Question

A virus is an obligate intracellular parasite. In order to reproduce, a virus musit infect a host cel and coerce the host cell to manufacture more vinuses HPV is shoet for human papiliomavirus. HPV is a group of more than 150 related viruses. Each HPV virus in this large group is givennumber which called its HPV type HPV named for the warts (papillomas) some HPV types can cause. Some other HPV types can lead to cancer HPV is transmitted through intimate skin-to-skin contact. You can get HPV by having vaginal anal, or oral sex with someone who has the virus, HPV is so common that nearly all men and women get it at some point in their lives. HPV can be passed even when an infected person has no signs or symptoms. You can develop symptoms years after being infected, making it hard to know when youfirst became infected There is no way to know which people who have HPV will develop cancer or other health problems People with weak immune sytems (including individuas with HIVJAIDS)ay be less able to fight off HPV and more lkely to develop health problems from it HPV infections are so common that nearly all men and women will get at least one type of HPV at some point in their lives Most people never know that they have been infected and may give HPV to a sex partner without knowing it. Nearly 80 million Americans are currently infected with some type of HPV. About 14 milion people in the United States become newly infected each year Most people with HPV never develop symptoms or health problems. But sometimes, HPV infections wil last longer, and can cause certain cancers and other diseases.infectors can cancers of the cervix, vagina, and wlva in women; cancers of the penis in men; and cancers of the anus and back of the throat, including the base of the tongue and tonsis (oropharynx) in both women and men. Everyyear in the United States, HPV causes 30,700 cancers in men and women Cancer often takes years, even decades, to develop after a person gets HPV. The types of HP that can cause genital warts are not the same as the types of HPV that can cause cancers HPV cancer usualy does not have symptoms until quite advanced, very serious and hard to treat. For this reason, important for women to get regular screening for cervical cancer Cervical cancer screening can find early signs of dsease so that problems can be treated early before they ever turn into cancer.

Explanation / Answer

AIDS as defined as the presence of a positive HIV antibody test and one or more of the illnesses known as opportunistic infections . AIDS wasting syndrome, and three cancers -- non-Hodgkin's lymphoma, Kaposi's sarcoma , as well as cervical carcinoma -- are AIDS-defining in the presence of a positive HIV antibody test. Both HIV as well as AIDS have been continuously linked in time, place, and certain population groups as in case of children born to HIV-infected mothers since 1984. Otherwise millions of cases of AIDS, many people who are receiving cancer chemotherapy develop AIDS-like illnesses. In addition to this people receiving organ transplants, the immune system is intentional suppressed results in AIDS-like illnesses .

Many reports document the outsending of the organism to a human host which reproduces the original disease, and the consequent recovery of the microorganism in that second person. For instance, at least three laboratory workers developed AIDS subsequent to the accidental exposure to concentrated HIV in the laboratory. They all developed immunosuppression and related opportunistic diseases, including Pneumocystis carinii pneumonia after the infection. In all the above cases, HIV was isolated, sequenced, subsequently shown to be the infecting strain of the virus.

Moreover the development of AIDS after known HIV seroconversion has been occasionally seen in broadly diverse populations, including the following:

pediatric as well as adult blood transfusion cases

those hemophiliacs who had received infected blood clotting factor protein infusions

health-care workers with non intentional or other occupational exposure which are similar to the lab technicians described above

Transmission from mother-to-child

In male-to-male and male-to-female sexual transmission

In injection drug users who have secondary sexual transmission

extremely rare outbreaks

Finally, though the specific molecular mechanisms of HIV's causative role in AIDS yet not completely understood, Koch's postulates have been fulfilled, as a result establishing causality.
