Nose signals explain why colds hit some people harder

A Yale-led study shows that how quickly nasal cells mount an interferon response to rhinovirus largely determines cold severity: a rapid response can limit infection to under 2% of nasal cells and cause mild or no symptoms, while a blocked or delayed response can let around 30% of cells become infected, leading to mucus production and inflammation. Researchers say other factors—bacteria, genetics, chronic illness, and prior immunity—also influence outcomes, and real-life confirmation is needed. The findings could eventually guide therapies that target inflammation to reduce symptoms.

Rapid Nasal Interferon Response May Stop Colds Before Symptoms Start

Lab-grown human nasal tissue reveals that an early interferon-driven antiviral defense in nasal cells can stop rhinovirus infection and prevent illness. When this response is fast, the virus is contained with few or no symptoms; if it lags, infection spreads, triggering inflammation and mucus. The findings point to therapies that boost the body's own defenses rather than targeting the virus itself.

Why a Cold Hits Some Harder: The Nasal Immune Response Holds the Key

A Yale-led study using lab-grown nasal airway organoids infected with rhinovirus shows that the severity of colds depends on the early interferon response in nasal cells; robust interferon keeps infection to under 2% of cells, while blocking interferon leads to wider infection, increased inflammation and mucus, and slower cilia, explaining why symptoms vary and suggesting that boosting interferon early could help treatments.

Recent Cold May Significantly Reduce COVID-19 Risk, Study Finds

A study suggests that recent rhinovirus infections, which cause the common cold, may reduce the risk and severity of COVID-19, especially in children, by triggering antiviral gene expression. Additionally, COVID-19 vaccines significantly reduce hospitalizations and deaths among kidney transplant and dialysis patients, while antibiotic use remains a major risk factor for C. difficile infections in hospitals. The UK reports a rise in H5N1 avian flu in poultry, and health authorities investigate travel-related measles cases in the US and Canada. Prasad resumes his role at the FDA, and the USDA deploys new measures to prevent screwworm spread.

Uncovering the Mystery Behind Your Lingering Cough

Uncovering the Mystery Behind Your Lingering Cough

A family medicine specialist explains that a lingering cough, even after testing negative for COVID-19, could be caused by one of the many respiratory viruses, such as rhinovirus, that can cause respiratory infections. Post-viral coughs, bronchitis, and post nasal drip are common culprits. It is important to follow up with a primary care doctor, especially if there is wheezing or shortness of breath. Steroids and over-the-counter medications like Flonase can help ease the discomfort, but if the cough worsens or is accompanied by chest pain or blood, immediate medical attention is necessary. This year's cases of lingering coughs and respiratory infections appear to be worse than last year's.

Uncovering the Mystery Behind Your Lingering Cough

Dr. Konstantinos Papadopoulos, a family medicine specialist, explains that a lingering cough, even after testing negative for COVID-19, is often caused by one of the many respiratory viruses, such as rhinovirus, that can cause infections. These post-viral coughs can last for weeks and may be due to factors like post nasal drip or bronchitis. It is important to follow up with a primary care doctor, especially if there are additional symptoms like wheezing or shortness of breath. While steroids and over-the-counter medications can help ease the discomfort, if the cough worsens or is accompanied by chest pain or blood, immediate medical attention is necessary. This year's cases of lingering coughs and respiratory infections appear to be worse than last year's, with an increase in RSV and a more severe viral season overall.
