Bar and restaurant terraces have become critical points for SARS-CoV-2 transmission. The high density of people, lack of cross ventilation, and consumption of drinks without masks facilitate transmission. Despite hygiene measures, the risk persists when space is limited and airflow is scarce.
Ventilation and purification systems: what is not seen in the air 🌀
Air changes per hour (ACH) is a key factor in reducing viral load. Purifiers with HEPA H13 filters capture particles of 0.3 microns with 99.97% efficiency. However, in semi-enclosed terraces with awnings and screens, natural recirculation is low. A CO2 sensor above 800 ppm indicates poor ventilation. The technical solution involves measuring, filtering, and renewing, not just maintaining social distance.
The toast that gives you a variant bonus 🥂
Nothing like raising a glass among strangers to celebrate the new strain of the week. The terrace is that magical place where you share air, coughs, and smiles with the same enthusiasm as a child at a birthday party. If the waiter also sneezes on the glasses, you have the complete package: drink, atmosphere, and a viral souvenir that money can't buy.
