Sir — This refers to the editorial, “Containing Zika’s spread” (June 3). The World Health Organisation has confirmed the first three cases of Zika virus in India. We need to be on alert as Zika virus can cause an epidemic in no time.
We must not forget that Sri lanka has got the status of the second malaria-free country in the Southeast Asia region after the Maldives, in spite of its long history with the disease. India should take lessons from these two countries to eliminate the menace of deadly vector-borne diseases on a war footing.
