Could dog detectives sniff out malaria?

Dr James LoganBy Dr James Logan, Senior Lecturer in Medical Entomology at the London School of Hygiene & Tropical Medicine and Director of ARCTEC.  Dogs have a highly sensitive sense of smell, making them great at nosing out illegal drugs or prohibited imports. However, it’s not just crime fighting these dog detectives assist us with. They can also turn their paws to healthcare, as their noses are able to pick up on the subtle odour changes in humans when some diseases cause slight biochemical changes in our bodies. Read more

Why are thousands of sugarcane workers in northwestern Nicaragua dying from chronic kidney disease?

Dr Marvin GonzalezBy Dr Marvin Gonzalez, Department of Non-Communicable Disease Epidemiology at the London School of Hygiene & Tropical Medicine; and Research Centre on Health, Work and Environment at the National Autonomous University of Nicaragua-León. In the sugarcane fields of Nicaragua, young men work in the scorching heat for 8-12 hours a day cutting down lofty canes with a machete. It’s backbreaking work – in a typical shift they may lose more than 2kg in body weight. The men drink water or electrolyte drinks and take respite in the shade when they can, but this is often not possible. Such physically demanding work can be expected to have a toll. But increasingly worrying numbers of them are being struck down with chronic kidney disease of unknown cause, a long-term condition which will eventually take many of their lives. Read more

The government cited my research in its campaign against porn and anal sex – here’s why I disagree

By Dr Cicely Marston, Senior Lecturer in Social Science at the London School of Hygiene & Tropical Medicine. 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 recent policy note 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.

Can we eradicate TB by 2035?

By David Moore, Professor of Infectious Diseases and Tropical Medicine at the London School of Hygiene & Tropical Medicine. 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.  Read more

New clues in the fight against tuberculosis

Taane ClarkBy Taane Clark, Professor of Genomics and Global Health at the London School of Hygiene & Tropical Medicine and Dr Ruth McNerney from the University of Cape Town.   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. To make an effective vaccine we first need to understand the tricks employed by the bacteria to allow them to survive and thrive within the human body. Read more

Will current mosquito control methods halt the spread of Zika?

By Dr Laith Yakob and Dr Thomas Walker Zika has caught the world by surprise. The declaration 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? Read more
