Bay Area coronavirus updates | Fri., July 31

The latest developments around the region related to the novel coronavirus, also known as COVID-19, as of Friday afternoon include:

• A Petaluma firefighter who tested positive last week for the COVID-19 coronavirus is expected to rejoin the Petaluma Fire Department next week, fire officials said Thursday. The firefighter, who the department did not identify, tested positive for the coronavirus July 23 after developing mild symptoms on July 19 during a 48-hour shift. He immediately quarantined himself, according to the fire department. In addition, 14 crew members were quarantined after having immediate, prolonged contact with the affected firefighter before he tested positive. The crew members received COVID-19 tests Tuesday and all 14 tested negative.
• A Larkspur man told Marin County park rangers this week that he was assaulted for telling a jogger on the Gertrude Ord Trail to put on a face covering to prevent the spread of the COVID-19 coronavirus. The 59-year-old Larkspur man was walking on the trail with his wife in the area of Phoenix Lake in Ross around 10 a.m. Wednesday when they encountered the jogger coming toward them from the opposite direction. The man told the jogger to put on a coronavirus mask before getting closer. The jogger subsequently shoved the man to the ground and continued running, according to Marin Municipal Water District spokeswoman Jeanne Mariani-Belding.
• Passenger traffic in June at Oakland International Airport was up more than 100 percent compared with May, but demand for air travel nationwide is again showing signs of weakening, airport officials said Friday. The number flyers jumped 141 percent in June to about 255,000, compared with about 106,000 in May.
