Due to NIHs all-hands-on-deck response to the pandemic, researchers at NIDCR were able to quickly pivot and apply their expertise in oral biology and medicine to answering key questions about COVID-19, said NIDCR Director Rena DSouza, DDS, MS, PhD. Bad breath may also be a sign of dry mouth. For cell infection, SARS-CoV-2 requires the binding to a surface cell receptor for the spike protein, which is identified in the angiotensin converting enzyme (ACE)-2 protein, and the proteolytic action of hosts proteases like TMPRSS2 [24,25]. As the virus has evolved, smell or taste loss has become more rare, but it's still reported, say the scientists behind the COVID Symptom Study. Fatigue. Muscle or body .
