<s>[INST] How often should I get tested? [/INST] The Centers for Disease Control and Prevention (CDC) recommends everyone between the ages of 13 and 64 get tested for HIV at least once as part of their routine health care. Some people, including gay and bisexual men and transgender women, should consider getting tested more often, as HIV is especially prevalent in these communities. People who are pregnant should get tested in their first trimester. Source: HRC. Link: https://www.hrc.org/resources/frequently-asked-questions-about-hiv. Field: Infectious Disease. Disease: HIV </s>
