Covid-19: What are the risks of catching the virus multiple times? – New Scientist

Posted: June 29, 2022 at 12:54 am

A study suggests people who catch covid-19 at least twice have double the risk of dying from any cause and are three times as likely to be hospitalised in the next six months, compared with people who test positive just once

You have been vaccinated and recently had covid-19, so you dont have to worry about catching it again, right? Wrong. A large study suggests that every time a person is reinfected, they have additional health risks, both during their immediate illness and in the months afterwards.

Every reinfection is like rolling the dice again, says Ziyad Al-Aly at VA St. Louis Health Care System in Missouri. A second infection is still bad for you.

COVID-19 mutations spreading in Austin-Travis County, reinfections may be more severe – KXAN.com

Posted: at 12:54 am

AUSTIN (KXAN) COVID-19 metrics, including hospitalizations, are starting to trend upward again in Austin-Travis County. The local health authority attributed the uptick to the BA.4 and BA.5 offshoots of the omicron variant in a Travis County commissioners court meeting Tuesday.

Those mutations are starting to show up in both wastewater and in variant surveillance locally, according to the health authoritys report. They could be more severe than previous mutations.

With each mutation, it [COVID-19} is becoming adept at evading our immune systems defenses and that is why these two particular variants are starting to become more predominant. Dr. Desmar Walkes said.

As of Monday, Walkes reported there are nearly 100 people in area hospitals with COVID-19, 18 of those people are in intensive care units. Roughly half of the people hospitalized are there primarily for COVID-19.

More people that are requiring oxygen and starting to require life support, Walkes said, noting that research done on BA.4 and BA.5 shows the mutations may impact lung tissue more than previous mutations. She also said for people who had COVID-19 during the winter omicron surge, reinfection with BA.4 and BA.5 could be more severe.

With each subsequent infection, there is an increase in the impact, Walkes said. Reinfection is not benign.

Travis County is presently in the medium level of risk based on the Centers for Disease Control and Preventions risk tracker. Under that level, APH is recommending people at high risk, and people who live with someone who is high risk, wear a mask in public.

For people who had COVID-19 during the original omicron surge, immunity is likely waning. The UT COVID-19 Modeling Consortium talked about that when case numbers started to trend upwards earlier this month.

Its been four or five months after the first omicron wave, where we had so many infections, and so we expect that there will be many people losing immunity at a rapid speed, said Anass Bouchnita, a postdoctoral fellow with the consortium.

People who previously had COVID-19 may also be at greater risk of getting seriously sick if they do catch COVID-19 again, Walkes explained. Staying up-to-date on vaccinations are still the best protection against the virus, she said.

We are still seeing good coverage and protection that is offered to people who are vaccinated from severe illness, hospitalization and death. We are still recommending vaccinations and boosters for those who are eligible, Walkes said.

‘Better vaccines’ needed to cover COVID variants, infectious disease experts say – KSTP

Posted: at 12:53 am

Dr. Gregory Poland, an infectious disease physician at Mayo Clinic in Rochester, told 5 EYEWITNESS NEWS the original vaccines against the COVID-19 virus did a terrific job keeping people out of the hospital and preventing death, but he said moving forward better vaccines need to be developed.

The current vaccines offer only mild benefit, in terms of infection, against those new variants, said Poland. So, the idea is, and both Moderna and Pfizer both plan no doing this, to devise vaccines that cover the Omicron variant.

Poland told 5 EYEWITNESS NEWS the goal is to possibly have an updated COVID vaccine by early fall by using part of the original vaccine and the vaccine that was used during the Omicron surge.

But, Poland said the ultimate goal is to develop a so-called Pan-Corona Vaccine which would offer better protection against all of the variants that have emerged with the virus.

The idea that we, and others are working on, is a Pan-Corona virus vaccine. Or, if you will, a universal Corona virus vaccine, said Poland. Thats still a ways off, but thats the goal.

Dr. Peter Bornstein, with St. Paul Infectious Disease Associates, told 5 EYEWITNESS NEWS he agrees with the push by the Food and Drug Administration to come up with a more effective vaccine.

We definitely need better vaccines. How much the virus itself will keep mutating, and have immunological escape from the vaccines, we just dont know yet, said Bornstein.

The FDA met Tuesday to discuss the future of new COVID vaccines, but did not yet offer any recommendations.

The 5 Most Dangerous Spots You Can Catch Coronavirus Eat This Not That – Eat This, Not That

Posted: at 12:53 am

The Omicron BA.2.12.1 subvariant is now the dominant COVID-19 variant in the US, responsible for 58% of recorded new coronavirus cases in the last week alone. "I'm in Connecticut, and it's like 80% of all sequences that we see right now," says Anne Hahn, PhD., postdoctoral researcher at the Yale School of Public Health. Here are the five most dangerous spots to catch COVID-19, according to experts. Read on to find out moreand to ensure your health and the health of others, don't miss Already Had COVID? These Symptoms May "Never Go Away".

