The Gujarat government denied allegations of a cover-up after the World Health Organisation yesterday disclosed three positive cases of the Zika virus in the state, which were the first such reported cases in the country. The Gujarat government has been subject to criticism over alleged delays in reporting the incident. However, health officials said that the three cases were reported from November, 2016, till February, 2017, and necessary steps had been initiated once the Indian Council of Medical Research (ICMR) alerted about the positive samples.
