New Delhi : The Aedes mosquito has another sinister implication for Delhi, in addition to being the pest that transmits the dengue and chikungunya viruses. The confirmation of 13 cases of Zika virus among Indians in Singapore has raised the risk of the infection spreading across the country, and Delhi is at highest risk not only because of its being an international travel hub, but also because Aedes aegypti, the vector for Zika virus transmission, already has a strong presence here.
“The threat of the Zika virus spreading is more potent now than ever before,” worried a senior doctor at AIIMS. “The government should step up screening of travellers from nations affected by the disease. It will be difficult to stop the virus’ spread otherwise.”
