This article does not site specific authors but it does have places to email the author and contact the site's administrators. Again, the site is in Spanish, but the sources are reliable (WHO, Intervida.org) and the information is confirmed in other sites I've seen. There are some Google ads on the site, most likely to support its upkeeping. The article was last edited on January 24, 2007 and has not been updated since. The site is written for women, so it is focused on the Intervida organization to help women and has some scary statistics to tell women to be careful.
Mery Vaca is a respected journalist who focuses on Bolivia. The page is in Spanish, but it appears to be grammatically correct and BBC Mundo is usually very high quality. She quotes activists in the issue and various sources she uses for her statistics. It was last edited on September 29, 2010. This page provides facts and focuses on a single organization for its information. It has a wide scope of the information it provides.
Anthony DePalma is a noted journalist for the New York Times, having spent time reporting from various countries in Latin America. This article is a compilation of New York Times coverage of Cuba, Fidel Castro, and US-Cuba Relations. On the right side of the page, there are links to other related sources. The page is easy to read and has a wide range of information. The New York Times is generally a very accurate newspaper, and the article was edited in July of 2010, which is definitely recent enough to have current information on what is covered in the article. This is a good background article, but there are other sources available for more specific aspects.
