MADRID, Spain — Clinical experiences in approaching COVID-19 from different perspectives, results obtained by various therapeutic options and, above all, the challenges posed by a new healthcare reality — long COVID — were all the focus of a recent discussion at the 7th International Congress of the Spanish Society of Precision […]
Clostridioides difficile infection (CDI) is often confirmed through toxin testing, yet toxin tests alone may not be sufficient for diagnosing and guiding treatment decisions for patients with CDI. Dr David Lyerly “The presence of a toxigenic strain does not always equal disease,” said David Lyerly, PhD, during a session on C difficile toxin […]
A South African study based on blood samples found that the BA.4 and BA.5 sub-lineages of Omicron were more likely to evade antibodies produced by previous Omicron infections than the immunity provided by vaccinations. Scientists took blood samples from 39 people infected with Omicron, with 24 people not vaccinated and […]
New data from two different sources on cardiac complications linked to COVID-19 have shown that such issues are low overall, but are higher after infection than after vaccination. The new information comes from the Centers for Disease Control and Prevention’s (CDC’s) National Patient-Centered Clinical Research Network (PCORnet), and from a separate […]
An analysis of data from nearly 154 000 US veterans with SARS-CoV-2 infection provides a grim preliminary answer to the question: What are COVID-19’s long-term cardiovascular outcomes? The study, published in Nature Medicine by researchers at the Veterans Affairs (VA) St Louis Health Care System, found that in the year after recovering from the illness’s […]
The Omicron subvariant BA.2 is replacing its sister version, BA.1, as the dominant form of SARS-CoV-2 in many countries, which has led scientists to wonder whether the COVID-19 pandemic is about to throw these regions into disarray yet again. But a study published on 13 March shows that mRNA vaccines offer a similar degree […]
It is a great mystery of infectious disease: Why are some people seemingly unaffected by illness that harms others? During the COVID-19 pandemic, we’ve seen this play out time and time again when whole families get sick except for one or two fortunate family members. And at so-called superspreader events […]
Following the emergence of the Delta variant, individuals who had a prior COVID-19 infection with or without vaccination had lower case rates than those who were vaccinated alone, data from California and New York found. “Infection-derived protection was higher after the Delta variant became predominant, a time when vaccine-induced immunity […]
he negative impact of COVID-19 on patients’ health has been recognized but not yet clearly quantified. Previous research has looked at the effects of the disease at 6 months, and scientists have now explored the impact on overall health at 12 months. The relative increase in the risk of death after COVID-19 […]
Three meters are not enough to ensure protection. Even at that distance, it takes less than five minutes for an unvaccinated person standing in the breath of a person with COVID-19 to become infected with almost 100 percent certainty. That’s the bad news. The good news is that if both […]
