DETROIT – Why do some COVID patients continue to suffer from symptoms months after being infected? They hope to determine why so-called “long haulers” are still suffering and what can be done to help them. “The symptoms of this include fatigue, shortness of breath, sleep disorders, fevers, GI symptoms, anxiety and depression. AdFauci said that around 30 percent of the patients who are enrolled at the University of Washington reported persistent symptoms for as long as nine months after illness. The new study will try to answer questions that include what makes people vulnerable to suffering long-haul symptoms and what’s the underlying biological cause of the prolonged symptoms.

DETROIT – Rapidly climbing case counts of COVID-19 have led to cities and counties in several states to issue new restrictions on restaurants and bars. READ: Michigan coronavirus cases up to 244,741; Death toll now at 7,929A new study is renewing concerns about the role restaurants and bars may play in helping to spread COVID-19. Researchers from Stanford University studied cell phone data from 10 U.S. cities collected from March to May of this year. They found full-service restaurants were the riskiest place for new infections, about four times riskier than gyms and coffee shops.

DETROIT – As children return to indoor classrooms and colder weather increases indoor activities for everyone, research into the way ventilation systems can help or hurt us when it comes to coronavirus (COVID-19) is important. They concluded that many modern office buildings may increase the risk of exposure to COVID-19. Many indoor heating and cooling systems have been designed to maximize energy efficiency, leading to a decreased exchange with fresh outdoor air. The very design of many ventilation systems can also contribute to contaminated aerosols staying in a room. If you’re in an office and have access to a window, open it, or at least crack it to allow fresh air in.

ANN ARBOR – A new study at the University of Michigan hopes to learn how much protection is afforded by natural infection with the coronavirus. Researchers leading the Immunity Associated with SARS-CoV-2 study are looking to enroll 5,000 U-M employees, including essential workers, first responders and those who work regularly on campus. The study hopes to examine the immunological response and risk factors to infection. “Maybe you can get infected again, but you don’t really get sick and you don’t shed virus. Results will be sent to participants throughout the study since it will use U-M pathology labs for the majority of serological testing.

Children can still become infected and spread the illness to other children and adults. But compared to older adults, children develop severe illness much less often. A new study published in the Science Translational Medicine journal looked at the immune response to COVID-19 in 65 children and 65 adults. READ: CDC says new guidance on airborne coronavirus transmission was ‘posted in error’Some children still do develop severe disease. Children infected with SARS-CoV-2 do not develop as severe illness as adults -- even among children who develop multi-system inflammatory syndrome, death is rare.

DETROIT Since the start of the coronavirus (COVID-19) pandemic, weve learned so much about the risk factors for developing severe illness from COVID-19.

The tool was built to calculate a persons risk of requiring hospitalization after they were diagnosed with COVID-19. READ: Vaping might increase risk of contracting coronavirus (COVID-19) in teens, young adultsThe study identified several risk factors that have not been seen in other models. The online tool was designed for doctors, but anyone can use it.

DETROIT A new study is looking at what it would take for colleges to reopen safely. The findings suggest frequently testing all of the students would be necessary to keep classes on campus and the coronavirus (COVID-19) under control. In the hypothetical study, all were living on campus and none had immunity to COVID-19. Testing students every two days would cost about $470 per student, per semester. Testing every two days, even with a lower-quality test, still prevented more hypothetical infections than weekly testing with a more expensive test.

DETROIT There are new reports of therapies used to treat COVID-19 every day -- often met with hopeful fanfare. Based on those two loose pieces of information, they are following a hunch and testing very high doses of famotidine in patients with coronavirus. This is science in action, but it is not anywhere near proof enough that people should even consider taking Pepcid. Although the start of these two studies generated hope and interest among the public, the bottom line is that they are nowhere near medical advice. More information on coronavirus (COVID-19):
