The spread of stigma is giving coronavirus a helping hand.
In the final weeks of 2019, a virus slipped furtively from animal to human somewhere in the Chinese city of Wuhan. This inauspicious moment marked the sounding of a starting pistol, unheard at first but now echoing deafeningly across the globe. The race to stop a pandemic had begun.
Climate change is not just a matter of melting ice caps and baking heat - it is also a major threat to our health. And it is a threat that will have far-reaching impacts for our children and for all future generations.
Globally, malaria deaths halved between 2000 and 2015. This was primarily achieved through the mass distribution of insecticide-treated bed nets. However, according to the most recent World Health Organization global report mosquitoes have developed resistance to the four main classes of insecticides commonly used for their control across all WHO regions with ongoing malaria transmission.
The impact of violence against women is considerable. Women often have low self-esteem and low self-confidence.

Current treatments are able to cure hepatitis C at a relatively low cost to the NHS. This provides a great opportunity to find and treat those currently infected, curing the infection before the onset of liver failure or liver cancer.

However, the way in which testing is provided needs to change in order to increase the number of people diagnosed and receiving treatment. Testing needs to be expanded to reach more people that it currently does.
