Is PH due to an infection of the lungs?

Yes, PH can be due to infections in some patients. However, an infection is not the cause of PH in most patients.

Specific types of infection can cause PH:

  • Infection of the bowels and liver by the parasite, schistosomiasis, is a very common cause of PH around the world, but is very rare in Canada
  • Infection with HIV, the AIDS virus, can cause PAH
  • Infection with hepatitis viruses (Hepatitis B and C viruses) causes chronic hepatitis and cirrhosis of the liver, which can lead to PAH
