Many scientists and public health officials initially hypothesized that behavioral elements of the homosexual lifestyle multiple sex partners, for example were the cause.
Another early theory was that "poppers" amyl nitratesdrugs frequently used by some gay men to enhance sexual pleasure, were the cause CDC, MMWR, June 18, According to the report, "a laboratory and interview study of the heterosexual patients [was] in progress to determine whether their cellular immune function, results of virologic studies, medical history, sexual practices, drug use, and lifestyle [were] similar to those of homosexual patients" CDC, MMWR, June 11, One month later, the CDC reported 34 cases of opportunistic infections in Haitian patients.
All three were reported to be heterosexual males. At this time, the CDC postulated that the immune dysfunction symptoms were transmitted through blood and blood products: The clinical and immunologic features these three patients share are strikingly similar to those recently observed among certain individuals from the following groups: Although the cause of the severe immune dysfunction is unknown, the occurrence among the three hemophiliac cases suggests the possible transmission of an agent through blood products [CDC, MMWR, July 16, ].
On the same date, the FDA's Bureau of Biologics convened a meeting to discuss opportunistic infections in hemophiliacs. The CDC presented an update of the epidemic of opportunistic infections, noting that the one common thread among all groups affected i.

In addition, he asked physicians to immediately report cases of opportunistic infections or suspected acquired immune deficiency through state health departments to the CDC Foege a. At the July 16,PHS meeting, a Committee on Opportunistic Infections in Patients with Hemophilia was established to exchange information about the cases, to characterize their similarity to other risk groups, and to conduct surveillance of both hemophilia cases and antihemophilic factor AHF concentrate Public Health Service July The committee, chaired by Dr.
Foege, adopted the term "acquired immunodeficiency syndrome" AIDSand decided to focus on two goals: The reference to an "absence of symptoms" suggests that as early as the autumn of researchers were beginning to establish that the new disease might have had an asymptomatic incubation period.
Page 68 Share Cite Suggested Citation: Two of the patients were children under 10 years of age. In an accompanying editorial note, the CDC stated that the hemophilia patients had all received large amounts of a commercially manufactured anticoagulant known as AHF antihemophilic factor.
None of the patients had any prior opportunistic infections, all had been profoundly lymphopenic, and all had exhibited reversed ratios of CD4: According to the CDC, these cases provided a new perspective on AIDS by showing that children with hemophilia were at risk for the disease.
The report also stated that the number of cases was continuing to increase and that patients with hemophilia might be at significant risk for AIDS. The CDC also reported that a national survey of hemophilia treatment centers had determined that 30 percent or more of all hemophiliacs had abnormal immunological tests.
Of the reported cases, 42 5. One of the 19 donors of the blood components received by the infant during his first month of life was subsequently reported to have AIDS. The report suggested that blood transfusion was the means by which the infant had acquired AIDS.
In an accompanying editorial note, CDC stated that … if platelet transfusion contained an etiologic agent for AIDS, one must assume that the agent can be present in the blood of a donor before onset of Page 69 Share Cite Suggested Citation: None of the four infants were known to have received any blood or blood products.
The mother of one was a prostitute and IV drug user; two were the children of Haitian immigrants; and one was the child of an IV drug user mother who had died of immune deficiency. According to the report, although the nature of the immune function described in the four cases was unclear, it was possible that these infants had AIDS and that the death of one of the mothers from PCP was probably secondary to AIDS.
A few months later, some physicians, scientists, and consumers of blood and blood products endorsed the theory that blood products may be transmitting the infectious agent.Blood analysis, laboratory examination of a sample of blood used to obtain information about its physical and chemical properties.

An introduction to blood gas analysis 18 March, Blood gas analysis is a procedure that is associated with high dependency, intensive care and respiratory units, but equipment used to carry out blood gas analysis is now commonplace on hospital wards and in some community services.
Blood tests (aka blood work) can show us, obviously, what’s in our blood. (And, by extension, what’s in our bodies). That’s because blood gives us insight into what we can’t see from the outside. Blood is a transport system for the body. We carry all kinds of things in the approximately 5.
