What does this mean - roam in sunlight without breaking lockdown rules. Can do suryanamaskar to scortching Sun. Alas, isopropyl alcohol (rubbing alcohol or propan-2-ol or isopropanol or 2-propanol) is not drinkable - but can be used for cleaning hands & face with care!
If sunlight is able to kill them then during summer they may not be able to travel long distances unless helped by wind. Let us hope will be eliminate virus before rainy season.
