HIV can have significant negative effects on individuals, nations, and the world. For individuals, HIV can cause social and economic distress as well as declining health if they cannot access antiretroviral drugs. This increases the number of infected people and burdens nations. Nations must spend large amounts of money on prevention or treatment of HIV, which can lead to economic problems. Globally, HIV is considered a pandemic by the WHO and may require international cooperation to control infection rates, though rates of death from HIV are declining in most countries. However, some countries may continue to struggle with HIV if they do not promote prevention methods like sexual education and family planning.
