Drunk driving is like a wolf and drug driving is like a tiger. The World Health Organization points out seven types of drugs that may affect driving safety after taking them. All new and old drivers should pay special attention to "side effects and Taboos" in the instructions before taking drugs.
The recent wave of COVID-19 has spread in many provinces and cities, and the epidemic prevention and control is facing a grim situation. The rival of the outbreak is COVID-19, but it has changed to a new look, called COVID-19 Delta.
What is the new crown variant virus delta strain?The delta strain of the new crown variant virus has spread to 92 countries. So, what are the characteristics of delta strain? What is the current communication situation? How to prevent?
More dangerous! Delta has not been solved, the new mutant virus has spread to Japan, and the who has issued a warning.After the discovery and rapid expansion of COVID-19, people all over the world fought to fight the virus. In the end, many countries have returned to normal.
Emerge in an endless stream of mutation COVID-19, from Alfa, beta, gamma to del and Miao virus strains, constantly challenge the epidemic prevention and control in various countries. Among them, delta strain has become the main variant strain prevalent in most parts of the world, and it is more infectious.
Here is a guide to novel versions of the COVID-causing virus—and genetic changes that can make them more contagious and evasive in the body.When the coronavirus SARS-CoV-2 burst upon the world last winter, scientists knew it was bad. But they also thought it was stable. Coronaviruses do not mutate as readily as the viruses that cause the flu, hepatitis or AIDS, for instance—thanks in part to a molecular “proofreading” system that SARS-CoV-2 and its kin use to prevent damaging genetic errors when replicating.
The SARS-CoV-2 virus has mutated over time, resulting in genetic variation in the population of circulating viral strains over the course of the COVID-19 pandemic. Molecular, antigen, and serology tests are affected by viral mutations differently due to the inherent design differences of each test.

What do we know about other COVID variants?The delta variant is just the latest one to cause concern in the U.S. as it spreads across the globe. Earlier this year, more infectious variants from the U.K., South Africa and Brazil made headlines as they became more dominant in different parts of the world.
Once again, some of the latest headlines about the ongoing COVID-19 pandemic are alarming: Another variant of the virus is now on the rise in the United States.“Although this is concerning, it’s not surprising — we’ve been watching for this and more or less expecting it,” explains microbiologist and pathologist Daniel Rhoads, MD.
What is ozone therapy? According to the retelling of friends and the information on the Internet, the so-called ozone therapy may refer to "washing blood" with ozone, extracting the blood from the human body, injecting ozone into the machine, and then injecting the blood back into the body.
No wonder americans refused to vaccinate. Japan found Pfizer hiding a secret and waited for the White House to reply: in the tense global vaccine supply, vaccines are very valuable to many countries. However, in this critical period, the quality of some overseas vaccines is difficult to guarantee, and even foreign bodies are mixed in the vaccine.
4.5 million people died in the "catastrophe", the new crown "poison king" spread all over the world, and the vaccine failed?Novel coronavirus pneumonia is still in the "whirlpool" of the world. The world epidemic situation is still grim. This also makes our country at risk all the time. According to statistics, over 200 million cases of new crown pneumonia have been diagnosed worldwide, and about 4500000 cases have been killed.
