Baby boomers are falling short in getting hepatitis C screenings. In 2012, the CDC urged the entire generation of people born from 1945 to 1965 to get this simple blood test, noting that baby boomers are five times more likely to have the virus than other adults. But a study published online March 27, 2018, by the journal Cancer Epidemiology, Biomarkers & Prevention found that only about 13% of baby boomers had been tested by 2015, up just one percentage point from 2013. The information came from national government health surveys. Hepatitis C can lead to cirrhosis, liver damage, liver cancer, and liver failure. Treatments are now available that can cure hepatitis C, if it's caught early enough. Baby boomers are believed typically to have become infected in the 1960s through the 1980s, when transmission of hepatitis C was highest. People at highest risk are those who have used intravenous drugs, had more than one sex partner, or received a blood transfusion before 1992, when the blood test for hepatitis C was first available.

Q. There has been a lot of talk about the severity of this flu season, and I recently heard that influenza also can trigger a heart attack. Should I worry?

A. Influenza is responsible for about 10,000 to 20,000 annual deaths, mostly from pneumonia or internal organ failure. In other situations, influenza infection strains a person's health, which can worsen underlying conditions, such as heart disease.

The health risks of loneliness and isolation have been known for some time, but more recently research has shown the specific effects in the brain. Finding ways to make connections with other people is the best "medicine" to alleviate the mental and physical effects of loneliness.