Indoor gatherings such as weddings and parties are still dangerous, warns the World Health Organization. "In the context of the COVID-19 pandemic, there is no 'zero risk' when it comes to any kind of gathering especially events that bring groups of people together," says the WHO. "Regardless of the size of the event, you are at risk from COVID-19 whenever you get together with people. The virus that causes COVID-19 spreads easily indoors, especially in poorly ventilated settings."

Planning a family cruise this summer? The CDC has lifted its warning on cruise ship travel, but virus experts are still recommending caution. "This means to prepare for the cruise, all four of you should be fully vaccinated and boosted," says Jessica Justman, infectious diseases specialist and epidemiologist at the Columbia University Irving Medical Center, who recommends travelers make sure their ship has opted into the CDC's Covid-19 Program for Cruise Ships. "I suggest completing all booster doses a few weeks, and at least one week, before the trip starts. I would also be interested in how many inpatient beds and medical personnel are on the cruise and compare that to the number of passengers. One might confirm that the cruise follows guidelines such as the cruise ship health care guidelines from the American College of Emergency Physicians."

Buffets are risky due to close contact with both customers and staff. "While common utensils theoretically could lead to transmission of COVID from hand to spoon to hand, we actually don't have any good examples in clusters of COVID illnesses that surfaces really matter as much as people all standing close to each other does," says Benjamin Chapman, Ph.D., professor and food safety specialist in the department of Agricultural and Human Sciences at North Carolina State University. "Managing social distancing and line-ups is really the hardest part. Or in situations where staff will serve patrons from a buffet, the staff and patron interaction is the riskiest part."6254a4d1642c605c54bf1cab17d50f1e

Indoor gyms are still highly problematic in terms of catching the virus, experts warn. "If you're not willing to get COVID don't go," says Dr. Michael Klompas, a hospital epidemiologist and infectious disease physician at Brigham and Women's Hospital. "At a time like now, when there's a lot of COVID around, it is a high risk proposition."

Social distancing is practically impossible in airports, with people standing next to each other in check in and security lines and sitting close together on planes. "Avoid common-touch surfaces, hand hygiene wherever possible, masks, distancing, controlled-boarding procedures, try to avoid face-to-face contact with other customers, try to avoid being unmasked in flight, for meal and drink services, apart from when really necessary," says David Powell, physician and medical adviser to the International Air Transport Association. "The greatest protection you can give yourself is to be vaccinated and boosted."

Follow the public health fundamentals and help end this pandemic, no matter where you liveget vaccinated or boosted ASAP; if you live in an area with low vaccination rates, wear an N95 face mask, don't travel, social distance, avoid large crowds, don't go indoors with people you're not sheltering with (especially in bars), practice good hand hygiene, and to protect your life and the lives of others, don't visit any of these 35 Places You're Most Likely to Catch COVID.

Coronavirus cases on the rise once again – KAMR – MyHighPlains.com

Posted: at 12:53 am

AMARILLO, Texas (KAMR/KCIT) COVID-19 cases are rising across the Amarillo area, Texas, and the nation.

The city of Amarillo is seeing more than 800 more active cases than we had this time last month.

Dr. Rodney Young, Regional Chair of Family & Community Medicine at the Texas Tech University Health Sciences Center said what is causing the rise in new cases is a new subvariant.

It started with the Omicron, then with the BA.2 and now there is a subvariant of BA.2, said Dr. Young.

He said cases are likely to continue to rise as July 4th draws near and families gather.

When you have occasions to gather, that is the way it spreads very easily person to person, said Dr. Young.

Dr. Young added as cases do continue to rise, an upside is that they have not seen a rise in hospitalization the way they did in the earlier stages of the pandemic.

He said patients with the subvariant are not presenting with severe COVID-19 symptoms, some are presenting with a little cough, runny nose, and watery eyes.

A number of the cases that we are diagnosing now that werent COVID a few weeks ago, tend to be folks they are feeling like they are having flares in allergy symptoms or cold type symptoms, said Dr. Young.

Dr. Young said that those who are vaccinated and who get subvariant COVID illnesses are less likely to get less severe forms of the illness or experience long covid.

Dr. Young added the virus is here to stay and it will always be a part of the disease landscape to some extent and added what the medical community hopes to happen is that it moves from a pandemic to an endemic.

Some years or some times are worse than others, but hopefully there is enough immunity around and enough measures that we can take to help mitigate the spread within a community, said Dr. Young.

