Why 350 Americans died from COVID in a week: Experts explain
"The fact that we're still seeing deaths just means it's still circulating, and people are still catching it," Dr. Tony Moody, a professor in the Department of Pediatrics in the Division of Infectious Diseases at Duke University Medical Center, told ABC News.
Medical experts have suggested a pool of factors that could be blamed for this recent spike in cases and deaths that have been reported as a result of the disease.
According to data released by the CDC, only 23% of adults aged 18 and older received the updated COVID-19 vaccine as of the week ending April 24 in the 2024-25 season. In addition, only 13% of children received the updated vaccine over the same period. This has led experts like Dr. Gregory Poland, a vaccinologist and president and co-director of the Atria Research Institute, to blame low intake of the vaccine as a prime cause of the spike in the number of COVID-related deaths being reported.
Even after taking the vaccine shot, the immune system may fail to develop an appropriate response mechanism. This results in immunity gradually fading over time, increasing the chances of infection.
Age may also be a contributing factor to developing a severe infection. As Dr Poland told ABC News, 'Another reason for death due to COVID is being elderly, being what we call immunosenescent, where you do not have the immunologic ability to respond the same way you did in your 30s and 40s. On top of it, if you do get infected by the time you're in your 70s, 80s, there is some … accumulating co-morbidity."
Hence, those in the age bracket of 65 and above are advised to take two shots of the updated vaccine six months apart from each other.
Another reason for the spike has been blamed on ill-timed treatment measures to counter the disease on patients' end. Doctors fear that many people may avoid seeking treatment until their symptoms become severe which prevents them from detecting the disease in its early stages.
Antiviral pills, including molnupiravir from Merck and Ridgeback Biotherapeutics and Paxlovid from Pfizer, are currently available at pharmacies to help provide suitable treatment for COVID-19. Doses of each of these medications can be started five days from when symptoms first surface. The intake demands four pills of Merck and five pills of Pfizer to be taken twice on a daily basis. Remedesvir is an intravenous medication that can be started seven days after symptoms appear.
"I do think that we don't necessarily make use of the tools that we have on hand in the best way possible," Dr Moody told ABC News. 'I've certainly talked to people who have gotten medications when they got COVID and they made a huge difference. … The trials' data would definitely suggest that the drugs are effective.'
People at high risk of catching the disease are advised to get themselves tested regularly to aid early detection and improvement of any existing infection.
The surge in the NB.1.8.1 variant has reported several cases in Asia, Singapore, and Hong Kong ever since its discovery in China.

Queues grow longer as Noida district hospital battles staff crunch
Noida: The district hospital recorded its highest OPD footfall on Monday, with over 4,366 patients turning up after a three-day holiday break, surpassing last year's record of 4,100. Tired of too many ads? go ad free now Most sought consultations for flu and fever cases or with gynaecologists, leading to long queues and jostling despite additional guards deployed by the administration. "There were more than 1,800 patients at the women's ward OPD. It was a very hectic day for all of us. There is not enough staff and doctors to support this large number of patients. Moreover, doctors also have to visit inpatients," said a senior doctor at the hospital. Officials said the facility has been grappling with a shortage of doctors and nurses for a long time. "The number of staff nurses and doctors is as per the earlier order when the hospital had 100 beds. Since Covid, the capacity has gone up to 240 beds, but the strength of doctors has remained the same. Although some are on contract, the hospital needs more permanent doctors," said an official. Dr Ajay Rana, acting chief medical superintendent, said a requirement has been sent to the state health department. "A demand for 17 more doctors has been sent. Additionally, two more ultrasound machines, one laparoscopy surgeon and equipment, and an MRI machine are also on the list of requirements," he said. At present, the hospital has two functional USG machines, along with CT and X-Ray machines. MRI is not available. According to senior officials, the hospital has 41 permanent doctors, against a requirement of at least 20 more to strengthen paediatrics, gynaecology, medicine, surgery and orthopaedics. Tired of too many ads? go ad free now There are also 20 vacancies for ward boys on contract. The hospital has 124 nurses, with 14 more positions vacant. "The ideal doctor-to-patient ratio is considered 1:4 to 1:6. At the district hospital, the ratio is far lower. Doctors have to manage emergency, OPDs and inpatients across three shifts. While daytime is manageable, nights are a major challenge," said an official. Officials also said that with the OPD shut on Aug 15 and 17 and operating for only half a day on Janmashtami, many patients had turned to emergency services, further straining resources.

