According to this resource:

one does not capitalize seasons. See number 5 on that list.

In this sentence, the word "HIV" and the title "Reverend" should be capitalized.

To determine if a word should be capitalized, there are a few rules to consider:

1. Proper nouns: Capitalize the names of specific people, places, organizations, and things. In this case, "HIV" is an abbreviation for Human Immunodeficiency Virus, a specific virus, so it should be capitalized.

2. Titles: Capitalize titles when they are used as a form of address or as part of someone's name. In this sentence, "Reverend" is a title used before a person's name, so it should be capitalized.

3. Capitalizing the first word of a sentence: The first word in a sentence is always capitalized.

Remember that there are exceptions and specific style guidelines for capitalization, depending on the language, context, and style manual being used.
