HIV/AIDS is likely to impact on individual business operations:

organisational disruption (staff turnover, skills loss, declining morale)
(ii) Increased costs – recruitment, training, insurance cover, health
costs, funeral costs (where businesses provide this), supplying cheap/free aid (e.g. pharmaceutical companies).3
Another concern for companies is that they may be forced tocompensate for government policy shortcomings. Those businessesthat are affected by HIV/AIDS will need to have different responsesdepending on the quality of government response to the problemby the countries in which they operate. As a result of the importanceof a country’s response to the issue, many companies are attemptingto include the domestic government in their HIV/AIDS strategies. They understand that they need to work with the government toensure an effective, holistic response to the disease. Many companiesare weighing up the benefits of internal programmes against relianceon public health programmes in the host country of their operations. However, while 50% of business leaders expect the disease to havean effect on their operations within five years, less than 10% havetaken steps to conduct a quantitative HIV/AIDS risk assessment.4
Responses which have been identified as recommended action forcompanies operating in areas of high disease incidence include3:-
• Create workplace policies to ensure help for infected employees
• Provide grants to HIV/AIDS organisations;
• Encourage other key players (public and business sectors) to get
