Considering the second wave of Covid-19 that is holding the public in thrall, the staff of the Ambattur dialysis unit decided to do their bit for society – in addition to all that they have been and are doing for society. They put up awareness posters Wednesday, May 12, 2021, to help prevent the disease and save lives during the pandemic. The posters that talk about the need to wear masks whenever you step out, hand hygiene and social distancing, are printed in Tamil to reach the masses. The posters have been pasted at the Ambattur railway ticket counter, a fruit shop and a mobile recharge shop.
