Nasal spray contains a chemical that can inactivate the coronavirus.

The nasal spray contains a chemical that can inactivate the coronavirus spike protein, which was produced by researchers at the University of Helsinki in Finland. TriSb92, the novel molecule, has been demonstrated to protect against coronavirus infection for at least eight hours in cell cultures and animal trials, even in circumstances of high exposure risk.

In contrast to vaccination protection, TriSb92's action begins very immediately after it is given.

Leading Western experts believed a lab leak in Wuhan was the 'likely' origin of Covid.

New Delhi, Jan 12 (IANS): Leading Western experts believed a lab leak in Wuhan was the 'likely' origin of Covid but were silenced because it could cause harm to Chinese scientists, bombshell emails show, the Daily Mail reported. Sir Jeremy Farrar, who publicly denounced the theory as a 'conspiracy', had admitted in a private email in February 2020 that a 'likely explanation' was that the virus was man-made.

The then-UK government advisor said at the time he was '70:30 or 60:40' in favour of an accidental release versus natural origin, the report said. In the email, sent to American health chiefs Anthony Fauci and Francis Collins, Farrar said it was possible that Covid had been evolved from a Sars-like virus in the lab. He went on that this seemingly benign process may have 'accidentally created a virus primed for rapid transmission between humans'.

Covid has resulted in significant liver damage in some cases.

According to a new study done by academics at the University of Tennessee, up to 11% of Covid-19 users had liver co-morbidities.

During the course of the disease, 14% to 53% of people had higher levels of liver enzymes such alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Increased levels of liver enzymes may indicate that a person's liver has been damaged, at least briefly. Covid has resulted in significant liver damage in some cases. Swelling of the liver, jaundice (yellow discoloration of the eyes and urine), and failure of liver function tests are the most prevalent.

Researchers from Yale University have developed a passive air sampler clip that can help assess personal exposure to SARS-CoV-2

Masks, social distancing, proper hygiene and ventilation can help reduce the transmission of Covid-19 in public places, but even with these measures, scientists have detected airborne SARS-CoV-2 in indoor settings. Now, researchers from Yale University have developed a passive air sampler clip that can help assess personal exposure to SARS-CoV-2, which could be especially helpful for workers in high-risk settings, such as restaurants or health care facilities.

The researchers developed a wearable passive air sampler, known as the Fresh Air Clip, that continually adsorbs virus-laden aerosols on a polydimethylsiloxane (PDMS) surface. Described in ACS' Environmental Science & Technology Letters, the clip is a small, lightweight, inexpensive and wearable device that doesn't require a power source.

Covid-19 is primarily transmitted through the inhalation of virus-laden aerosols and respiratory droplets that infected individuals expel by coughing, sneezing, speaking or breathing.
