I have had asthma for years, and have just increased my medication to Fostair 100/6 4 to 8 puffs a day depending on whether it is a good or bad day, 10mg of montelukast a day, and salbutamol for emergencies. I wasn't shielding last time around, but am on more medication now. Does anyone know if I am at increased risk, as work in a supermarket and there have been confirmed cases in store, and want to know how careful I should be? Thank you if anyone can advise.
