EL CAJON (CNS) - A Santee man accused of in the death of his infant daughter pleaded not guilty today to charges of murder and child abuse. Daniel Charles Marshall, 34, was arrested and charged last week in connection with the April 25 death of 7-month-old Hailey Marshall.Paramedics responding to a medical emergency call in the 8600 block of Paseo Del Rey in Santee on April 22 found the child in medical distress, Lt. Thomas Seiver said. She was pronounced dead at a hospital three days later of injuries that included skull fractures, prosecutors said.The circumstances of the death ``warranted further investigation, resulting in the (sheriff's) child abuse unit responding,'' according toSeiver. ``As the investigation progressed, the homicide unit responded and assumed responsibility of the investigation.'' Marshall is being held in lieu of million bail. 874

Dr. Fauci discusses distributing the coronavirus vaccine to the public and returning to "normality": "If you're talking about getting back to a degree of normality, which resembles where we were prior to COVID, it's gonna be well into 2021. Maybe even towards the end of 2021." pic.twitter.com/FHhdWhSsFb— MSNBC (@MSNBC) September 11, 2020 347

During the last few months, many health experts have been talking about reaching “herd immunity” with the distribution of the COVID-19 vaccine. Over the Christmas weekend, Dr. Anthony Fauci said he estimates the country needs to reach 80-85% with the vaccine to attain herd immunity.Here’s what that means.Herd immunity is a concept used in discussions about vaccination, and signifies the threshold needed for a population as a whole to be protected from a virus.The World Health Organization clarifies that herd immunity, or population immunity, “is achieved by protecting people from a virus, not by exposing them to it.”The Mayo Clinic also describes the situation following the 1918 Spanish Flu outbreak. They say people who survived the pandemic were later immune to infection of the H1N1 flu, also referred to as swine flu.Health experts warn that relying on community infection to create herd immunity could be dangerous; there are questions about how long the antibodies created by infection protect against reinfection, and a high level of community infection could lead to overwhelmed medical facilities and a high number of deaths.When the threshold of herd immunity is reached, it means the vast majority of a population is vaccinated and has antibodies, thereby lowering the overall amount of community spread of the virus. It also means portions of the population who cannot get vaccinated are kept safer by the limited spread.What that threshold is varies depending on the virus and the efficacy of the vaccine.According to the WHO, herd immunity against the measles is reached with 95% vaccination, while herd immunity against polio is 80%.Dr. Fauci believes herd immunity for COVID-19 can be reached with around 85% of the population having antibodies. 1778

DUBAI, United Arab Emirates (AP) — Saudi Arabia says this year's hajj will not be canceled, but that due to the coronavirus only "very limited numbers" of people will be allowed to perform the major Muslim pilgrimage. The kingdom said Tuesday that only people of various nationalities already residing in the country would be allowed to perform the hajj. The government did not specify how many people would be permitted to take part. The annual pilgrimage, which is set to begin this year at the end of July, traditionally draws around 2 million Muslims from around the world for five intense days of worship and rituals in Mecca. 639

Doctors and researchers have noticed that the coronavirus affects children differently. Now, there are questions about how accurate COVID-19 tests are in kids.One recent study done by several laboratories and hospitals in Massachusetts looked at the BinaxNOW rapid test.The test had a high accuracy rate in adults, but when it came to symptomatic patients 18 and under, the accuracy rate was just under 78%. The rate decreased in asymptomatic children.Another paper, published in Clinical Microbiology and Infection, found the Panbio rapid test had a lower accuracy rate in children. It was only able to identify 62% of COVID-19 cases in patients under 16 years old.Doctors have differing opinions on why accuracy rates may be different in children.One doctor tells Yahoo News that children's immune systems are just better at zeroing in on diseases and making them harder to detect.A pediatric doctor we spoke with says she hasn't seen a difference in accuracy rates. If anything, symptoms may be different.“Sometimes the way that the disease processes or goes about in these children can change. It can change with obesity rates and things like that, but we have had it be successful with infants age as well as on up,” said Laura-Anne Cleveland with the Rocky Mountain Hospital for Children.There may also be some variation in the way the test is performed. The cotton swab is the same size for both adults and children, which means it could be more uncomfortable for kids.“Kids move around. If you have a little kid that you're trying to hold down, they're going to move around, and sometimes, we don't want to cause pain or cause tears, but you do have to get in that nose, do a couple turns, and be able to get a good sample,” said Cleveland.When children are tested, doctors say it may actually be a bad sign if they are comfortable during the test, because it may not produce an accurate result. If you notice your kid is comfortable while being tested of if the swab barely went into their nose, it's advised that you ask for the test to be redone. 2065
