The case counts in this post match the state's latest figures, but the claim that immunocompromised adults are increasing isn't something these sources measure.
The Pennsylvania Department of Health reported 1,338 confirmed cases as of its October 23 update, with more than 250 hospitalized, according to AHA News and NPR. Reports differ on deaths: NPR cites five, and other outlets cite six, including at least two infants. I couldn't confirm the post's figure of four adult deaths or its claim that adults make up two-thirds of cases. Earlier state reporting named two unvaccinated adults who died, aged 18 and 40.
The reporting I found points to unvaccinated adults, mostly aged 18 to 49, as a large share of cases. That is mainly a vaccination story. Measles is dangerous for anyone without immunity, and the post's list of higher-risk groups, including young children and people with weakened immune systems, matches standard guidance. Whether the number of immunocompromised adults is rising is a separate question. It would need registry or prescribing data, and none of these sources provide it.
