Where can I find statistics on incidents of brain abcesses in men ages 20 - 30 yrs within last 10 years in US?

Yes, this is more common in men in their 40's, 50's +, but I am looking for the number of men between 20-30 yrs that have been diagnosed within say the last 10 years. Not necessarily ociated with HIV/AIDS, but also due to bacterial and/or fungal infections.