US Pediatricians' New Covid-19 Shot Recommendations Differ From CDC Advice
New York: For the first time in 30 years, the American Academy of Pediatrics is substantially diverging from U.S. government vaccine recommendations. The group's new COVID-19 recommendations - released Tuesday - come amid a tumultuous year for public health, as vaccine skeptics have come into power in the new Trump administration and government guidance has become increasingly confusing. This isn't going to help, acknowledged Dr. James Campbell, vice chair of the AAP infectious disease committee. "It is going to be somewhat confusing. But our opinion is we need to make the right choices for children to protect them," he added. The AAP is strongly recommending COVID-19 shots for children ages 6 months to 2 years. Shots also are advised for older children if parents want their kids vaccinated, the AAP said. That differs from guidance established under US Health Secretary Robert F. Kennedy Jr., which doesn't recommend the shots for healthy children of any age but says kids may get the shots in consultation with physicians. Children ages 6 months to 2 years are at high risk for severe illness from COVID-19, and it was important that recommendations continue to emphasize the need for them to get vaccinated, said Campbell, a University of Maryland infectious diseases expert. Vaccinations also are recommended for older children who have chronic lung diseases or other conditions that put them at higher risk for severe disease, the AAP said. The 95-year-old Itasca, Illinois-based organization has issued vaccination recommendations for children since the 1930s. In 1995, it synced its advice with recommendations made by the federal government's Centers for Disease Control and Prevention. There have been a few small differences between AAP and CDC recommendations since then. For example, the AAP has advised that children get HPV vaccinations starting at age 9; the CDC says that's OK but has emphasized vaccinations at ages 11 and 12. But in 30 years, this is the first time the recommendations have differed "in a significant or substantial way," Campbell said. Until recently, the CDC - following recommendations by infectious disease experts - has been urging annual COVID-19 boosters for all Americans ages 6 months and older. But in May, U.S. Health Secretary Robert F. Kennedy Jr. announced that COVID-19 vaccines are no longer recommended for healthy children and pregnant women. A few days later, the CDC issued language that healthy children may get the shots, but that there was no longer a "should" recommendation. The idea that healthy older kids may be able to skip COVID-19 boosters has been brewing for some time among public health experts. As the COVID-19 pandemic has waned, experts have increasingly discussed the possibility of focusing vaccination efforts on people 65 and older - who are among those most as risk for death and hospitalization. A CDC expert panel in June was set to make recommendations about the fall shots. Among the options the panel was considering was whether suggest shots for high-risk groups but still giving lower-risk people the choice to get vaccinated. But Kennedy bypassed the group, and also decided to dismiss the 17-member panel and appoint his own, smaller panel, that included vaccine skeptics. Kennedy also later excluded the AAP, the American Medical Association and other top medical organizations from working with the advisers to establish vaccination recommendations. Kennedy's new vaccine panel has yet to vote on COVID-19 shot recommendations. The panel did endorse continuing to recommend fall flu vaccinations, but also made a decision that led to another notable difference with the AAP. The new advisory panel voted that people should only get flu vaccines that are packaged as single doses and do not contain the preservative thimerosal. The AAP said there is no evidence of harm from the preservative, and recommended doctors use any licensed flu vaccine product that's appropriate for the patient.

Covid Shots for Kids Still Recommended by US Pediatric Group in Break With CDC
The American Academy of Pediatrics updated its recommendations for immunizations Tuesday, including Covid shots for healthy kids, differing from advice from the federal government. The group said it recommends the Covid shot for children ages 6 to 23 months. Earlier this year, Health and Human Services Secretary Robert F. Kennedy Jr. changed course, saying healthy kids and pregnant women should not receive the vaccine. A has released its own recommendations since the 1930s. This year, the group broke from the US Centers for Disease Control and Prevention after Kennedy replaced the members of an influential vaccine panel with people who have spread misinformation around vaccines. The revamped Advisory Committee on Immunization Practices — or ACIP — said it would reevaluate the childhood immunization schedule at a meeting in June. 'The A will continue to provide recommendations for immunizations that are rooted in science and are in the best interest of the health of infants, children and adolescents,' said the group's President Susan Kressly in a statement. In May, the CDC updated its website to say healthy children 'may receive Covid-19 vaccination, informed by the clinical judgment of a health-care provider.' Previously, it recommended everyone 6 months or older get vaccinated. For other vaccines, A removed a hepatitis vaccine that is no longer available, and recommended children under 8 months old receive the RSV vaccine and calls for influenza shots for children as young as 6 months ahead of the flu season. Kids between 9 to 12 years old should receive the human papillomavirus vaccine, up from the previous recommendation of a starting dose at 11 years. The changes in vaccination schedules comes as confusion mounts for parents. ACIP decides which shots will be covered by insurance companies or federally funded through the Vaccines for Children Program. By breaking with ACIP, questions remain on which shots will be covered by insurance or readily available in clinics. 'The A urges every insurer to cover all the vaccines that are included in this immunization schedule,' Kressly said.
