**6. Conclusion**

Recommendations and protocols discussed above are easy to implement in countries with adequate resources, consolidated healthcare systems, and proven functional system with trained healthcare personnel and high literate population. Countries must strategically choose their models for the provision of services, taking into consideration the type of epidemics, costeffectiveness, equity in access, and available resources. The WHO at present collaborates with poor countries, proposing a "Health Systems Platform for HIV/AIDS." Such idea comprises the following areas that are considered as crucial: (1) labor systems that ensure the availability of a sufficient number of trained healthcare providers that work in an adequate facility and in safe conditions, (2) systems to purchase and distribute medications and other supplies, (3) fair funding systems to prevent people from being pushed into poverty when they become ill, and (4) healthcare information systems to alert the administrators of healthcare assistance and those in charge of elaborating policies addressing risks for persons in situations that might severely worsen. Of all these necessities, the most urgent is the availability of a sufficient number of health professionals. Nevertheless, there are some experiences gained through the participation of untrained personnel in some stages of the process; for instance, in the diagnosis of the condition of HIV carrier, this should not be de-emphasized.
