What to do now

Stay indoors and only go out if you really need to.
Shut doors and windows tightly and block gaps with damp towels.
Outside, cover nose and mouth with a mask or damp cloth and change it often.
Do not rub your eyes. Wear protective glasses if you must be outdoors.
People with asthma or lung disease should stay inside and take medicine as prescribed.
Avoid open spaces at the peak of the storm and when visibility is poor.
Wash your face, nose and mouth often.
