October 25 (Reuters) – The following is a summary of some recent studies on COVID-19. They include research that warrants further study to corroborate the results and that has not yet been certified by peer review.

COVID-19 Influenza Vaccinated Patients Have Easier Surgeries

COVID-19 patients who require surgery appear to face fewer complications if they have previously been vaccinated against the flu, new data suggests. In a preliminary study that has yet to be peer reviewed, researchers analyzed the results after various types of surgery on nearly 44,000 COVID-19 patients worldwide, half of whom had received a flu shot in the past six months. In a presentation Saturday at the American College of Surgeons annual meeting, they reported that flu vaccine patients had far fewer serious blood infections, fewer life-threatening blood clots in their veins, fewer problems with severe scarring and less heart attacks. The flu shot was also linked to lower rates of stroke, pneumonia and death. The study cannot prove that the influenza vaccines were protective, and “the influenza vaccine is in no way a substitute for the COVID-19 vaccination,” said study leader Susan Taghioff of the University of Miami Miller School of Medicine in Florida. “We strongly recommend that everyone get vaccinated against both the flu and COVID-19 this year, in accordance with current guidelines. “

COVID-19 virus spread widely undetected in early 2020

The virus that causes COVID-19 was circulating undetected in the United States and Europe as of January 2020 and was spreading long before large-scale testing was implemented, suggests a new computer model. As of March 2020, for every SARS-CoV-2 infection diagnosed in the United States, an additional 97 to 99 infections have gone undetected, according to a report published Monday in Nature. “Transmission is expected to have started in late January in California and early February in New York State, but possibly up to two weeks earlier in Italy,” said co-author Alessandro Vespignani of Northeastern University in Boston. A dearth of testing, along with narrow testing criteria, has helped the virus spread undetected, he said. “If testing had been more widespread and was not limited to a history of travel from China, there would have been the possibility of earlier detection and intervention,” Vespignani said.
