People have been advised to avoid prolonged or heavy exertion. "Go for a short walk instead of a jog and take more breaks. Stop any activity level if you experience any unusual coughing, chest discomfort, wheezing, breathing difficulty, or fatigue. If the room has windows, close them. If the air conditioner provides a fresh air intake option, keep that closed. Avoid burning of wood, candles or incense. Keep the room clean - don't vacuum. Do wet mopping to reduce dust," read an advisory issued by the Centre.
