We calculated there was a one in 1.4 billion chance of someone contracting vCJD from a blood transfusion. And that risk will get even smaller with time.
Dozens of bed bugs and their eggs and fecal material on a metal bed frame.
Bed bugs are pretty much universally reviled. But a public health entomologist explains how – while potentially traumatizing to deal with – they aren’t likely to make you sick.

Your blood can hold a record of past illnesses. That information can reveal how many people have had a certain infection – like 58% of Americans having had COVID-19 by the end of February 2022.

Life-saving blood is needed for everything from treating cancers and chronic conditions to helping trauma victims. But blood donations have dropped to crisis levels during the pandemic.
Sweat contains information on the condition of our bodies.
Sensors that measure sweat could be coming to the market soon, but for them to be useful, we’ll need to understand more about this fluid that our body produces.

Blood plays a vital role in keeping us alive, from delivering oxygen to the body’s organs to fighting off infections.
Capillaries are the body’s smallest blood vessels, and allow oxygen, nutrients and waste products to be delivered and removed from tissues.
European regulators are investigating a possible link between the vaccine and a second rare blood disorder.
Our bodies heal in some amazing ways. Scabs can be an important part of the healing process after we get a cut or a graze.
UK transfusion services are world-leading in being the first to take an approach based on the sexual behaviour of all donors.
