There are many myths about the situation.
One out of every three people living with HIV in Latin America do not know this, mainly because of the stigma associated with this disease, because there is no culture of prevention, says Carlos Magis of Mexico's National Center for Prevention and Control of HIV / AIDS (Censida)
"There is still a delay in the diagnosis despite the fact that today the person who has been diagnosed and treated in a timely manner has a high life expectancy," said Magis, director of comprehensive care for Censida.
The doctor explained that with current treatments, the expected life expectancy is 40 years in people infected with this virus.
Brenda Krabri Ramirez, local president of the International AIDS Association (SIDA), stressed that violence, stigma and inequality for access to prevention and information have become the most important obstacles to overcoming.
"The fact is that as long as we are not fighting against this, the AIDS epidemic can not be effectively attacked," he said.
Experts say that among the least-detected people are mainly heterosexual men and the elderly.
"Especially in this second group, they slowly consider themselves at risk, because it has a great stigma for this disease," said Juan Sierra, head of the Department of Infection at the Mexican Institute of Medical Sciences and Food Salvador Zubiran.
In Mexico, according to Censida data, only 141,000 people are currently receiving retroviral treatment, and since 1996, mortality has declined, although there are still 5,000 annual deaths from this disease.
"With the treatment we offer in the Ministry of Health, patients have improved and 51% of those who are diagnosed and treated reduced the viral load by six months," Magis said.
He added that one of the disadvantages of the region is that pharmacy tests are not available to the population, which in countries like the US is available to anyone who wants to get a quick test.
He added that reducing treatment costs would be greatly helpful in countries like Mexico, where spending on HIV treatment takes one third of the Seguro Populal Disaster Fund.
"Public policies should be aimed at improving access to treatment, and one of the options is to cut costs, make a consolidated drug supply, and allow more drugs to reach Mexico," he said.
He explained that in regions like Africa, the cost of treatment is $ 100 a year, thanks to the fact that the therapy is based on generic retrovirals; while in Mexico the price rises to $ 2,000 because it is based on patent medicines.
Sierra said the HIV patient in Mexico, in spite of stigma and discrimination, has to face a hostile health system that will follow the treatment.
"Unfortunately, we have a fragmented health system and it is not very useful for people who have diseases that need to be treated for life, sometimes institutions are an obstacle to the continuity needed to treat HIV," he said.
