One of the main problems of AIDS, is that a large part of the affected is unknown, so the number of infections does not stop growing. Only in our country are they produced each year close to 3,000 new infections of HIV. 60% of these cases could be avoided thanks to the early diagnostic, according to don Josep María Gatell, head of the Infectious Diseases Service of the Hospital Clínic of Barcelona, during his participation in 'Present and future challenges in HIV: towards a new paradigm?', a meeting between professionals organized by Gilead and Plataforma HIV Spain, of which Gatell is also director.
During the meeting, this expert regretted that the number of new people affected by AIDS in Spain has not declined in recent years, despite the efforts of institutions and prevention strategies carried out. However, Gatell has insisted that it is necessary to have a comprehensive and defined early diagnosis program, since today it is estimated that one in three infected does not know that they have HIV, a relevant percentage because, as pointed out by Gatell, These individuals do not take the measures they should to avoid new infections when they do not know they have the disease.
It is estimated that this 30% of undiagnosed infected could be the cause of more than 60% of new infections, which thanks to early diagnosis could be avoided. Not to mention that they would improve the treatment of those affected who do not know they have HIV, since the levels of defenses of these diagnosed late are usually lower than usual, so they require an antiretroviral treatment at the beginning.
50% of the new diagnoses are late and require an antiretroviral treatment of initiation
In this sense, the problem is that, unlike screening programs for other diseases, in AIDS the strategy to be followed is not clearly defined, neither at what time nor to which population group should HIV tests be carried out. .
There is a cultural difference in this regard between countries of the European Union, such as Spain, where HIV diagnostic tests are carried out only to those people who have clear signs that they may be infected with the AIDS virus, and other countries such as France or USA, in which the AIDS test is performed in hospitals much more frequently, which has allowed their percentages of early detection to be much higher.
