It went well A year after the first known case of coronavirus was published in China, the threat of the virus exceeded normal life, and phrases such as “social distance” and “contact tracing” entered our collective vocabulary. From unemployment statistics to drug trials, new information about the epidemic is constantly emerging, and dozens of theories about the disease are updated or rejected any day. As the disease epidemic progresses over the summer, a large number of questions are raised about everything from the spread of the Delta variant to what it will look like to vaccinate children. We’ve put together a guide to what you need to know about this epidemic – how to keep your kids entertained or how this outbreak is affecting the economy. We will update it regularly to help you keep track of all aspects of this evolving situation.

Basic background

What is coronavirus, and when did it become an epidemic

The 2019 coronavirus is one of the hundreds we know of, and one in seven that infects humans. The virus affects the lungs and can cause fever and sometimes gastrointestinal problems. The World Health Organization declared the coronavirus situation a global crisis in January 2020 and an epidemic in mid-March. The epidemic will probably end, but some experts now say the virus becomes a local epidemic and sticks to it in a less lethal form. Although we do not know exactly when and how the virus jumped into humans from bats, efforts are still being made to find it.

Features of Covid 19

The most common symptoms of Covid-19 are dry cough, fever and shortness of breath. Others include diarrhea and loss of smell or taste. Some people develop severe blood clots. The disease is enterprising – mild for some and fatal for others. Scientists can’t say for sure why, but women are less likely than men. We know that older people, especially those with internal health problems, are at higher risk. Children are better off than adults, but the disease can be serious for children, toddlers and children with other conditions. On the long road to recovery, people have experienced “brain fog”, heart problems and other long-distance problems.

Questions of social distance and safety

The social distance is to stay away from others for a long time to slow down the spread of the virus. When you have to stay close to others, such as in a grocery store, when someone is delivering food or going for a walk, disease control and prevention centers recommend staying 6 feet away. To enforce this, many states have enforced orders in shelters throughout epidemic sites. As places have begun to reopen – and plans to reopen have turned – everyone has questions about what is safe. You should still avoid traveling, especially by plane, if you have not been vaccinated. Scientists are still trying to figure out how the virus is spread through the air, especially in urban areas. To navigate life amid epidemics, some public health experts have even created color-coded guides. But there is no foolproof way to calculate the risk. The only way to avoid spreading Covid-19 is to follow as many public health guidelines as possible.

How long do coronaviruses last on the surface (and how to disinfect them)

We now know that you are much more likely to get coronavirus from shared air than from shared surfaces. That said, it is not a bad idea to regularly clean and disinfect high-touch items and surfaces such as doorcombs, remote controls and counters. Of course, one of the most important things you can do is wash your hands! You need soap or disinfectant. You can also make your own sanitizer at home.

Wearing a mask

The CDC recommends wearing a mask in public places where it is difficult to maintain social distance measures, especially if you have not been vaccinated. They must be, and here are some of our favorites. When you stock up, remember that not all masks are created equal. You should place a disposable surgical mask under the fabric face covering. Here are our tips for making cloth an external mask – all you need is a T-shirt and two rubber bands.

Types of new viruses

All viruses change over time, as they spread from person to person. The novel coronavirus is no exception, but recently some new strains have emerged that seem more contagious, especially the delta variant, now in the U.S. Strong stress in. The good news is that, so far, the vaccines we have are still largely effective in protecting against these new types. And not all types cause alarms. As scientists promote the genetic sequence to detect these and other mutations more effectively and the vaccination drive continues, the advent of this strain means that following social distance guidelines is more important than ever.

Testing, treatment and vaccination

Latest test updates

At some point, especially during the holidays, many people have acted on the assumption that a negative test means it is safe to associate with others. But as we know from the last fall superspreader event at the White House, we need to do more than just test to prevent the virus from spreading. And even the test results themselves are not responsible for the noise of the disease.

Covid-19 treatment

At the moment, there is no definitive cure for Covid-19. Some researchers have examined chloroquine, a drug prescribed by President Trump for malaria, but there is no evidence that it is a viable treatment. Others investigated the use of anti-influenza drugs and Crisprip to treat the disease. Antiviral rimadasivir can be helpful even though it is expensive. Hopefully the research will find older drugs more effective for treating Covid-19, thereby simplifying the drug detection process. All, however, Covid-19 drug research has proven to be very messy.

