A modeling study published in Science magazine on March 6, “The effect of travel restrictions on the spread of the 2019 novel coronavirus (COVID-19) outbreak,” concluded that, “In areas affected by the 2019 novel coronavirus (COVID-19), travel restrictions will only modestly impact the spread of the outbreak,” according to a press release for the study. “Based on the study’s results, the authors say the greatest benefit to mitigating the epidemic will come from public health interventions and behavioral changes that achieve a considerable reduction in the disease transmissibility – factors like early detection, isolation, and handwashing,” according to the press release. more »

In 2012, Lt. Heather Buren, along with colleagues from the San Francisco Firefighters Cancer Prevention Foundation (SFFCPF) noticed an alarming trend: In that year alone, five female firefighters were diagnosed with breast cancer. “We started asking questions, wondering what was up,” said Buren, co-author of the paper. “Cancer wasn’t new to our profession, but for the first time, I was thinking about cancer as an occupational disease: Was fighting fire somehow a contributing factor in my friends getting sick? Were our repeated exposures to toxic burning chemicals on the fire ground a factor to the high breast cancer rates among SFFD women firefighters?” more »

What is it? While the outbreak of COVID-19 in China has brought the term coronavirus into daily usage, coronaviruses can vary in severity. They can cause respiratory issues, such as pneumonia, and are believed to be one cause of the common cold. According to the Centers for Disease Control and Prevention (CDC), most people will be infected by a coronavirus at some point in their lifetimes. As of March 2020, seven coronaviruses have been identified that can cause illness in humans. Most infections result in mild to moderate symptoms, such as runny nose, headache, cough, sore throat, fever, and a run-down feeling. Coronaviruses are most commonly transmitted by coughing, sneezing, person-to-person contact, and touching objects that have viral particles on them, according to CDC. The best prevention is washing hands with soap and avoiding contact with people who are sick or work in quarantine areas. Current treatment methods are limited, and research is being fast-tracked to develop a vaccine against existing and emerging coronaviruses. more »

Dr. Nancy Messonnier: Good afternoon, thank you for joining us today. Since I last briefed you, there has been one new case of COVID-19 detected through the U.S. public health system. As has been widely reported, at this time we don’t know how or where this person became infected. This brings the number of confirmed cases of person-to-person spread in the United States to 3. We also have confirmed 2 more people who have tested positive for the virus that causes COVID-19 among U.S. citizens repatriated from the Diamond Princess cruise ship. That brings the total number of people with COVID-19 to 44 among this group of people. more »
