How to Prevent Infections that Trigger Asthma or other URI infections

  • Good hygiene can decrease viral infections. Prevent the spread of infection by making sure you and your family members wash their hands regularly with soap and warm water.
  • Check with your health care provider about receiving a flu shot every year. In addition, discuss the possibility of getting a pneumococcus — or pneumonia — vaccine. Pneumococcus is a common cause of bacterial pneumonia, an illness that can be particularly serious in a person with asthma.
  • Sinusitis with asthma can be very serious. Be aware of the symptoms of a sinus infection and report them immediately to your asthma specialist to prevent asthma attacks.
  • Keep breathing equipment clean. Do not let others use your asthma medications or asthma treatment, including your asthma inhaler, asthma nebulizer, and nebulizer tubing and mouthpiece.
