International AIDS Day: What treatments are available for HIV today and how effective they are


Although no treatment for HIV infection has been found, currently available treatments in many cases allow the virus to be kept under control.

However, despite improvements, people living with this virus have an average life span of 10 years less than the rest – depending on the stage at which the presence of the virus is largely determined – UNAIDS data for 2017.

  • 35 years after the outbreak of the AIDS epidemic, how HIV carriers can have an "almost normal" life expectancy
  • At age 8, HIV-infected children grew up and could not tell anyone.

One of the challenges faced by health authorities is to improve the quality of life for people living with HIV. And for this, prevention, detection and treatment is essential.

The blood load of human immunodeficiency virus (HIV), which is a virus using a blood test or by digging into the cheek with a stick, affecting the immune system and easily disrupting the carrier, can be determined.

The tie represents the struggle of HIV.

One of the challenges of health authorities is to prevent contamination, increase access to HIV antibody tests, and improve the quality of life of HIV-positive people.

AIDS (acquired immunodeficiency syndrome) occurs when the clinical manifestations of immunodeficiency caused by HIV are very severe and our body cannot defend itself correctly.

Treatment is not necessary to develop AIDS and not to transmit the virus. These are the ones that exist today.

To protect people without viruses

PrEP (pre-exposure prophylaxis) is a daily pill that prevents HIV infection by 90% by sexual intercourse, or by 70% by the use of needles that are not sterilized or used by more than one person. It is recommended only for people without viruses and should be consulted by physicians or specialist health personnel. Which is the best option.

CaptionToday, there are drugs like PrEP that prevent the transmission of the virus, but not for everyone.

PrEp does not protect against other sexually transmitted infections such as chlamydia or gonorrhea and can sometimes cause side effects such as vomiting, nausea and dizziness.

If there is exposure to the virus

PEP (postexposure prophylaxis) is an urgent treatment for people exposed to HIV in the last 72 hours. In the event of a risky situation, the deadlines are essential as the virus takes three days to reach the immune system. Once there it begins to expand.

Treatment with PEP continues uninterruptedly for 28 consecutive days.

For people virus carriers

HIV is treated with antiretroviral drugs that work by stopping the proliferation of the virus in the body. This allows the immune system to repair itself and prevent serious diseases such as acquired immunodeficiency syndrome (AIDS) and tuberculosis.

A combination of anti-HIV drugs is used because the virus can quickly adapt to drugs and become resistant.

Condoms remain a very effective method of preventing transmission of viruses and other sexually transmitted infections.

Some treatments have a fixed dose combination in a single dose, but patients usually take one to four pills per day. The doctor chooses the most appropriate for each case.

The purpose of antiretroviral treatment is that the viral load cannot be detected in a period of three to six months from the beginning.

Having an undetectable viral load means that the patient has less risk of being infected with the virus as well as other diseases. It also reduces the risk of transmission of HIV to other people.

if He got developed AIDS

If the viral load is too high and the virus is able to damage a large part of the immune system, AIDS will emerge. The system of protection of the organism is damaged and can reduce many diseases from cold to tuberculosis.

To alleviate their effects, nucleotide analogs of reverse transcriptase inhibitors are called a type of drug that stops the proliferation of the virus and delays the spread of HIV in the body.

If there is HIV in the blood, there are different drugs that can reduce viral load.

There are a lot of brands and once again, the best will be the doctor who knows the best.

These medications may have strong side effects due to what cases and sometimes they should be combined with others to treat other diseases that contract with the deficiency of the immune system.

and how easy to get them?

Access to drugs to prevent or treat HIV is very dependent on the country.

In Latin America, as the UNAIDS Regional Director for Latin America and the Caribbean, BBC Mundo César Núñez confirmed, in Latin America, medicines for people living with HIV are free and part of the public health system.

  • What are the countries in Latin America with the latest HIV / AIDS cases?

"In Latin America, there is a benefit that reflects the legislation of every country, even in some cases, from Mexico to Chile and the HIV drugs from Argentina."

She admits that some public health systems may implement a system called katkı healing of quotas, yap in which patients make a small contribution in almost every situation.

To access the drug, Núñez may go to health centers and civilian organizations recognized by the authorities as part of the official distribution system of antiretroviral drugs.

But coverage is not the same in the entire region.

The tie symbolizes the answer to AIDS.

In all countries of Latin America, medicines for people living with HIV are covered by the public health system.

"There is no homogeneous coverage in Latin America, but it has made progress in reducing the number of treatments and the number of deaths," he said, acknowledging that sometimes drug distribution has not reached all countries or regions on an equal basis. .

According to 2017 data, there are about two million people living with HIV in Latin America and 61% are being treated. The European continent (54%) is a percentage of the global average (59%) and a few points above the coverage level.

However, not all drugs have the same coverage across the region.

"PrEP exists, but it is not generalized, it may be a more complete PrEP program in Argentina or Brazil, but in other countries, such as Ecuador, they are considered pilot experiences".

There is a dilemma here, the UN official said that scarce financial resources should be used to implement preventive drugs, or that only 100% of people living with the virus should be treated, not just 61%.

Therefore, priorities for the region are to increase the proportion of people who are continuously treated and who also improve access to virus diagnostic tests.
