But viruses don\u2019t always get less deadly over time.<\/p>\n<p>A variant could also achieve its main goal \u2013 replicating \u2013 if infected people developed mild symptoms initially, spread the virus by interacting with others, then got very sick later, Ray explained by way of example.<\/p>\n<p>\u201cPeople have wondered whether the virus will evolve to mildness. But there\u2019s no particular reason for it to do so,\u201d he said. \u201cI don\u2019t think we can be confident that the virus will become less lethal over time.\u201d<\/p>\n<p>Getting progressively better at evading immunity helps a virus to survive over the long term. When SARS-CoV-2 first struck, no one was immune. But infections and vaccines have conferred at least some immunity to much of the world, so the virus must adapt.<\/p>\n<p>There are many possible avenues for evolution. Animals could potentially incubate and unleash new variants. Pet dogs and cats, deer and farm-raised mink are only a few of the animals vulnerable to the virus, which can potentially mutate within them and leap back to people.<\/p>\n<p>Another potential route: With both omicron and delta circulating, people may get double infections that could spawn what Ray calls \u201cFrankenvariants,\u201d hybrids with characteristics of both types.<\/p>\n<p>When new variants do develop, scientists said it\u2019s still very difficult to know from genetic features which ones might take off. For example, omicron has many more mutations than previous variants, around 30 in the spike protein that lets it attach to human cells. But the so-called IHU variant identified in France and being monitored by the WHO has 46 mutations and doesn\u2019t seem to have spread much at all.<\/p>\n<p>To curb the emergence of variants, scientists stress continuing with public health measures such as masking and getting vaccinated. While omicron is better able to evade immunity than delta, experts said, vaccines still offer protection and booster shots greatly reduce serious illness, hospitalizations and deaths.<\/p>\n<p>Anne Thomas, a 64-year-old IT analyst in Westerly, Rhode Island, said she\u2019s fully vaccinated and boosted and also tries to stay safe by mostly staying home while her state has one of the highest COVID-19 case rates in the U.S.<\/p>\n<p>\u201cI have no doubt at all that these viruses are going to continue to mutate and we\u2019re going to be dealing with this for a very long time,\u201d she said.<\/p>\n<p>Ray likened vaccines to armor for humanity that greatly hinders viral spread even if it doesn\u2019t completely stop it. For a virus that spreads exponentially, he said, \u201canything that curbs transmission can have a great effect.\u201d Also, when vaccinated people get sick, Ray said their illness is usually milder and clears more quickly, leaving less time to spawn dangerous variants.<\/p>\n<p>Experts say the virus won\u2019t become endemic like the flu as long as global vaccination rates are so low. During a recent press conference, WHO Director-General Tedros Adhanom Ghebreyesus said that protecting people from future variants \u2014 including those that may be fully resistant to today\u2019s shots \u2014 depends on ending global vaccine inequity.<\/p>\n<p>Tedros said he\u2019d like to see 70% of people in every country vaccinated by mid-year. Currently, there are dozens of countries where less than a quarter of the population is fully vaccinated, according to Johns Hopkins University statistics. And in the United States, many people continue to resist available vaccines.<\/p>\n<p>\u201cThese huge unvaccinated swaths in the U.S., Africa, Asia, Latin America and elsewhere are basically variant factories,\u201d said Dr. Prabhat Jha of the Centre for Global Health Research at St. Michael\u2019s Hospital in Toronto. \u201cIt\u2019s been a colossal failure in global leadership that we have not been able to do this.\u201d<\/p>\n<p>In the meantime, new variants are inevitable, said Louis Mansky, director of the Institute for Molecular Virology at the University of Minnesota.<\/p>\n<p>With so many unvaccinated people, he said, \u201cthe virus is still kind of in control of what\u2019s going on.<\/p>\n<div id=\"antig-3587496836\" class=\"antig-in-comments_2 antig-entity-placement\"><a href=\"https:\/\/www.facebook.com\/@hadeedmotorsltd\" aria-label=\"Hadeed_WEB_Banner_MG-2\"><img src=\"https:\/\/mlavawteztbj.i.optimole.com\/w:1000\/h:250\/q:mauto\/f:best\/https:\/\/antiguanewsroom.com\/wp-content\/uploads\/2024\/12\/Hadeed_WEB_Banner_MG-2.png\" alt=\"\"  srcset=\"https:\/\/mlavawteztbj.i.optimole.com\/w:1000\/h:250\/q:mauto\/f:best\/https:\/\/antiguanewsroom.com\/wp-content\/uploads\/2024\/12\/Hadeed_WEB_Banner_MG-2.png 1000w, https:\/\/mlavawteztbj.i.optimole.com\/w:300\/h:75\/q:mauto\/f:best\/https:\/\/antiguanewsroom.com\/wp-content\/uploads\/2024\/12\/Hadeed_WEB_Banner_MG-2.png 300w, https:\/\/mlavawteztbj.i.optimole.com\/w:768\/h:192\/q:mauto\/f:best\/https:\/\/antiguanewsroom.com\/wp-content\/uploads\/2024\/12\/Hadeed_WEB_Banner_MG-2.png 768w\" sizes=\"(max-width: 696px) 100vw, 696px\" width=\"1000\" height=\"250\"   \/><\/a><\/div>","protected":false},"excerpt":{"rendered":"<p>By LAURA UNGAR, Associated Press Get ready to learn more Greek letters.
