Influenza

A nasal spray delivering a broad-spectrum antibody has demonstrated potential to prevent infections from any flu strain in animal and preliminary human studies. Developed initially by Johnson & Johnson and now advanced by Leyden Labs, the spray could offer rapid protection during pandemics. Experts see it as a valuable tool for high-risk groups, though further testing is needed.

Hong Kong is approaching the winter flu season, but vaccination rates among most age groups remain below the 70 per cent threshold needed for herd immunity, a leading government medical adviser has warned. David Hui Shu-cheong on Saturday reminded the public to get vaccinated ahead of Lunar New Year, when social gatherings are frequent.

A mutation of the influenza A virus, known as the H3N2 K subclade, has led to increased hospitalizations in Europe and the United States, though no more severe cases are reported. In Latin America, including Mexico, preventive surveillance is in place without this variant predominating. Authorities recommend vaccination for vulnerable groups amid the risk of spread.

An international team led by ETH Zurich and including researchers in Japan has used a new high‑resolution imaging technique to watch, live, as influenza viruses penetrate human cells. The work shows that cells actively engage with the virus, helping to draw it inside in a process that resembles surfing along the cell membrane, and could inform the development of targeted antiviral therapies.

Severe flu cases are rising in Brazil's Southeast region and beginning to spread to Bahia, according to Fiocruz's Infogripe bulletin. The influenza A virus is the leading cause of deaths from Severe Acute Respiratory Syndrome (SRAG) in the country so far. The data covers epidemiological week 44, from October 26 to November 1.

Researchers have found that the H5N1 avian influenza virus can survive in raw milk cheese made from contaminated milk, even after the FDA's required 60-day aging period. Highly acidic cheeses, such as feta, showed no detectable virus, highlighting acidity's role in safety. The study, published in Nature Medicine, also indicates that while drinking contaminated milk can infect animals, eating the cheese does not.
