Arizona Resident Dies from Plague, First Death Since 2007

A resident of northern Arizona has died from pneumonic plague, marking the first death from this form of plague in the U.S. since 2007. Plague is a rare bacterial infection primarily spread through fleas and contact with infected animals, but pneumonic plague is the most deadly and contagious form, affecting the lungs. The incident highlights the ongoing risk of plague in rural western states, though it remains a treatable disease with antibiotics.

Persistent Infectiousness in Children: Study Finds 40% Remain Contagious Post-Symptom Resolution

A study conducted in Toronto during the Omicron surge found that 40% of children with COVID-19 were still infectious on the day after their symptoms resolved. The study also revealed that rapid antigen tests (RATs) were often negative early in the course of illness and cannot be relied upon to exclude infection. The findings suggest the need for infection prevention and control interventions for up to 10 days post-symptom onset to reduce transmission risk, especially around vulnerable or immunocompromised populations.

Covid-vaccinated children show similar infectious duration as non-vaccinated, study reveals

A study conducted in California found that children who have been vaccinated against Covid-19 are infectious for the same duration as their non-vaccinated peers. The study, which analyzed viral shedding in children aged seven to 18, revealed that both vaccinated and non-vaccinated children were infectious for an average of three days. The findings raise doubts about the necessity of Covid booster shots for children. However, the study did not assess the vaccines' ability to prevent initial infection. The low uptake of booster doses among children is attributed to parents' perception that the benefits of vaccination do not outweigh the risks, as children are less likely to experience severe illness from Covid-19.

Expert warns of potential pandemic deadlier than COVID.

The next pandemic could be as infectious as COVID-19 but far more lethal, according to Dr. Robert Wachter, chair of the Department of Medicine at the University of California in San Francisco. While COVID-19 has caused over 1.1 million deaths in the US alone, it generally killed under 5% of the people it infected. Wachter warns that there's nothing to say a virus couldn't be as infectious as COVID-19 but far more lethal. Other experts have also raised the possibility of an equally transmissible but more lethal pandemic pathogen.

"New Highly-Infectious COVID-19 Variants with Unique Symptoms Detected in Multiple States and Countries"

The highly-infectious Arcturus variant of COVID-19, first detected in New York in January, has now been identified in 27 states. The variant, believed to be one of the most infectious versions of Omicron to date, is a "recombinant" of COVID subvariants BA.2.10.1 and BA.2.75. The World Health Organization has been monitoring the variant since late March and has expressed concern about its potential to become not only more transmissible but more severe. However, population-level immunity from vaccination and past infection may help mitigate the impact of future waves of infection.

The 'Arcturus' COVID Variant Spreads Across 27 States with New Symptoms.

The highly-infectious Arcturus variant of COVID-19, first detected in New York in January, has now been identified in 27 states, including California, New Jersey, Connecticut, Massachusetts, Pennsylvania, Virginia, and Maryland. The World Health Organization has labeled it a "recombinant" of COVID subvariants BA.2.10.1 and BA.2.75 and warns that it is one to watch. The virus continues to evolve, and there is concern that it could become not only more transmissible but also more severe. Population-level immunity from vaccination and past infection may help reduce the size of future infection waves.

Revived 'Zombie Viruses' from Permafrost Pose Modern Threat.

Scientists have discovered that "zombie viruses" found in permafrost, some of which are tens of thousands of years old, can infect amoeba cells once revived. The viruses were found in seven permafrost samples from ancient Siberia and were in a dormant state for between 27,000 and 48,500 years. As permafrost melts due to climate change, viruses capable of infecting humans may emerge, and the release of organic matter frozen for up to a million years could further enhance the greenhouse gas effect.
