A study that was pre-published on Wednesday indicates that a coronavirus mutation is causing the virus to be more contagious, a study authored by the Houston Methodist Hospital found. The study, however, concluded that the virus is not more potent.The study examined 5,000 COVID-19 strains from the Houston metro area. The study found very two distinct waves over the summer.The researchers found that COVID-19 infections from the second wave contained the Gly614 amino acid replacement in spike protein. The researchers said that while this amino acid caused “significantly higher virus loads,” this did not increase the potency of the virus.“We found little evidence of a significant relationship between virus genotypes and altered virulence, stressing the linkage between disease severity, underlying medical conditions, and host genetics,” the study said. “Some regions of the spike protein - the primary target of global vaccine efforts - are replete with amino acid replacements, perhaps indicating the action of selection," according to a summary of the findings.The researchers said that the study is intended to help scientists understand the composition and trajectory of future infection waves.It is important to note that the study has not been peer reviewed, and was limited to cases in the Houston area. 1326

A new invasive tick is spreading through the United States, which is the first time in 50 years a new species has come to the country.The Asian long-horned tick has spread throughout the Eastern Seaboard already, causing mild concern from public health experts, according to The New York Times.The new arrival has yet to be found carrying any human diseases here. Domestic American ticks carry pathogens and transmit them into people rather often."In Asia, however, the species carries a virus that kills 15 percent of its victims," according to the Times.The new ticks are considered a threat to livestock.According to the Times, the long-horned ticks “can multiply rapidly and suck so much blood from a young animal that it dies. The ticks bloat up like fat raisins until their tiny legs are barely able to support them.”So far, the tick has been found in seven states. Experts say the tick is hard to identify."It is an aggressive biter and frequently builds intense infestations on animals causing great stress … and blood loss," according to a statement sent to The Charlotte Observer from the North Carolina Department of Agriculture“Even experts have difficulty distinguishing among tick species, so it is important to take precautions to protect pets, livestock and family members from becoming a host for ticks of any kind,” state veterinarian David Wolfgang told the Pocono Record. “Scientists don’t yet know how this species will adapt to the North American climate and animal hosts, but we know it survived New Jersey’s winter and has infested sheep and cattle in this region.”So far, the tick has been found in Arkansas, Pennsylvania, New York, Virginia and West Virginia.The tick can survive throughout the year, according to the York Daily Record.“We know it can survive very harsh winters. It can handle those winters in other countries, and we know it has survived winters in New Jersey as well,” said Shannon Powers, spokeswoman for the Pennsylvania Department of Agriculture.Dr. Rachel Levine, Pennsylvania's secretary of health, told the Pocono Record people should be cautious when outside.“Ticks can be found in your own backyard, so it is essential to wear long sleeves and pants, use insect repellent containing DEET to help keep you safe from ticks and the diseases they carry. It is also important to check yourself and your pets for ticks, as pets can bring ticks indoors.” 2413
