'A buildup of coronavirus in the lungs is likely behind the steep mortality rates seen in the pandemic, a new study finds. The results contrast with previous suspicions that simultaneous infections, such as bacterial pneumonia or overreaction of the body's immune defense system, played major roles in heightened risk of death, the investigators say. Led by researchers at NYU Grossman School of Medicine, the new study showed that people who died of COVID-19 had on average 10 times the amount of virus, or viral load, in their lower airways as did severely ill patients who survived their illness.
Our findings suggest that the body's failure to cope with the large numbers of virus infecting the lungs is largely responsible for COVID-19 deaths in the pandemic," says study lead author Imran Sulaiman, MD, Ph.D., an adjunct professor in the Department of Medicine at NYU Langone Health.'

So this paper suggests viral clearance/control is still important even during late stage disease and contributes to mortality. In a cohort of mechanical ventilation patients, 142 patients were given a bronchoscopy procedure to collect lung samples. Deceased patients had 10 times more viral load than survivors. Previously general consensus was viral load during severe Covid stage was lower and there has been a focus on inflammatory/secondary infections. This paper advises anti-viral drugs should be continually used throughout the disease course.
This is obviously good news for SNG001 as it gives a good reason for the drug working in the hospital setting.
