Things have been looking up for the U.S. now than we have a responsible, knowledgeable president with competent advisers. But we we’re still in danger as long as the worldwide pandemic rages in other countries. Right now India isin the spotlight. We also need to deal with the anti-vaxxers and the Trumpists who refuse to accept vaccines. We’re also still learning about the long-term effects of Covid-19 as well as how the disease is transmitted.
How bad is this pandemic? Maybe worse than the 2018 flu, reports The New York Times: How Covid Upended a Century of Patterns in U.S. Deaths.
A surge in deaths from the Covid-19 pandemic created the largest gap between the actual and expected death rate in 2020 — what epidemiologists call “excess deaths,” or deaths above normal.
Aside from fatalities directly attributed to Covid-19, some excess deaths last year were most likely undercounts of the virus or misdiagnoses, or indirectly related to the pandemic otherwise. Preliminary federal data show that overdose deaths have also surged during the pandemic.
A New York Times analysis of U.S. death patterns for the past century shows how much 2020 deviated from the norm….
Since the 1918 pandemic, the country’s death rate has fallen steadily. But last year, the Covid-19 pandemic interrupted that trend, in spite of a century of improvements in medicine and public health.
In the first half of the 20th century, deaths were mainly dominated by infectious diseases. As medical advancements increased life expectancy, death rates also started to smooth out in the 1950s, and the mortality rate in recent decades — driven largely by chronic diseases — had continued to decline.
In 2020, however, the United States saw the largest single-year surge in the death rate since federal statistics became available. The rate increased 16 percent from 2019, even more than the 12 percent jump during the 1918 flu pandemic….
Combined with deaths in the first few months of this year, Covid-19 has now claimed more than half a million lives in the United States. The total number of Covid-19 deaths so far is on track to surpass the toll of the 1918 pandemic, which killed an estimated 675,000 nationwide.
According to the Centers for Disease Control and Prevention, about 10 percent of the deaths last year can be directly attributed to Covid-19, which overtook other leading causes of death — like chronic lower respiratory diseases and unintentional injuries, such as car accidents and overdose deaths — to become the third biggest killer, after heart disease and cancer.

What about the today’s flu viruses? The New York Times: The Flu Vanished During Covid. What Will Its Return Look Like?
There have been fewer influenza cases in the United States this flu season than in any on record. About 2,000 cases have been recorded since late September, according to data from the Centers for Disease Control and Prevention. In recent years, the average number of cases over the same period was about 206,000.
As measures to stop the spread of the coronavirus were implemented around the country in March 2020, influenza quickly disappeared, and it still has not returned. The latest flu season, which normally would have run until next month, essentially never happened.
After fears that a “twindemic” could batter the country, the absence of the flu was a much needed reprieve that eased the burden on an overwhelmed health care system. But the lack of exposure to the flu could also make the population more susceptible to the virus when it returns — and experts say its return is certain….
Experts are less certain about what will happen when the flu does return. In the coming months — as millions of people return to public transit, restaurants, schools and offices — influenza outbreaks could be more widespread than normal, they say, or could occur at unusual times of the year. But it’s also possible that the virus that returns is less dangerous, having not had the opportunity to evolve while it was on hiatus.
“We don’t really have a clue,” said Richard Webby, a virologist at the St. Jude Children’s Research Hospital in Memphis. “We’re in uncharted territory. We haven’t had an influenza season this low, I think as long as we’ve been measuring it. So what the potential implications are is a bit unclear.”
One more from The New York Times: Patients With Long Covid Face Lingering Worrisome Health Risks, Study Finds.
The health effects of Covid-19 not only can stretch for months but appear to increase the risk of death and chronic medical conditions, even in people who were never sick enough to be hospitalized, a large new study finds.
In the study, published Thursday in the journal Nature, researchers looked at medical records of more than 73,000 people across the United States whose coronavirus infections did not require hospitalization. Between one and six months after becoming infected, those patients had a significantly greater risk of death — 60 percent higher — than people who had not been infected with the virus.
The research, based on records of patients in the Department of Veterans Affairs health system, also found that nonhospitalized Covid survivors had a 20 percent greater chance of needing outpatient medical care over those six months than people who had not contracted the coronavirus.
The Covid survivors experienced a vast array of long-term medical problems that they had never had before — not just lung issues from the respiratory effects of the virus, but symptoms that could affect virtually any organ system or part of the body, from neurological to cardiovascular to gastrointestinal. They were also at greater risk of mental health problems, including anxiety and sleep disorders.

We’re still learning about how the coronavirus is transmitted from person to person. CNBC: MIT researchers say you’re no safer from Covid indoors at 6 feet or 60 feet in new study challenging social distancing policies.
The risk of being exposed to Covid-19 indoors is as great at 60 feet as it is at 6 feet — even when wearing a mask, according to a new study by Massachusetts Institute of Technology researchers who challenge social distancing guidelines adopted across the world.
MIT professors Martin Z. Bazant, who teaches chemical engineering and applied mathematics, and John W.M. Bush, who teaches applied mathematics, developed a method of calculating exposure risk to Covid-19 in an indoor setting that factors in a variety of issues that could affect transmission, including the amount of time spent inside, air filtration and circulation, immunization, variant strains, mask use, and even respiratory activity such as breathing, eating, speaking or singing.
Bazant and Bush question long-held Covid-19 guidelines from the Centers for Disease Control and Prevention and the World Health Organization in a peer-reviewed study published earlier this week in Proceedings of the National Academy of Science of the United States of America.
