Community Strategic Plan Los Angeles Country has a multi-million population and generally well-developed infrastructure and healthcare. However, such problems as the homeless crisis, poor environment, and the crisis of loneliness are factors that can cause serious health problems for the population. One of the most severe problems is the homelessness crisis, which leads to the fact that 60,000 thousands of people lack safe housing, adequate hygiene, and clean water (Jablon, 2020). Another problem is related to environmental pollution, which leads to lung disease and cancer due to air pollution. The third problem is the crisis of loneliness, which is caused by a shift in people’s cultural perception, manifested in the choice to remain single or unmarried for a longer time. However, there is a gap in knowledge about the direct impact of these factors on the health of the population due to the combination of factors and variables for measuring them. Most of these issues cannot be solved solely by medical interventions, since the homeless and environmental pollution problem must be met by the entire community and by structural estates initiated by local and federal authorities. However, the factor of loneliness stimulates the spread of risky sexual behavior, which leads to the spread of sexually transmitted diseases, hepatitis, and HIV. This fact can be concluded because half of single Americans seek dating, and 20% of them are looking for only casual dates, while 53% agree to both casual dates and commitments (Brown, 2020). Consequently, single people more often have multiple partners and use such applications as Tinder or Grinder to find a date. At the same time, according to Rogge et al. (2020), people who use Tinder or Grinder are prone to risky sexual behavior. Thus, one of the main concerns is the risk of transmission of both STDs and HIV due to the crisis of homelessness and loneliness in Los Angeles Country. The problem of the spread of STDs is also relevant in the world and the United States. Approximately 357 million cases of curable STDs are diagnosed annually worldwide, and although the largest number of cases occur in countries with limited access to educational and medical resources, the US also faces this problem (Gerbase & Zemouri, 2020). According to the National Center for HIV / AIDS, Viral Hepatitis, STD, and TB Prevention (2021), one in five Americans had an STD, which cost the US $ 16 million in 2018. However, disease prevention is more affordable because it includes improved information policies and access to contraceptives instead of expensive medicines to treat diseases. Therefore, prevention of risky sexual behavior among residents is a critical step for Los Angeles Country and a contribution to the national STD and HIV reduction program.
