ON THE RELATIONSHIP BETWEEN THE SPREAD OF STD AND SEXUAL FREEDOM IN A SOCIETY

Abstract

STD is transmitted by coitus. Hence, the spread of the disease will be influenced by sexual freedom in a society. The quantitative relationship between them is analyzed here. When αβμ' φ' < 1, the STD will subside eventually, while when αβμ' φ' ≥ 1, it is possible to spread explosively where
μ'= ?? (σ²+μ²-μ), φ'= ?? (σ²+φ²-φ)
μ and σ₁ are the mean and standard deviation of p(k)
φ and σ₂ are the mean and standard deviation of q(k)
α: communicability of STD from man to woman and
β: that of STD from woman to man.
Here, p(k) is defined as the probability distribution of men in a society who have k sex partners and q (k), that of women.