“We argue there really isn’t much of a benefit to the 6-foot rule, especially when people are wearing masks,” Bazant said in an interview. “It really has no physical basis because the air a person is breathing while wearing a mask tends to rise and comes down elsewhere in the room so you’re more exposed to the average background than you are to a person at a distance.”
The important variable the CDC and the WHO have overlooked is the amount of time spent indoors, Bazant said. The longer someone is inside with an infected person, the greater the chance of transmission, he said.
Opening windows or installing new fans to keep the air moving could also be just as effective or more effective than spending large amounts of money on a new filtration system, he said.
Bazant also says that guidelines enforcing indoor occupancy caps are flawed. He said 20 people gathered inside for 1 minute is probably fine, but not over the course of several hours, he said.
“What our analysis continues to show is that many spaces that have been shut down in fact don’t need to be. Often times the space is large enough, the ventilation is good enough, the amount of time people spend together is such that those spaces can be safely operated even at full capacity and the scientific support for reduced capacity in those spaces is really not very good,” Bazant said. “I think if you run the numbers, even right now for many types of spaces you’d find that there is not a need for occupancy restrictions.”
I mentioned the disastrous situation in India. The Guardian: India’s daily Covid death toll hits new record amid oxygen shortages.
India’s daily coronavirus death toll passed a new record Saturday as the government battled to get oxygen supplies to hospitals overwhelmed by the hundreds of thousands of new daily cases.
Queues of Covid-19 patients and their fearful relatives are building up outside hospitals in major cities across India, the new world pandemic hotspot, which has reported nearly a million new cases in three days.
Another 2,624 deaths, a new daily record, were reported in 24 hours, taking the official toll to nearly 190,000 since the pandemic started.
More than 340,000 new cases were also reported, taking India’s total to 16.5 million, second only to the United States.
But many experts are predicting the current wave will not peak for at least three weeks and that the real death and case numbers are much higher.
More from CNN: No respite in India as country sets Covid-19 infection record for third straight day.
India reported 346,786 new cases of Covid-19 on Saturday — the third day in a row the country has set a world record for infections during the coronavirus pandemic, according to government and scientific tallies.
The related death toll for the previous 24 hours hit 2,624 — also a daily record for India — for 189,544 total fatalities.
The sky-rocketing Covid-19 infections are devastating India’s communities and hospitals. Everything is in short supply — intensive care unit beds, medicine, oxygen and ventilators. Bodies are piling up in morgues and crematoriums.
Twenty critically ill patients died at a Delhi hospital Friday night after its supply of oxygen was delayed by seven hours, according to Dr. DK Baluja, medical director at the Jaipur Golden Hospital.
“That happened last night. Everything we had was exhausted. The oxygen was not supplied on time. It was supposed to come in at 5 p.m. but it came around midnight. People who were critically ill needed oxygen,” said Baluja.
The hospital is currently scrambling to arrange more oxygen but has not received a fresh supply all Saturday morning. “We have only 15-20 minutes of oxygen left now. It may take hours to get another tanker,” Baluja told CNN.
Delhi hospitals have been facing a severe oxygen shortage as the number of Covid-19 cases have soared in the national capital in the past two weeks….
Delhi recorded 24,331 new cases Friday, including 348 deaths, according to the Covid-19 health bulletin issued by the Delhi government.
Countrywide, India has now recorded more than 16.6 million cases since the start of the pandemic, a CNN tally of figures from the Indian Ministry of Health reveals.
In contrast, Vietnam successfully limited the spread of the virus. The Verge: Vietnam defied the experts and sealed its border to keep Covid-19 out. It worked.
As the pandemic took hold last year, travel restrictions quickly proliferated — they were the second-most-common policy governments adopted to combat Covid-19. According to one review, never in recorded history has global travel been curbed in “such an extreme manner”: a reduction of approximately 65 percent in the first half of 2020. More than a year later, as countries experiment with vaccine passports, travel bubbles, and a new round of measures to keep virus variants at bay, a maze of confusing, ever-changing restrictions remains firmly in place.
But few countries have gone as far as Vietnam, a one-party communist state with a GDP per capita of $2,700. The Haiphong checkpoints timed for Tet were the equivalent of closing off Los Angeles to Americans ahead of Thanksgiving — within a country that was already nearly hermetically sealed. Last March, the government canceled all inbound commercial flights for months on end, making it almost impossible to fly in, even for Vietnamese residents.
Today, flights are limited to select groups, like businesspeople or experts, from a few low-risk countries. Everybody who enters needs special government permission and must complete up to 21 days of state-monitored quarantine with PCR tests. (Positive cases are immediately isolated in hospitals, regardless of disease severity.)
This strict approach to travel, global health experts say, is directly connected to Vietnam’s seeming defeat of Covid-19. Thirty-five people have reportedly died in total, and a little more than 2,700 have been infected with the virus during three small waves that have all been quickly quashed. Even on the worst days of the pandemic, the country of 97 million has never recorded more than 110 new cases — a tiny fraction of the 68,000 daily case high in the United Kingdom, which has a population one-third smaller than Vietnam, or the record 300,000-plus cases per day only the US and India managed to tally.
Finally, The Daily Beast addresses the crazy anti-vaxxer situation: The Anti-Vaxxer Hunt for Dead People Is Getting Even Weirder.
Starting in mid-January, several social media channels and websites emerged as hubs for stories, generated by admins and users pulling together snippets from across the internet and crafting them into cohesive narratives and brief posts, linking reported deaths to COVID vaccinations. Several of these platforms have grown notably, and become more formalized, in recent weeks. Unsurprisingly, given the robust safety profile of the vaccines in use in the United States, they rarely detail how a vaccination supposedly caused a given death.
