Brazil has experienced a demographic transition with population growth rates declining from 3% in the 1950s to 1.5% today. Life expectancy has increased from 42 years in 1940 to 71 years currently, though infant mortality remains high at 30 per 1000 due to poor healthcare. Botswana has the second highest HIV rate in the world at 37.3% while Brazil has a much lower rate of 0.7% due to large investments in prevention campaigns, production of generic drugs, and mobilizing civil society. Brazil is helping countries like Botswana by producing educational media, setting up factories to produce cheaper drugs, and sharing their expertise in treating HIV/AIDS.
