The US Centers for Disease Control and Prevention (CDC) yesterday reported 22 more imported Oropouche virus cases, raising the national total to 74 in five states. So far, 1 case of the neuroinvasive form of the disease has been reported. Most of the illnesses are in Florida, which has reported 70 cases. The Florida Department of Health (Florida Health) said in its latest weekly arbovirus report that all of the state's cases involve travel to Cuba, one of the newly affected countries in the Americas experiencing an outbreak. Florida has reported cases in 11 counties, but most have been in Miami-Dade County. (Schnirring, 9/18)

Patients who are overweight when they're first diagnosed with cancer may be at higher risk of developing a second cancer. Investigators at the American Cancer Society looked at data on nearly 27,000 people who were diagnosed with cancer. They found that compared to cancer survivors with a normal BMI, those who were overweight were 15% more likely to be diagnosed with a second primary cancer. Those who were obese were 34% more likely.

The tiny electronic devices remain a vital means of communication in some areas - such as healthcare and emergency services - thanks to their durability and long battery life. "It's the cheapest and most efficient way to communicate to a large number of people about messages that don't need responses," said a senior surgeon at a major UK hospital, adding that pagers are commonly used by doctors and nurses across the country's National Health Service (NHS). "It's used to tell people where to go, when, and what for." Many pagers can also send out a siren and then broadcast a voice message to groups so that whole medical teams are alerted simultaneously to an emergency, a senior doctor in the NHS said. That is not possible with a mobile phone. (9/19)
