The Corona virus continues to shake the world at an astonishing clip, propelling an alarming succession of epidemic epidemics in 2022: 300 million known cases worldwide by early January, 400 million by early February and Tuesday , Half a billion
There are almost certainly more infections among the global population of 7.9 billion, many of which are unknown or unreported, and the reporting gap can only expand as some countries, including the United States, conduct official investigations. From the
“It’s dangerous,” Ali Mukadad, an epidemiologist at the University of Washington, and formerly of the Centers for Disease Control and Prevention, said in a recent interview. “If you don’t test, you don’t know what kind you have.”
Regional officials with the World Health Organization recently called on African countries to accelerate testing and contact detection, and urged some US countries to support vaccination and test promotion efforts as cases in Europe continue to rise. (The United Kingdom, for example, abolishes free testing.) A WHO analysis also recently estimated that 65% of Africans were infected with the Coron virus by September 2021, almost 100 times the number of confirmed cases on the continent.
The number of new cases reported every day in the world has been decreasing for some time; According to the Center for System Science and Engineering at Johns Hopkins University, there are an average of 1.1 million cases a day over the past week. That’s about 32% less than two weeks ago.
But during the epidemic, countries with limited public health resources can detect and confirm a small fraction of cases in their population. And more recent statistics may increase the speed of test results on many homes that have never been officially reported. Most people with infections will never get tested, because they have no symptoms, or have no test, or because they want to avoid positive test results, or for other reasons. They do not choose.
Corona virus deaths are also decreasing. The world averaged 3,800,23 reports per day over the last week, 23% less than two weeks ago.
Still, the WHO’s director general, Dr. Tedros Adahanom Gibresses, recently said that the world is in a difficult phase of pandemic, and many health experts agree.
Expert warnings have not stopped many nations from fully abolishing their pandemic caution in two months, when the number of global cases increased to more than 400 million. In the United States, the Centers for Disease Control and Prevention issued new guidelines at the end of February, stating that most Americans could stop wearing masks, and no longer needed to maintain social distance or avoid home-grown places. جي.
“What is happening globally and in the United States,” said Dr. Mokad, “is what people basically give. They just want to get back to normal life.
This desire is threatened by the rapid spread of the Omicron subvariant known as BA.2, the most transmitted version of the virus, so far. BA.2 now accounts for the vast majority of new cases in the United States and around the world; It spreads much faster than BA.1, which helped fuel growth in the winter.
The peak of the recent surge may have passed in some parts of Europe, but Hong Kong is still trying to avoid an outbreak that began in January, and residents of Shanghai are under lockdown and reporting food shortages. آهن.
“New cases need to be addressed,” Crystal Watson, a senior scholar at the Johns Hopkins Center for Health Security, said in a recent interview. “What we see in China is a significant increase in cases, because they didn’t have a lot of exposure, and the vaccine is less effective there.
More than 5.1 billion people – 66.4% of the world’s population – have received at least one dose of the coronavirus vaccine, according to our World Inventory Data Project at the University of Oxford. More than 1.7 billion booster shots or additional medicines are administered globally. But the coverage is very different between different areas. African prices are lower than any continent, with about 20% of people receiving at least one dose.
