Tolerating, not fighting, viruses a viable survival strategy

18 septiembre 2014

In ecology, disease tolerance is defined as a host strategy not to fight a pathogen tooth and nail, but rather tolerate it to live (and survive) better in the long term. One key feature of tolerance is that the disease only progresses very slowly — if at all — even if the host carries a high pathogen load. In some HIV sufferers, this approach is evident. A research team has now determined how strongly patients differ in their tolerance and upon which factors it depends.
