts reporting two cases each. An 18-year-old man and a 23-year-old woman who died during the corresponding period tested positive for zika, but their deaths were not documented as zika deaths as they had other more deadly infections and diseases. The man also suffered from Japanese encephalitis and the woman had uncontrolled diabetes and sepsis (severe blood infection).
The state health department officials said their routine surveillance has also been going on since June for all vector-borne diseases, including malaria and dengue. “We didn’t intensify surveillance to begin house-to-house surveys and mass testing for zika because no cases showed up in routine tracking,” says Dr Ajay Baroniya, joint director, state health department.
There were no delays at the state level, he said. “... The central team reached Bhopal on October 30 and asked us to intensify our surveillance and we immediately did so on November 1...,” said Baroniya.
Manoj Jhalani, mission director, National Health Mission, said, “The teams should have got active when three cases were reported from different places...”
