Measles have made a comeback, with outbreaks in many states. The infection is extremely contagious and can be deadly. Most people getting measles were not vaccinated against it. Adults should get the vaccine if they were born after 1957 and didn't receive two doses. They should get a booster shot if they received the vaccine between 1963 and 1968, when the vaccine used was not as strong as the one that's been given since 1968.

Sepsis causes or contributes to an estimated 20% of all deaths worldwide. The condition begins with an infection that spreads and over activates the immune system, which releases damaging inflammatory chemicals that lead to organ failure. Any infection can trigger sepsis, but those that begin in the lungs, urinary tract, gastrointestinal tract, or skin are more likely to do so. Older people are more susceptible to sepsis. The condition may be avoided by stopping bacterial or viral infections from occurring or worsening.
