Are we facing an epidemic of harmful anal sex, brought on only because of the availability of online porn? This is what you’d think from reading a (PDF) from the Department of Culture, Media and Sport in support of the government’s aim to require all pornographic websites to use age verification by default.

ResearchGate: What were your experiences publishing research during the Ebola outbreak in 1976? 

Tuberculosis (TB) should be a disease of the past, sadly it is very much a disease of the present. We’ve known about it since ancient times yet it is the leading cause of death through a single infectious disease in the world today, causing 1.5 million deaths every year. 

In a favela in Rio de Janeiro recently, a 16-year-old girl woke up in a house she did not know, surrounded by more than thirty men, some armed, who claimed to have had sex with her. She did not remember what had happened after going to her boyfriend’s house the night before. After waking up from a drug-induced state of unconsciousness, she went home wearing men’s clothes and didn’t mention anything to her family.

Have you ever wondered why there is not an effective vaccine against tuberculosis (TB), a disease that kills one and half million people each and every year? Or why having an episode of TB does not give protection against a new infection like other diseases such a measles? The answer lies in the fact that TB is an ancient disease and the bacterium (Mycobacterium tuberculosis) has, over the millennia, evolved clever ways of evading the human immune system.

Where are you at the moment? I’m in the city of Recife, on the eastern tip of Brazil. It’s the capital of Pernambuco, the state at the centre of the Zika epidemic. Was anyone prepared for this?

Zika has caught the world by surprise. The by the World Health Organization that the recent cluster of microcephaly cases and other neurological disorders constitutes a Public Health Emergency of International Concern, shows the seriousness of the situation. The virus is transmitted by Aedes aegypti mosquitoes. Vector control should be, and is, the focus for stopping the spread of Zika. But will current control methods work?

Tuberculosis (TB) has been known to mankind since ancient times, and is likely to have caused more deaths in human history than any other infectious disease. Unlike HIV and malaria, globally rates of disease are falling very slowly and last year it once more became the leading cause of death due to a single infectious disease, causing 1.5 million deaths every year. Despite its importance, there is great uncertainty about the transmission of M.tb (the infection causing TB disease) – where it happens and who infects whom.

Babies born in poor countries can be 50 times more likely to die in their first month of life than babies born in rich countries. In the safest country in the world for newborns, Japan, 1 of every 1000 newborn babies die in their first four weeks of life. In the United Kingdom, 3 of every 1000 newborn babies die â€“ one death for every 20 babies born.

The recent image of the body of a dead three-old boy on a Turkish beach seized the world’s attention and provoked the worst nightmare of parents everywhere. , which warrants the international outrage it has received, sadly only hints at the full panorama of childhood horrors that occur around the world each day.
