Marilyn Stebbins, 58, of Davis, a UC San Francisco pharmacist, will tell her story, announced webinar organizer-moderator Walter Leal, UC Davis distinguished professor of the Department of Molecular and Cellular Biology, College of Biological Sciences and former chair of the UC Davis Department of Entomology.
The webinar, to include experts in immunology, infectious diseases, pathology and emergency medicine, is free and open to the public. Registration is underway at http://zoompresentation.com, where advance questions can be submitted. The webinar also will include live questions.
Looking back, Stebbins related she began getting coldlike symptoms prior to a family skiing trip to Sandpoint, Idaho. An airline flight took her and her husband from Sacramento to Spokane, Wash. Upon returning home, she sought medical care for what she thought was the flu. She was tested for COVID-19 on March 3, and was informed March 4 she was positive. She was hospitalized for three days with what she calls the “worst illness I've ever had.”
In her story, “My COVID-19 Journey,” which appears on the UCSF School of Pharmacy website, https://bit.ly/2x1pqIe, Stebbins describes herself as “a healthy, fit, 58-year-old woman who enjoys distance trail running, weekly circuit training, and Pilates. I'd completed a 30K trail race just before the departure date for my vacation and looked forward to a 50K race two weeks after my return home.”
Controversy erupted when a Yolo County Health Department press release inaccurately described her as “an older woman with underlying health conditions.”
Stebbins said her symptoms included headache, diarrhea, nausea, coughing, and chills but “I never had a fever.” Family members, including her husband, who were with her on the skiing trip, have not contracted the disease.
The webinar is expected to draw a widespread audience. Chancellor Gary May will give the introduction. The main speakers are UC Davis physician-scientists Emanuel Maverakis, Stuart Cohen and Nathan Kuppermann; UC Davis veterinarian-scientist Nicole Baumgarth; physician Ron Chapman, Yolo County Health Officer; and pediatrician State Sen. Richard Pan, District 6 chair, Senate Committee on Health.
UC Davis distinguished professor James R. Carey of the Department of Entomology and Nematolgoy will share his scientific modeling expertise. UC Davis You-Lo Hsieh, distinguished professor, UC Davis Department of Biological and Agricultural Engineering, and an expert on textiles and clothing, will explain the differences between regular masks, surgical masks, and N95 masks.

Integrated pest management specialist Frank Zalom, distinguished professor of entomology, UC Davis Department of Entomology and Nematology, and plant pathologist Mysore "Sudhi" Sudarshana with the U.S. Department of Agriculture's Agricultural Research Service, based at UC Davis, organized the webinar. The event is supported by the Regional IPM centers as part of the U.S. Department of Food and Agriculture's National Institute of Food and Agriculture (NIFA).
Registration is underway at https://attendee.gotowebinar.com/register/536624718414291457
GRB and the virus associated with it have been confirmed in many major grape production regions of the United States and Canada, said Zalom, the lead author of the newly published Regional Pest Alert on the North Central IPM Center website. Several research teams across North America, Zalom said, “have been intensely characterizing the disease and effects on grapevines, as well as characterizing the virus, its spread and potential management” since the discovery of the virus in 2011.
Zalom cited considerable progress, “but much remains unknown. Speakers representing many of the labs will present their work and what it means for the grape industry.”
“Red leaf symptoms that differed from other known red leaf diseases affecting grape foliage were first noticed in vineyards planted with red wine grape cultivars in Napa County, California, in 2008,” he wrote in the Regional Pest Alert. “A virus now known as Grapevine Red Blotch-associated virus (GRBaV) was subsequently identified in grapevines exhibiting red blotch symptoms in 2011. It is now confirmed that red blotch disease is present in many major grape production regions of the United States and Canada.”
