The World Health Organisation has announced that Cuba has become the first country in the world to stop transmission of HIV and syphilis from mother to child. ‘Eliminating transmission of a virus is one of the greatest public health achievements possible,’ said Margaret Chan, WHO’s director general. ‘This is a major victory in our long fight against HIV and sexually transmitted infections, and an important step towards having an AIDS-free generation. WHO defines “elimination” of transmission as reduction of transmission to such a low level that it no longer constitutes a public health problem.’ A panel of international health experts visited Cuba in March and concluded that the country met the standards required for validation. In 2013, only two babies were born with HIV and five with congenital syphilis.
