“The study involved 76 healthcare workers who tested positive for the presence of SARS-CoV-2 (the virus that causes COVID-19) and 60 healthcare workers (of similar age, gender, and ethnicity) who tested negative.”

“In light of these qualities, the authors of the review suggested that zinc repletion via supplementation may be a viable means of combating pneumonia and other respiratory illnesses, including COVID-19, via zinc's capacity to reduce lung inflammation, improve airway clearance, and prevent ventilator-induced lung injury.”

“The researchers placed special focus on natural killer (NK) cells, which are part of the body's first line of defense and help detect and eliminate virus-infected or otherwise abnormal cells.”

“SARS-CoV-2, the virus that causes COVID-19, binds to a receptor on a cellular receptor called angiotensin-converting enzyme 2 (ACE2) to enter the cell and replicate. This process markedly impairs ACE2 receptor function.”

“To address this, researchers injected a harmless virus carrying a working copy of the OTOF gene directly into the cochlea, the part of the inner ear that converts sound vibrations into electrical signals the brain can interpret.”

“SARS-CoV-2, the virus that causes COVID-19, gains entry to cells via various receptor proteins, including angiotensin-converting enzyme 2 (ACE2), CD26, CD147, and neuropilin-1 (NRP-1), among others.”

“Robust evidence indicates that SARS-CoV-2, the virus that causes COVID-19, spreads primarily via respiratory droplets in the exhaled air of infected persons. Although the wearing of face masks is a critical component of global public health strategies to prevent spread of the disease, small respiratory droplets that are less than 1 micron in diameter can pass through the masks.”

“Vitamin D is a fat-soluble vitamin that plays key roles in several physiological processes, including immune function. Robust evidence demonstrates links between poor vitamin D status and severe outcomes following infection with SARS-CoV-2, the virus that causes COVID-19.”

“The authors recruited 36 healthy adult participants (average age, 52 years) who consumed little dietary fiber (fewer than 20 grams of fiber per day) and only one serving of fermented foods or less per day.”

“Signatures of donor bacteria could still be detected years later, and participants who took up more donor strains soon after treatment tended to retain more of them long term. The gut bacteriophages – viruses that infect bacteria – also showed lasting donor patterns.”
