Answer #1

Ans 1...yes it is possible.HIV virus latency period can go upto 10 to 15 years .during this period there are no symtoms and No detectable virus in the blood.AIDS is the last stage of HIV infection.

Ans 2...those who has progressed to AIDS have marked immune system involvement characteristics.those who havent progressed to AIDS may have .minor symtoms like lymphadenopathy,ulcers or opportunistic infection

Ans 3...CD4 cells carry the HIV virus.h iv virus destroy these CD4 cells and thus r3duces immunity.

Ans 4...HIV is a retrovirus.i t has RNA genome.for infecting human DNA it needs to be converted into DNA so it also has reverse transcriptase which converts it's RNA into DNA which gets Incorporated with human DNA and then multiples of the virus are produced.it also has prtoien outercoat or shell

AIDS in a 29-Year-Old Man Jason Mitchell was a 19-year-old student at the University of Oregon who had been in relatively good health throughout his life. He was a distance runner on the cross-country and track teams at the university. In the early part of January 1982 he developed a mild fever, lymphadenopathy, sore throat, and excessive fatigue, particularly after completing a training session. Although he was already thin yet fit due to his athletic regimen, he began losing weight....

One of the most noted secondary immunodeficiencies occurs with infection by the human immunodeficiency virus, or HIV. In the United States, over 1 million individuals are infected with HIV annually. HIV infects CD4 cells, also called helper T cells. The virus can remain dormant in these cells until they begin to replicate. As CD4 cells replicate the virus, the cells are destroyed, and the body’s immune responses weaken. The symptoms that appear following HIV infection are usually mild and flu-like....

1) Individuals who smoke have much higher rates of lung infection. Explain which first-line defenses mechanisms may be impaired by smoking, allowing pathogens to more readily enter the lower respiratory tract. 2) The diagnosis of tuberculosis involves the observation of lung structures called tubercles on an X ray. What immunologic process leads to the formation of tubercles, and what type of immune cells may comprise these lesions? 3) Provide an explanation in support of or refuting the following statement: "Humans...

A host organism needs time, often days, to mount an immune response against a new antigen, but memory cells permit a rapid response to pathogens previously encountered. A vaccine to protect against a particular viral infection often consists of weakened or killed virus or isolated proteins from a viral protein coat. When injected into a person, the vaccine generally does not cause an infection and illness, but it effectively teaches the immune system what the viral particles look like, stimulating...
