The worldwide quantity of new infections with hiv (Aids) fell this past year to two.67 million, based on the Not program for that disease (UNAIDS), from Berlin.

New infections are nothing more than a fifth (21%) of individuals in 1997, the company added. Also the amount of diagnoses among children fell to 390,000 cases in comparison towards the peak of 550,000 arrived at in 2001. In connection with this, UNAIDS stated that nearly 1 / 2 of women that are pregnant with Aids received medication to prevent mom-child transmission.

The agenda from the Not estimations that worldwide you will find 34 million people coping with Aids. In 2001, the general count was 28.six million. This new figure is due to the common utilization of remedies that prolong the lives of individuals who acquired the problem, that also let the hope of getting rid of the pandemic, based on UNAIDS.

“We’re near an essential milestone within the reaction to Helps,” stated the executive director from the Not entity, Michel Sidibé. “Only a couple of years, it appeared crazy to discuss the epidemic for the short term. However, science, political support and community reactions are beginning to obvious and tangible fruit,” he stated.

Based on Sidibe stated the figures reflected “a substantial growth of use of antiretroviral treatment.” Although also denote “the ongoing many new infections.”

68% of patients with Aids in sub-Saharan Africa, an area that fits only 12% from the world’s population and where there have been about 70% of latest infections.

The nation with many cases remains Nigeria, about 5.six million. However, the infections in the area also experienced a serious fall, as with Ethiopia, Nigeria, Zambia and Zimbabwe.

This past year 1.8 million people died in the disease. Based on UNAIDS, medical intervention saved 700 000 lives.

In connection with this, the Not program stated that “the Helps epidemic isn’t over yet, however the finish might be near if nations invest sensibly.” These actions could boost within the next 5 years, to attain an ambitious goal: “Aids infections zero, zero, zero discrimination and Helps-related deaths.”

In Latin America the evolution from the disease continued to be stable because the early 2000s (.4% prevalence). Additionally, it remains “stubbornly stable” The United States (.6%) and Western and Central Europe (.2%), “regardless of the universal use of treatment, care and support, and also the common awareness “the problem, stated the task.

The amount of new infections every year in Latin America, which recorded a stable decline since 1996, “stable in early many years of the brand new millennium and it has continued to be stable since that time to 100,000 each year.Inch

The report highlights the response “complete and early ‘Brazil towards the epidemic, making certain” use of prevention services and treatment which are more vulnerable and marginalized. “

Transfusions may be a means of transmission of viruses that cause serious diseases, so that while hospitals and clinics perform strict controls on blood donors, science seeks to provide increasingly effective methods to detect pathogens.

Researchers at the Institute of Molecular and Cellular Biology of Rosario (IBR) CONICET working to prevent the spread of two of the most feared virus, hepatitis C and HIV.

Are designing a new diagnostic system for blood banks to detect these viruses even when the immune system of the infected person has not yet developed antibodies to counteract them.

The time lag between infection and the appearance of antibodies called serological window period and varies depending on the sensitivity of the equipment used to detect them. In the case of Hepatitis C can take up to 69 days to 22 days for HIV.

“It follows that the hepatitis C virus is the highest risk of infection by transfusion as well as presenting the greatest serological window period, no clinical symptoms usually during the first days of infection,” said Dr. Adriana Geri , director of the research group.

Geri explained diagnostic systems typically used antibodies to identify viruses in the blood to determine if a patient is infected. Instead, the method of molecular analysis research group is developing detects viral genetic material.

“This shows whether a person is infected, even during the serological window period, or when there is still no antibodies to avoid false negative results that are,” said the researcher.

It is during this period that the virus’s genetic material is found in greater concentration in the blood and has not yet been offset by the antibodies.

Molecular analysis makes transfusions safer and more people are potential donors.

When someone responds to donate blood on a detailed questionnaire that shows if you have risk behavior or whether there situations in recent times in which the donor may have been exposed to a virus.

Based on the information provided, decide whether the person is eligible to donate and do tests to check that your blood is safe. The new diagnostic system would increase transfusion safety and to detect the virus earlier and thus shorten the serological window period.

The research group is conducting a pilot test of the test for hepatitis C in the Provincial Hospital Centennial Rosario.

“Our idea is to make a prototype test that can be transferred en masse to the effectors of health,” said Dr Geri. This research project is funded by the Federal Council for Science and Technology and the National Agency for Promotion of Science and Technology.

Another advantage of the molecular test is that it offers the possibility of releasing what the strains of hepatitis C and HIV in the region, which allows detection and appropriate treatment.

“Many of the molecular diagnostic systems using kits made in the U.S. and Europe and can not contemplate the strains circulating in our country leading to inaccuracies in the diagnosis of these infections,” said Dr. Geri.

Earlier this month, but in 1981, the first cases of AIDS in the world in Los Angeles, USA and so this year marks 30 years since the onset of the disease.

The diagnosis was younger patients who an unusual pneumonia had caused their death. The picture was produced by a microorganism called Pneumocystis, now known as Pneumocystis jiroveci, and occurred in people who had an unexplained alteration of immunity.

In that first moment, “The New York Times ran a cover story under the title” A strange disease that alters immunity could become a threat. “At that point, just know that patients with this disorder have in common that they were young men who had sex with other men.

The first articles published on the subject, realized that perhaps it was a virus that altered immunity and could be transmitted sexually, by contaminated blood and vertical transmission (from mother to child).

Later, these findings were confirmed, i.e. establishing the three routes of HIV acquisition, until in 1983 it was able to identify the virus causing the disease: a retrovirus that causes immunodeficiency, leading to the disease Acquired Immune Deficiency Syndrome, AIDS. This first phase ends when between 1984 and 1985 shows the Elisa test, which identifies early as those infected with HIV.

Conductions you are distributed in the most popular places for young people, as the field of games and popcorn.

“Love is not taken or assumed smoke …” is the slogan that carried the boxes containing miniature condoms yesterday began to share with young people in Alsatian Fair as part of the campaign of sexual health information and reproductive Association for the Prevention of Unwanted Pregnancies (Appended).

To raise awareness, guide and educate young people and break the barrier of a conservative society, the institution thought this activity so that people know about condoms and their proper use, as Teresa Gonzales, who oversees national organization. Clear that within the boxes were placed tiny balloons for children, such as those used in Carnival.

Gonzales said that apart from giving young people the “conduction”, they also deliver a “manualcito” of information with basic questions and answers and useful at the time of having sex and prevent sexually transmitted infections and HIV / AIDS . Gives also a pocket calendar.

The campaign will visit the Fair’s strategic points, such as popcorn or field of gaming, “where there are many adolescents and youth,” said the supervisor. The check the box and its contents, tore a smile more than a teenager.

For its part, Cristina Mejia, releasing of the organization, added that this idea of conductions only one of many ways of education and advice regarding the subject of Sties / HIV / Aids.

This campaign is the place every day of the Fair to its conclusion and will intensify further in Carnival, the supervisor concluded Gonzales.
