Internationally, pandemic-related stressors and social media are converging in an 'epidemic within a pandemic' of Tourettes-like tics in young people.

Cases have been reported in the United States, Colombia, Japan, South Korea and parts of Europe.

The US has now vaccinated 70% of adults with at least one shot against Covid-19, according to the latest data from the US Centers for Disease Control and Prevention, belatedly reaching a milestone the Biden administration had hoped to hit by July 4.

With infections increasing once more, and hospitalization rising among older adults, health experts offer a timely warning: a coronavirus infection can look different in older patients.

Coronavirus cases that send vaccinated people to the hospital or cause death have been relatively rare, a New York Times analysis of state data shows.

Provincetown, Mass., the quirky community at the tip of Cape Cod, thought it was safe to return to prepandemic partying. It wasn’t.

In a Times simulation, we modeled Delta-driven Covid outbreaks in two communities, one with a high vaccination rate and another with a low rate. Their levels of serious illness and death were starkly different.

As another heat wave builds in the U.S. Northwest, a New York Times analysis has found that recent scorching temperatures in the area may have been more lethal than officially reported.

Some have been used in hospitals, despite not being properly tested. But the pandemic could help make medical AI better.

A variant discovered in Colombia is now showing up in South Florida hospitals. Time and vaccination efforts will determine how quickly it could spread, experts say.

Infections in vaccinated Americans are rare, compared with those in unvaccinated people, the document said. But when they occur, vaccinated people may spread the virus just as easily.

In communities with growing caseloads, vaccinated and unvaccinated people should return to wearing masks indoors in public areas, health officials said.

COVID-19 consistently displays a higher mortality in males. This sex-specific difference in outcomes is seen not only in the current COVID-19 pandemic, but also in prior viral epidemics and pandemics. Sex hormones, such as testosterone, play a clear role ...

Some anti-vaccination groups on Facebook are changing their names to euphemisms like “Dance Party” or “Dinner Party,” and using code words to fit those themes.

Cases of the variant have popped up in several states. But neither the WHO nor the CDC considers it a variant of concern, and the fast-spreading delta variant continues to dominate U.S. cases.

Objective To estimate changes in life expectancy in 2010-18 and during the covid-19 pandemic in 2020 across population groups in the United States and to compare outcomes with peer nations. Design Simulations of provisional mortality data. Setting US and 16 other high income countries in 2010-18 and 2020, by sex, including an analysis of US outcomes by race and ethnicity. Population Data for the US and for 16 other high income countries from the National Center for Health Statistics and the Human Mortality Database, respectively. Main outcome measures Life expectancy at birth, and at ages 25 and 65, by sex, and, in the US only, by race and ethnicity. Analysis excluded 2019 because life table data were not available for many peer countries. Life expectancy in 2020 was estimated by simulating life tables from estimated age specific mortality rates in 2020 and allowing for 10% random error. Estimates for 2020 are reported as medians with fifth and 95th centiles. Results Between 2010 and 2018, the gap in life expectancy between the US and the peer country average increased from 1.88 years (78.66 v 80.54 years, respectively) to 3.05 years (78.74 v 81.78 years). Between 2018 and 2020, life expectancy in the US decreased by 1.87 years (to 76.87 years), 8.5 times the average decrease in peer countries (0.22 years), widening the gap to 4.69 years. Life expectancy in the US decreased disproportionately among racial and ethnic minority groups between 2018 and 2020, declining by 3.88, 3.25, and 1.36 years in Hispanic, non-Hispanic Black, and non-Hispanic White populations, respectively. In Hispanic and non-Hispanic Black populations, reductions in life expectancy were 18 and 15 times the average in peer countries, respectively. Progress since 2010 in reducing the gap in life expectancy in the US between Black and White people was erased in 2018-20; life expectancy in Black men reached its lowest level since 1998 (67.73 years), and the longstanding Hispanic life expectancy advantage almost disappeared. Conclusions The US had a much larger decrease in life expectancy between 2018 and 2020 than other high income nations, with pronounced losses among the Hispanic and non-Hispanic Black populations. A longstanding and widening US health disadvantage, high death rates in 2020, and continued inequitable effects on racial and ethnic minority groups are likely the products of longstanding policy choices and systemic racism.

The decline, which is the largest seen in a single year since World War II, reflects the pandemic’s sustained toll on Americans, particularly the disproportionate impact of covid-19 on communities of color.

Colorado overdose deaths increased 38% in 2020, the largest year-over-year jump since at least 2000. Fentanyl deaths more than doubled.

The highly infectious version of the virus ‘is gaining ground,’ one Southern governor warned amid an uptick of recorded infections in almost every state.

An H.I.V. infection increases the odds of dying from Covid-19 by at least 30 percent, researchers said.

The coronavirus pandemic and the continued spread of illegal fentanyl took a devastating toll on drug users, experts said, as the government reported a staggering increase in fatalities.

Leap in malnutrition during Covid shows urgent need to overhaul global food systems, report warns

Federal regulators concluded that the risk of developing the syndrome was low, and that the benefits of the vaccine still strongly outweigh it.

The SARS-CoV-2 B.1.617 lineage was identified in October 2020 in India1–5. It has since then become dominant in some indian regions and UK and further spread to many countries6. The lineage includes three main subtypes (B1.617.1, B.1.617.2 and B.1.617.3), harbouring diverse Spike mutations in the N-terminal domain (NTD) and the receptor binding domain (RBD) which may increase their immune evasion potential. B.1.617.2, also termed variant Delta, is believed to spread faster than other variants. Here, we isolated an infectious Delta strain from a traveller returning from India. We examined its sensitivity to monoclonal antibodies (mAbs) and to antibodies present in sera from COVID-19 convalescent individuals or vaccine recipients, in comparison to other viral strains. Variant Delta was resistant to neutralization by some anti-NTD and anti-RBD mAbs including Bamlanivimab, which were impaired in binding to the Spike. Sera from convalescent patients collected up to 12 months post symptoms were 4 fold less potent against variant Delta, relative to variant Alpha (B.1.1.7). Sera from individuals having received one dose of Pfizer or AstraZeneca vaccines barely inhibited variant Delta. Administration of two doses generated a neutralizing response in 95% of individuals, with titers 3 to 5 fold lower against Delta than Alpha. Thus, variant Delta spread is associated with an escape to antibodies targeting non-RBD and RBD Spike epitopes.

One dose of vaccine is not enough to protect against the Delta and Beta variants, new research suggests, and even people who have had Covid-19 should be immunized.
