About 87 percent of AIDS infections in China happen through unsafe sex, said a report from the National Health and Family Planning Commission on Wednesday.

Unprotected sex also causes annual increases in the number of syphilis infections.

Despite a nine-fold increase in government spending on public health in the last decade, which reached 110 billion yuan ($18 billion)?in 2012, China has seen one new infectious disease detected every one or two years.

A total of 1,879 people died from canine madness in 2011, a 100 percent death rate, according to the report.