Dr. Young said he doesnt have an exact answer to when that could happen, but he said its possible we could be seeing the early stages of that now.

Dr. Young reiterates that the best way to keep yourself protected from these rising cases is social distancing, good hygiene practices, and getting boosted if you havent done so already.

Gravity Diagnostics closes COVID-19 testing sites as fewer in the Tri-State get tested – WCPO 9 Cincinnati

Posted: at 12:53 am

COVINGTON, Ky.Just months ago, the parking lot at Gravity Diagnostics in Covington was filled as people waited hours to get tested for COVID-19. Now, the site is shutting down as fewer people look for in-person tests.

Kelly Theurer stopped by the site one day before closing to get tested and say goodbye.

"I'm terribly sad," Theurer said. "I've been coming here since they set up shop in this parking lot. I travel a lot for work ... and it's literally the only place in the Tri-State where I can come, drive-thru, get a quick test and get the results back really fast."

Jeff Wellens, director of field services for Gravity Diagnostics, said they are closing because their partnership with the city is ending and the number of people getting tested continues to decrease.

"Last January, we were hitting about 2,000 a day and that was sustained for a good number of weeks after the holiday and at the present time we are just under about 10% of that now about 200 tests a day between the site here and the Florence Mall," Wellens said.

Ashley Auciello with the Health Collaborative said the overall number of tests in the Tri-State has dropped. Dr. Stephen Feagins, medical director for Hamilton County Public Health, said that doesn't mean the positivity rate is lower than before.

"Right now, it feels like things are kind of normal, but yet the positive rate for Southwest Ohio was like 1.6% this week last year, and it's almost 12% this week this year," Feagins said.

Feagins said that number is partly because testing is less frequent, but noted COVID has not become endemic.

"Endemic really isn't that term because endemic really means that you can predict when the flu season is going to start, you know kinda what's it going to be like, you know when you need to vaccinate for the flu each year," Feagins said. "You're not sure about that with COVID yet."

Theurer said she isn't sure where she'll go to get tested in the future. Aucielle recommended visiting TestAndProtectCincy.com to find COVID testing locations.

We’re in Awe of this Absolutely Deranged "Nuclear-Powered Sky Hotel" – Futurism

Posted: at 12:52 am

"I bet I still end up next to someone else's screaming three year old for the entire trip."Howl's Nuclear Castle

It's definitely not a bird, but it is sort of a plane. Specifically, it's a non-existent but admittedly very cool concept called theSky Cruise, a fantastical nuclear-powered sky hotel.

The impressively-detailed video rendering visualizes a hulking airborne vessel, allegedly designed to house over 5,000 guests in nearly nonstop flight. Alongside magnificent views of nature including a close-up look at the Northern lights there are seemingly endless things to do: fancy restaurants, a massive shopping mall, gyms, theaters, pools, wellness and medical services, event spaces, and more. The narrator even points out that getting married above the clouds would be a pretty awesome way to say "I do."

But, as one YouTube commenter pointed out, there seems to be one very important amenity missing.

"I'd still want an old-fashioned arcade where I can turn my tickets in for cheap-azz prizes," they wrote. Honestly, fair.

The conceptual skycraft boasts 20 electric engines, powered solely by a "small nuclear reactor" that "uses highly-controlled fusion reaction," And because it wouldn't need to be refueled, it would rarely need to land. Guests would fly to and from the sky high hotel on commercial or private jetliners, and all repairs would be done in-air.

Many commenters, however, were quick to call out design flaws not the least being that practical nuclear fusion doesn't actually exist yet. And even if it did, there would be other immense engineering challenges to surmount.

"If physics and aerodynamics didn't exist, then this vessel might actually be able to take off," remarked another YouTuber. Harsh!

But the biggest caveat of all? The narrator claims that the design "combines the features of a commercial plane, while offering the epitome of luxury." Seeing as how commercial plane and luxury do not belong in the same sentence, that feels like a major plothole.

As another commenter so elegantly put it: "I bet I still end up next to someone else's screaming three year old for the entire trip."

Scientists Say the Sun Is Acting Up and Causing Satellites to Fall Back to Earth – Futurism

Posted: at 12:52 am

Space weather is weird.Down, Down Down

Most folks probably don't think of satellites as capable of sinking, but according to the European Space Agency they can and do.

Space news site Space.com reported Thursday that ESA scientists had to raise the Swarm constellation satellites, which measure Earth's magnetic field, because they were sinking in chaotic space weather.

"In the last five, six years, the satellites were sinking about two and a half kilometers [1.5 miles] a year," Swarm mission managerAnja Stromme, ESA's told Space.com. "But since December last year, they have been virtually diving. The sink rate between December and April has been 20 kilometers [12 miles] per year."