For now, common medications may be helpful for those struggling with Covid-19. The blood of healed patients also showed some promise. Although we don’t know exactly how effective it is, and getting it to those in need is a challenge, the Food and Drug Administration has fixed its emergency use. Researchers are also examining the antibodies of rare people who think there is a strong defense instead. And AI is being used to speed up everything from diagnosis to drug discovery. Mostly, it’s important to remember that finding a cure takes time, and there are a lot of questionable theories circulating circline. Whatever you do, please do not try to bleach.

Vaccine development

In December, the U.S. approved its first two Covid-19 vaccines, including Pfizer-Bioentech and Moderna. This is clearly a fast-paced scientific achievement, so more so when you consider that both are the first valid vaccines used to identify and fight mRNA (SRS-CoV-2) to train the immune system. Although very few severe adverse reactions have been reported, many people experience side effects, usually within a day or two of fever-like symptoms. The fact that these vaccines were authorized for emergency use may have little effect on the fate of his ongoing trials. And now that they have been approved for use in adults, teenagers and twins, trials for children are underway. In late February, the FDA approved a third vaccine for Johnson and Johnson. Although he stopped using the vaccine for a short time in April due to concerns about rare blood clots, the shot is now reusable, as its benefits outweigh the risks.

Meanwhile, trials for a number of other vaccines are ongoing. This is a good thing: we will need more vaccines to inoculate everyone, and it is always possible that trial vaccines may now prove to be better than the ones we have. Now that more and more variants are emerging, research has also begun on how to update existing shots, and to understand the effects of these vaccines on different individuals over time.

Vaccine rollout

When it comes to rollouts, two big questions have arisen: in what order should people get vaccinated, and how can they get vaccinated as effectively as possible? Currently the U.S. Two of the three shots approved for use in, from Pfizer-Bioentech and Modern, require two doses and must be stored at very cold temperatures, two factors that have a complex distribution. There is also the issue of supply. At times, many Americans have difficulty deciding when to qualify and schedule an appointment. Some experts have started the idea of ​​setting up mass vaccination clinics, but even that will not fully address the issues of equity and access. Distribution plans adapt to people with disproportionate time and access to the Internet, often to the detriment of the needy. On top of all this, it is important to build trust among vaccinators, especially in communities that have historically been victims of medical racism. One solution that seems to work: vaccine lotteries. For the epidemic to truly end, vaccinated people also need to be vigilant and everyone around the world will need access to the vaccine.

What to do if you or a relative is sick

Then whether you raise a family or live alone, it is best to be alone at home and keep your space clean. And whether you are sick or healthy, it is important to take care of your mind and body.

Epidemiology and tracking

How Kovid-19 is spread

We know that the virus is passed from one person to another when someone coughs or sneezes. Jeremy dust can also be a vector of disease. The outbreak spreads quickly in the beginning but slows down over time, especially if additional measures are taken to derail the turn. And some researchers are exploring the possibility that the virus could return to the season like the common cold. There was no flu season during the epidemic, which means our measures to stop the spread, and that too. [future flu seasons] (https://www.wired.com/story/covid-lockdowns-prevented-other-infections-is-that-good/) may be worse than our use.

How other countries have handled it

Some countries chose to have a strict lockdown. Others, such as South Korea, Singapore and Taiwan, initially squared the turn due to extensive testing and tracing efforts. U.S. And travelers from Europe later encouraged the increase in cases, U.S. There is still a lot to learn. As far as information is transmitted, censorship and misinformation have proven to be issues worldwide.

How coronavirus is tracked

In order to create useful models and fully understand coronavirus, we need to know how it is spread. Many countries are either using smartphone apps and location data to detect the spread of the virus or are working to put in place a contact tracing system. To reduce concerns that this contact tracing would be a breach of privacy, companies such as Apple Pal and Google collaborated on a Bluetooth-based system that would track coronaviruses and notify people who were exposed without conducting a survey.

Beyond smartphones, some countries and workplaces have begun using thermal cameras to detect potential fevers, and monitoring of wearable devices and sewers can also be helpful. In some places, the QR code has its moment. And some city and state officials are skeptical about digital tracing, instead employing thousands of people for tracing. At the federal level, there has been talk of creating a national epidemic forecasting agency to study the covid and advance future epidemics.
