Preventing Malaria: A Glimmer of Hope?

A recent clinical trial tested a new approach to malaria prevention involving monoclonal antibodies.  Malaria is a parasitic disease transmitted through mosquito bites.

Mosquito-control measures, insect repellents,

Do Surgeons Who Wear N95 Masks Have Lower Oxygen Levels and Make More Mistakes?
