2017-2018 Border Health Status Report to the legislature

HIV/AIDS


During the 2016-2017 period, the border counties had a higher rate of new cases than California. Moreover, the border region had many affected individuals who crossed the border repeatedly to seek treatment or visit family or relatives on either side of the border. In this chapter, we present two types of data: new cases of HIV for the 2016- 2017 period, and cases of previously diagnosed individuals living with HIV.

Combined data from 2016-2017 indicate that the rate for new cases of HIV was 14 per 100,000 (927 cases) among adults in San Diego County; meanwhile, in Imperial County, the rate was 14 per 100,000 (54 cases), as compared with the California rate of 13 per 100,000 (9,973 cases) (Fig. 7.1) (CDPH, 2019).

The rate of cases living with HIV in San Diego County was 417 cases per 100,000 (27,618 cases) and was 166 per 100,000 (624 cases) in Imperial County. California had a rate of 339 cases per 100,000 (267,990 cases) cases living with HIV (Fig. 7.2) (CDPH, 2019).  ​

Differences in race/ethnicity existed among new cases of HIV in the California border region. In San Diego County, African-Americans had a rate of 34 per 100,000 (107 cases), as compared with Latinos, with a rate of 19 per 100,000 (436 cases), and Whites, with a rate of 10 per 100,000 (299 cases). This same racial pattern was mirrored in Imperial County, in which the African-American population had a rate of 42 per 100,000 (four cases), as compared with the Latino population, which had a rate of 15 per 100,000 (47 cases), and the White population, which had 4 per 100,000 (two cases). As compared with the findings in California, the race disparity persisted: African-Americans had a rate of 39 per 100,000 (1,759 cases), Latinos had a rate of 15 per 100,000 (4,588 cases), and Whites had a rate of 9 per 100,000 (2,585 cases) (Fig. 7.3) (CHIS, 2016-2017).  ​

Differences in race/ethnicity existed among cases living with HIV in the California border region. In San Diego County, African-Americans had a rate of 1,140 per 100,000 (3,608 cases), as compared with Latinos, with a rate of 429 per 100,000 (9,651 cases), and Whites, with a rate of 416 per 100,000 (12,804 cases). This same racial pattern was mirrored in Imperial County, where African-Americans had a rate of 241 per 100,000 (23 cases), as compared with Latinos, with a rate of 164 per 100,000 (506 cases), and Whites, with a rate of 174 (83 cases) per 100,000. As compared with the findings in California, the race disparities persisted: African-Americans had a rate of 1,016 per 100,000 (46,122 cases), Latinos had a rate of 309 (95,949 cases), and Whites had a rate of 349 per 100,000 (105,841 cases) (Fig. 7.4) (CHIS, 2016-2017).  ​

In 2016-2017, males had a greater proportion than females of new cases of HIV in the border region and California. In San Diego County, 87% of new cases were among males (810 cases). In Imperial County, 87% new cases of HIV were among males (47 cases). Compared with the findings for California, the proportion was very similar to that in the border region, where 87% of new cases were among males (8,665 cases). In the border region, there were fewer than 16 new cases of HIV among male to female transgender individuals; in California, there were 161 new cases in the male to female transgender population, both of which represented less than 2% of total cases (Fig. 7.5) (CDPH, 2019).  ​

In 2016-2017, males had a greater proportion than females of cases living with HIV in the border region and in California. In San Diego County, 89% of cases living with HIV were male (24,539 cases). In Imperial County, 84% (526 cases) of cases living with HIV were male. As compared with the findings for California, the proportion of males living with HIV was 87% (232,961 cases). For the male to female transgender population, the proportion was less than 2% of all cases for the California border region and California (Fig. 7.6) (CDPH, 2019).  ​
