Question: How common is Streptococcus pneumoniae?

  1. Hi pnemono,

    Well hopefully James will have a clearer answer, because all i am going to say is that it is the most infectious agent leading to hospitalisation in the world.

    Hopefully James has some stats?


  2. Thanks Dustin,
    It currently infects 99.99% of the worlds population and that is conservative, it more than likely lives in everyone. The vast majority of the time it does nothing and you both live happily but if you get sick with something else, sometimes, S. pneumoniae will try to take advantage of that situation and jump into you lungs, then blood, then brain if possible.
    It is the leading cause of lower respiratory infection (lung infections), blood infections and meningitis (brain infection) world wide. Kills more children under 5 years of age every year than anything else and puts the largest burden on child health when compared to any other bacterial or viral pathogen on the planet. Very common and because it is so common it only has to go badly 1% of the time to cause a huge amount of disease and death.
