Common lung infection in infants has different subtypes with differing asthma risks

Common lung infection in infants has different subtypes with differing asthma risks

Credit: Pixabay/CC0 Public Domain Bronchiolitis—the most common lung infection in young children, and which is most often caused by respiratory syncytial virus, or RSV—is the leading cause of hospitalizations in U.S. infants, and about 30% of those with severe bronchiolitis later develop asthma. A team led by investigators at Massachusetts General Hospital (MGH) has uncovered …

What makes the elderly more susceptible to SARS-CoV-2 infection?

Why is severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of COVID-19 (coronavirus disease 2019), biased towards infecting the aged population? A recently published study by Italian scientists linked aging, DNA damage, telomere shortening, and increased levels of angiotensin-converting enzyme 2 (ACE2) to this relationship. To better understand the modulation of the ACE2 …

Vaccination reduces the risk of severe COVID-19 infection

Credit: Unsplash/CC0 Public Domain However, adults who are frail, living in areas of high deprivation or have unhealthy lifestyles are more at risk of COVID-19 infection and getting ill, despite being vaccinated, compared to other vaccinated people. Researchers at King’s College London analyzed data from participants logging their symptoms, tests and vaccines on the UK …

SARS-CoV-2 infection detected in a poodle living with a COVID-19 positive family

The coronavirus disease (COVID-19) pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), first emerged in Wuhan City, China, in December 2019. The virus is thought to have originated in horseshoe bats and jumped to as yet unverified intermediate hosts before spilling over to human hosts – a process known as zoonosis. Now, …

Study links blood cell mutations to increased infection risk with age

Study links blood cell mutations to increased infection risk with age

Credit: Susanna Hamilton, Broad Communications New research suggests age-related changes in blood cell chromosomes are a marker of impaired immunity. A person’s risk of severe infections increases dramatically as they grow older, but scientists do not yet understand how age might be linked to weakened immunity. Now, research shows that certain age-related changes in blood …

Skin Disorders associated with the COVID-19 Pandemic: A Review. Image Credit: Maridav / Shutterstock

Skin disorders on the rise during COVID‐19 pandemic due to infection and PPE use

An increase in personal protective equipment (PPE) use and hygiene measures such as the use of hand sanitizers, hand washing, and mask usage during this pandemic have increased the frequency of dermatological diseases. Additionally, there are many exanthems and cutaneous issues associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection itself.  Moreover, adverse dermatological …

Study observes broad and invariable memory B cell response following SARS-CoV-2 infection

Even as vaccine roll-outs against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues in a number of countries worldwide, there has been considerable skepticism as to whether they elicit immunity against the newly emerging variants of concern (VOCs). Even more, there are unanswered questions as to how long immunity will last, and whether it …

Seroprevalence study of SARS-CoV-2 infection in domestic cats

Along with humans, dogs and cats have tested positive for COVID-19 (coronavirus disease 2019). In spite of this, we don’t know for certain whether pets are involved in the transmission of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). To date, SARS-CoV-2, the etiological agent of COVID-19 has infected over 173 million individuals and claimed …

Maternal SARS-CoV-2 infection imprints immune response in the newborn

Maternal SARS-CoV-2 infection imprints immune response in the newborn

Pregnant women have a higher risk of developing severe coronavirus disease 2019 (COVID-19) if they are infected by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The effect on the fetus, however, is less clear. A new bioRxiv* preprint research paper reports the immunological footprint in the newborn left by maternal infection with SARS-CoV-2 during …