Although satellites always face a downward drag while in orbit, space weather has been making the sink worse, the ESA said. That's why the International Space Station makes frequent maneuvers to keep itself in orbit and out of the worst of the drag.

Space.com says that since last fall, the Sun has been acting pretty weird in general.

A growing sun spot has doubled in size and is pointed directly at the Earth, although scientists say we shouldn't be concerned (but then, how could you not be?) That phenomenon may not be connected with sinking satellites, but it does highlight how conditions in space are ever-changing.

We'll keep our eyes out for more space weather updates, because it sure does seem like there's at least some stormy weather going on up there.

NASA Spots Location Where Derelict Rocket Smashed Into the Moon – Futurism

One more crater!Moonstruck

We may finally have found closure for the saga of the derelict rocket believed to have crashed into the Moon earlier this year. Scientists have discovered a newly-formed double crater on the far side of our natural satellite, according to a NASA press release, where they believethe defunct spacecraft smashed down.

Using imagery captured by NASA's Lunar Reconnaissance Orbiter (LRO), astronomers were able to deduce that the mystery space debris spotted on collision course for the Moon back in February crash-landed near the Hertzsprung Crater in early March.

The scientific community also seems very pleased that the debris made lunar contact pretty much right where they thought it would.

"Newton wins again," joked Jonathan McDowell, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics, in an email to Gizmodo.

The ramshackle rocket has faced its fair share of controversy.

When the hunk of junk was first caught speeding towards the lunar surface, it was believed to a SpaceX second stage Falcon 9 craft an allegation that CEO Elon Musk took a lot of heat for.

But further observation revealed otherwise, and now experts believe that the unfortunate debris was actually a Chinese Chang'e 5-T1 booster, left over from the nation's 2014 mission to the Moon.

China, however, denies any responsibility, insisting that the Chang'e shuttle in question was eviscerated when re-entering Earth's atmosphere.

The fact that the Definitely Not Chinese rocket created a double crater raises its own questions. As Gizmodo points out, it's a strange mark for any spacecraft to make; NASA speculates that the "unexpected" impact shape implies that the space trash must have had "large masses at each end," which doesn't necessarily check out for a Chang'e. So, maybe we don't have closure after all?

In any case, it's a bummer that humankind has officially hurled even more garbage at our lunar friend in the sky. This is why we can't have nice things.

Weirdly, It Appears the Flu Vaccine May Protect Against Alzheimer’s – Futurism

Posted: at 12:52 am

In a surprise finding, researchers have found that getting at least one flu shot makes it 40 percent less likely for people over the age of 65 to be diagnosed with Alzheimer's disease, up to four years later.

While it's still far too early to determine if there are any direct causal links between the common vaccine and neurological health outcomes like Alzheimer's in other words, we don't know if it's the flu vaccine itself or something else responsible for the results the research is certainly an eyebrow-raising new development that could,potentially, point in the direction of easily accessible treatments.

In a peer-reviewed study in the Journal of Alzheimer's Disease, researchers at UTHealth Houston compared the incidence rate of the disease in patients with and without at least one flu vaccination in a nationwide sample of US adults aged 65 and up, which included 935,887 vaccinated and 935,887 non-vaccinated individuals.

The results are modest but intriguing, especially considering how much time and effort is being invested in slowing down and reversing the disease. Around 5.1 percent of those with prior flu vaccinations developed Alzheimer's, compared to 8.5 percent of unvaccinated patients who were later diagnosed with the disease.

"We found that flu vaccination in older adults reduces the risk of developing Alzheimers disease for several years," said first author Avram Bukhbinder, recent UTHealth Houston graduate, in a statement. "The strength of this protective effect increased with the number of years that a person received an annual flu vaccine in other words, the rate of developing Alzheimers was lowest among those who consistently received the flu vaccine every year."

"Future research should assess whether flu vaccination is also associated with the rate of symptom progression in patients who already have Alzheimers dementia," Bukhbinder added.

Most notably, the researchers don't know the underlying mechanisms that could explain the schism between vaccinated and unvaccinated individuals that is, if there are any in the first place.

"Since there is evidence that several vaccines may protect from Alzheimer's disease, we are thinking that it isn't a specific effect of the flu vaccine," said senior author and UTHealth MD Paul Schulz in the statement. "Instead, we believe that the immune system is complex, and some alterations, such as pneumonia, may activate it in a way that makes Alzheimer's disease worse."

There may be other reasons as well.

"But other things that activate the immune system may do so in a different way one that protects from Alzheimer's disease," he added.

In short, it's an interesting blip in the data that deserves plenty of future research.

"Clearly, we have more to learn about how the immune system worsens or improves outcomes in this disease," Schulz argued.
