HIV-AIDS, care,

Poor, access, to health, care ,

and the existence, of coexisting, infections, such as

tuberculosis, also may predispose, people, to faster, disease

progression.

The infected, person's, genetic, inheritance,

plays an important, role, and some people, are resistant,

to certain, strains, of HIV,

people, with the homozygous, CCR5-Δ32, variation,

are resistant, to infection, with certain strains, of HIV,

HIV, is genetically, variable, and exists, as different,,

strains, which cause, different, rates, of clinical, disease,

progression.

Sleep Apnea

Immine function

HIV-AIDS, care,

include, factors, that influence, the body's ability,

to defend, against, HIV,

the infected, person's, general, immune, function.

Older, people, have weaker, immune systems,

they have, a greater, risk, of rapid disease,

progression, than younger, people,

AIDS, is the ultimate, consequence, of infection, with HIV,

Cystic Fibrosis

HIV Retrovirus

HIV, is a retrovirus, that primarily, infects, vital, organs,

of the human, immune, system, such as CD4+ T, cells,

(a subset of T cells),

macrophages, and dendritic, cells,

It directly, and indirectly, destroys CD4+ T, cells.

Once the number, of CD4+ T, cells, per microliter, (µL) of blood,

drops, below 200, cellular, immunity, is lost.

Acute, HIV, infection, usually progresses, over time,

to clinical, latent, HIV infection,

then to early, symptomatic, HIV, infection, and later, to AIDS,

Chemotherapy

CD4+T cells

HIV-AIDS, care, identified, either, on the basis, of the amount of CD4+ T,

cells, remaining, in the blood,

and the presence, of certain, infections,

In the absence, of antiretroviral, therapy, the median, time,

of progression, from HIV, infection, to AIDS,

is nine, to ten years, and the median, survival, time after,

developing, AIDS, is only 9.2 months,

the rate, of clinical, disease, progression, varies widely,

between people, from two weeks up to 20 years.

Bubonic Plague

Health workers

Health, care, workers, can reduce exposure, to HIV.

Precautions, to reduce, the risk, of exposure, to contaminated,

blood.

These precautions, include: barriers, such as gloves, masks,

protective, eyeware, or shields, and gowns, or aprons, which

prevent, exposure, of the skin, or mucous, membranes, to blood

borne pathogens,

Frequent, and thorough, washing, of the skin, immediately,

after, being, contaminated, with blood, or other bodily, fluids,

can reduce, the chance, of infection,

Fibromyalgia

Needles disposed

Finally, sharp, objects, like needles, scalpels, and glass,

are carefully, disposed, of to prevent, needlestick ,injuries,

with contaminated, items,

Since, intravenous, drug, use is an important, factor in HIV,

transmission, in developed, countries,

harm, reduction, strategies, such as needle-exchange,

programmes,

are used, in attempts, to reduce, the infections,

caused by drug abuse.
