HIV/AIDS: THE IMPACTS ON THE BUSINESS SECTOR AND HOUSEHOLD AND COPING STRATEGIES

CHAPTER 1: IMPACT OF HIV/AIDS ON THE BUSINESS SECTOR

Introduction
AIDS (Acquired Immune Deficiency Syndrome) is caused by the Human Immunodeficiency Virus (HIV). In order for the virus to attack a person's immune system, it has to enter the bloodstream, and there are three ways in which this may occur: 1.Through sexual intercourse - this includes both heterosexual and homosexual intercourse, although most infections in the developing world are transmitted heterosexually. 2.Directly into the bloodstream through use of contaminated blood or blood products, or sharing of intravenous drug-injecting equipment. 3.From mother to child - it is estimated that about one third of infants born to infected mothers will be infected. This may occur prior to birth across the placenta, during birth, or via breast milk. The possible responses to the epidemic are well documented. Risk of sexual transmission can be reduced by use of condoms and/or cutting down on numbers of partners and treating other sexually transmitted infections. Blood and blood products can be made safer through screening of donors and their blood. Drug users can be encouraged to sterilize or refrain from exchanging needles. Work on developing means of reducing mother to child infection is underway. One of the crucial points that have to be made about the HIV/AIDS epidemic is that it is different from most other epidemics and diseases, and consequently requires a different and much broader response - one which must encompass far more than the health sector. The factors that make it unique are: •It is a new epidemic. AIDS was first recognized as a specific condition only in 1981 and it was not until 1984 that the cause (and a test to detect it) was identified. •It has a long incubation period. Persons who are infected by the virus may have many years of productive normal life, although they can infect others during this period. It is not certain how long this latent period is; estimates range from five to fifteen years, with the shorter period being found in the developing world, where people are less healthy and not well nourished. It is known that good health and nutrition, and early treatment of opportunistic infections, will extend the period of a healthy and productive life. Unfortunately infected children will, for the most part, die before their fifth birthdays. •The prognosis for people infected with HIV is bleak. At the end of the incubation period, a person will usually experience periods of sickness increasing in severity, duration and frequency, until he/she dies. •The disease is found mainly in two specific age groups: children under five and adults aged between 20-40 years. For various reasons there seem, in the developing world, to be slightly more females than males infected, and women develop the disease at a younger age. •The scale of the epidemic is also different from most other diseases. As Table 1 shows, in some settings, up to 30 percent of ante-natal clinic attendees are infected. This means that between 20-25 percent of sexually active adults may be infected. •HIV is mainly sexually transmitted, which means it is passed on through one of the most fundamental human activities, but one with which we are neither open nor comfortable to talk about. •There are links between HIV and other diseases, most notably tuberculosis, which has further implications to public health. •In general, the epidemic is still spreading in the developing world, although there are signs that the level of infection may have peaked in some areas.
