Philadelphia's infectious disease listings, 31 in all, don't cluster in one part of town. The top ZIP holds five listings, another ZIP close by holds four, and the rest thin out to one or two apiece across the remaining ZIPs on the list. That spread matters if you're trying to find a practice near a hospital campus versus one closer to home in Philadelphia.

Every one of the 31 listings has a phone number, and 29 link to a website, so calling ahead or checking a site before you go is usually possible. Paid placements would carry a Sponsored label in this category, but none of these listings have one, so what you're browsing is the plain default order, not a ranked or curated list. If you run one of these practices and notice a wrong number or a dead website link, you can claim the listing and correct it yourself, which helps someone outside the busiest ZIP actually reach you instead of hitting a dead line. Call two or three before deciding.
