When the cost is above its critical value so that no one 298 is engaging in prophylaxis, then this mutant cannot invade a resident population at the CSS 299ξ = √ κ. If we then decrease the cost below its critical value so that individuals begin to 300 take prophylactic measures, the CSS exploitation level decreases away fromξ = √ κ and so 301 the mutant is still unable to invade the resident population.
