Inadequate insurance and limited health care may also enable the spread of syphilis. Poverty may prevent access to inclusive and premium insurance packages. This means that if you do catch syphilis, you probably won’t be able to afford the treatment even with insurance coverage. This leads to many people foregoing treatment and suffering worsening conditions.
Low-income groups, who already have a higher STD infected population also have more limited access to contraceptives and other medicines. This means that low-income people will also have a higher amount of unprotected sex, and less treatment options. This has caused mass outbreaks of STDs in low-income areas and countries.
Statistics show that male homosexual populations have a higher rate of STD transmission. Penile penetrative sex between two men increases the chance of transmission, compared to heterosexual partners wherein only the male partner commits penetration, and female homosexuals when penile penetration does not occur.
Studies have shown that lesbians have the lowest STD transmission rates, including compared to heterosexual partners. Studies have also shown that anal sex can further increase the chance of STD transmission, resulting in a higher chance of contracting syphilis caused by bacteria.
