Covid 19


The rules for Covid-19 and its variants change as there are many unknown variables including the vaccine, short and long term effects, and more. An end-time pandemic continues until the end - as anger, frustration, speculation, anxiety and fear continue. Covid in any form seems to have consciousness and an agenda of its own. It behaves like artificial intelligence.




Coronavirus disease 2019 (COVID-19) is a contagious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The first known case was identified in Wuhan, China, in December 2019. The disease has since spread worldwide, leading to an ongoing pandemic.

Symptoms of COVID-19 are variable, but often include fever, cough, headache, fatigue, breathing difficulties, loss of smell, and loss of taste. Symptoms may begin one to fourteen days after exposure to the virus. At least a third of people who are infected do not develop noticeable symptoms.

Of those people who develop symptoms noticeable enough to be classed as patients, most (81%) develop mild to moderate symptoms (up to mild pneumonia), while 14% develop severe symptoms (dyspnea, hypoxia, or more than 50% lung involvement on imaging), and 5% suffer critical symptoms (respiratory failure, shock, or multiorgan dysfunction).

Older people are at a higher risk of developing severe symptoms. Some people continue to experience a range of effects (long COVID) for months after recovery, and damage to organs has been observed. Multi-year studies are underway to further investigate the long-term effects of the disease.

COVID-19 transmits when people breathe in air contaminated by droplets and small airborne particles containing the virus. The risk of breathing these in is highest when people are in close proximity, but they can be inhaled over longer distances, particularly indoors. Transmission can also occur if splashed or sprayed with contaminated fluids in the eyes, nose or mouth, and, rarely, via contaminated surfaces. People remain contagious for up to 20 days, and can spread the virus even if they do not develop symptoms.

Several testing methods have been developed to diagnose the disease. The standard diagnostic method is by detection of the virus's nucleic acid by real-time reverse transcription polymerase chain reaction (rRT-PCR), transcription-mediated amplification (TMA), or by reverse transcription loop-mediated isothermal amplification (RT-LAMP) from a nasopharyngeal swab.

Several COVID-19 vaccines have been approved and distributed in various countries, which have initiated mass vaccination campaigns. Other preventive measures include physical or social distancing, quarantining, ventilation of indoor spaces, covering coughs and sneezes, hand washing, and keeping unwashed hands away from the face.

The use of face masks or coverings has been recommended in public settings to minimize the risk of transmissions. While work is underway to develop drugs that inhibit the virus, the primary treatment is symptomatic. Management involves the treatment of symptoms, supportive care, isolation, and experimental measures. Read more




Pfizer COVID-19 third dose vaccine protection against hospitalization from omicron wanes after 3 months: study   Medical Express - April 22, 2022




As Virus Data Mounts, the J.&J. Vaccine Holds Its Own against Pfizer and Moderna   NY Times - March 15, 2022
Roughly 17 million Americans received the Johnson & Johnson Covid vaccine, only to be told later that it was the least protective of the options available in the United States. But new data suggest that the vaccine is now preventing infections, hospitalizations and deaths at least as well as the Pfizer-BioNTech and Moderna vaccines. Accumulating data nonetheless offer considerable reassurance to recipients of the vaccine and, if confirmed, have broad implications for its deployment in parts of the world.




Two years into the pandemic, which of our newly formed habits are here to stay?   PhysOrg - March 10, 2022
We've got here by learning a lot of "new" health behavior, like wearing masks and sanitizing our hands. Many of us have also developed a variety of social habits to reduce the virus's spread - such as working from home, shopping online, traveling locally and socializing less.




Even 'Mild' COVID Is Linked to Significant Brain Changes, Large Study Reveals   Science Alert - March 10, 2022
One of the largest COVID-19 brain imaging studies to date has shed some unsettling light on the disease's impact on our brains. Even in those with a mild or moderate case, a SARS-CoV-2 infection was associated with "significant" neurological changes and loss of gray matter.




Scientists Built a Coronavirus From Scratch, Then Saw It Trying to Hide   Science Alert - February 24, 2022
If you want to truly understand what makes a machine tick, you need to tinker. Swap gears, lock a lever, loosen a spring, and watch how it goes. When the machine is a deadly virus, you can't afford to be so cavalier with its molecular clockwork. But researchers are getting around this problem by making minimalist versions of dangerous microbes that barely teeter on the edge of functionality.
