SIV/SAIDS-HIV/AIDS Another Virus’ History

 

SIV/SAIDS-HIV/AIDS Another Virus’ History

(Companion piece yesterday’s post)
Viruses have their common rules, but they aren’t all the same. Covid 19 may be airborn, but HIV is not likely to be.

Some have immediate symptoms, some have intermedial delays before you know you have it, like Covid 19. And some have longer delays like HIV.

But they still are viruses in that you can be a carrier, have mild symptoms and respond to treatment, and sometimes you see the rough road. Where you are resistant to the meds, you get parasitic infections, and/or you die.

But with HIV that number is getting less and less as time and knowledge go by. It is now more commonly known as “living with” AIDS.

Like SARS Cov 2, most people who are exposed survive now.

Like SARS Covid 2, there is a separation between the virus SARS and the disease Covid 19. Between the virus HIV and the disease AIDS.

And both require you to take precautions to avoid the virus. SARS Cov 2 is to wash hands and step back, HIV is to wear a condom if you have sex with someone.

Do that and there really is no reason to panic.
But they are both pandemics.

There were approximately 37.9 million people living with HIV at the end of 2018. HIV/AIDS has actually cost more than 32 million lives so far.

And politically? There was a real failure to respond when AIDS was thought to be a “gay disease”.

Sometimes it takes more than knowledge and/or panic to deal with a pandemic.

Sometimes it takes common sense and heart. Two things that politicians are notoriously lacking in.

It always takes money and research. But most politicians would rather play tag with each other and have pissing contests than do that. It costs lives when they do that.

It’s more likely to be political failure to respond quickly that takes those lives.

……. definition of retroviruses

Retrovirus
A type of virus that uses RNA as its genetic material. After infecting a cell, a retrovirus uses an enzyme called reverse transcriptase to convert its RNA into DNA. The retrovirus then integrates its viral DNA into the DNA of the host cell, which allows the retrovirus to replicate. HIV, the virus that causes AIDS, is a retrovirus.

….. definition of lentiviruses

Lentiviruses are a family of retroviruses linked by similarities in genetic composition, molecular mechanisms of replication and in biological interactions with their hosts. They are best known as agents of slow disease syndromes that begin insidiously after prolonged periods of subclinical infection and progress slowly leading to the degeneration of multiple organ systems, cachexia (wasting) and death.

HIV-2 /Siv &
(HIV-1). These are subtypes of HIV-1:

Within group M there are known to be at least nine genetically distinct subtypes of HIV-1. These are subtypes A, B, C, D, F, G, H, J and K.

The strains of HIV-1 can be classified into four groups.Of these, M is the ‘major’ group and is responsible for the majority of the global HIV epidemic.

The other three groups – N, O and P – are quite uncommon. Group O represents up to 5% of infections in several west and central African countries, and Group N and P have been rarely identified in Cameroon. All groups can be detected by HIV-1 antibody tests.

There are Subtypes within HIV-1 group M
hybrid virus, known as a ‘circulating recombinant form’ (CRFs). Around 89 of these are known to exist.

…. contagion path of HIV

HIV can’t survive for long in the environment. When fluid leaves the body and is exposed to air, it begins to dry up. … Some research show that, even at levels much higher than usually found in the bodily fluids and blood of people with HIV, 90 to 99 percent of the virus is inactive within hours of being exposed to air. source

HIV is not spread by: Air or water. … Saliva, tears, or sweat that is not mixed with the blood of a person with HIV. Shaking hands; hugging; sharing toilets; sharing dishes, silverware, or drinking glasses; or engaging in closed-mouth or “social” kissing with a person with HIV. source
