What Long COVID Looks Like in Children and Young Adults


22 May 2023

At least 15 million kids have been infected with SARS-CoV-2, the virus that causes COVID-19, but it is unclear how many of them have had or are living with long COVID. The ailment includes symptoms that linger after COVID-19 or symptoms that come back after an absence of weeks or months. A person might feel short of breath, lose their sense of smell, be unable to think clearly, be tired all the time, or have other maladies that can be traced back to COVID-19.


Rapid Progression of Dementia Following COVID-19


03 May 2023

What you need to know COVID-19 can cause long-term problems with thinking, concentrating, and remembering. This condition is commonly known as “brain fog.” Brain fog after COVID-19 has been studied mostly by observing previously healthy people. In a small study supported by the National Institute of Neurological Disorders and Stroke (NINDS), researchers examined the cognitive impact of COVID-19 on people with dementia. The researchers found that having COVID-19 rapidly accelerated the structural and functional brain deterioration of patients with dementia, regardless of the type of dementia being experienced.


Symptoms of Long COVID Differ for People of Different Racial and Ethnic Groups


06 Apr 2023

What you need to know As the COVID-19 pandemic continues, a growing number of people are experiencing long-term symptoms and health problems following SARS-CoV-2 infection, a condition known as Long COVID. However, the likelihood of being diagnosed with Long COVID seems to vary. A study supported by the Researching COVID to Enhance Recovery (RECOVER) Initiative found that the majority of patients from a sample of more than 30,000 patients with a Long COVID diagnosis were White, non-Hispanic, female, and likely to live in more affluent areas with greater access to health care. Because the COVID-19 pandemic has disproportionately affected people from racial and ethnic minorities, this finding may mean that people from those groups are living with Long COVID without a formal diagnosis.


Antiviral Treatment Reduces Likelihood of Severe Illness From Omicron


09 Feb 2023

hat you need to know Antiviral drugs can lower the risk of severe illness and death from viral infections. In 2021, a clinical trial showed that Paxlovid — an antiviral treatment known generically as nirmatrelvir and ritonavir — reduces the risk of severe COVID-19. Since then, the antiviral treatment has been administered more than 7.6 million times and is available by prescription at more than 40,000 locations in the United States. The study that showed the effectiveness of Paxlovid occurred when the Delta variant was the dominant strain of SARS-CoV-2, the virus that causes COVID-19. In a new study supported by the National Institute of Allergy and Infectious Diseases and the National Cancer Institute, researchers have found that the drug still reduces risk of hospitalization and death from the Omicron variant of SARS-CoV-2.


Bivalent boosters provide better protection against severe COVID-19


08 Feb 2023

To date, more than 80% of people in the U.S. have received at least one dose of a vaccine against SARS-CoV-2, the virus that causes COVID-19. The original mRNA vaccines, developed by Moderna and Pfizer-BioNTech, targeted the initial strain of the virus. Since then, different variants of the virus have evolved. These included Delta in 2020 and Omicron in late 2021. Subvariants of Omicron continue to emerge. Currently, ones called BQ.1, BQ.1.1, and XBB.1.5 predominate in the U.S.

Long-term cardiovascular outcomes of COVID-19


09 Feb 2022

The cardiovascular complications of acute coronavirus disease 2019 (COVID-19) are well described, but the post-acute cardiovascular manifestations of COVID-19 have not yet been comprehensively characterized. Here we used national healthcare databases from the US Department of Veterans Affairs to build a cohort of 153,760 individuals with COVID-19, as well as two sets of control cohorts with 5,637,647 (contemporary controls) and 5,859,411 (historical controls) individuals, to estimate risks and 1-year burdens of a set of pre-specified incident cardiovascular outcomes. We show that, beyond the first 30 d after infection, individuals with COVID-19 are at increased risk of incident cardiovascular disease spanning several categories, including cerebrovascular disorders, dysrhythmias, ischemic and non-ischemic heart disease, pericarditis, myocarditis, heart failure and thromboembolic disease. These risks and burdens were evident even among individuals who were not hospitalized during the acute phase of the infection and increased in a graded fashion according to the care setting during the acute phase (non-hospitalized, hospitalized and admitted to intensive care). Our results provide evidence that the risk and 1-year burden of cardiovascular disease in survivors of acute COVID-19 are substantial. Care pathways of those surviving the acute episode of COVID-19 should include attention to cardiovascular health and disease.




Durability of Anti-Spike Antibodies in Infants After Maternal COVID-19 Vaccination or Natural Infection


07 Feb 2022

COVID-19 vaccination in pregnancy generates functional anti-spike (anti-S) IgG antibodies in maternal circulation that are detectable in umbilical cord blood at birth and can protect the newborn and infant from COVID-19.1-4 Anti-S IgG titers in the umbilical cord are correlated with maternal titers and are highest after late second and early third trimester vaccination.2-4 We characterized the persistence of vaccine-induced maternal anti-S IgG in infant blood and compared persistence of infant anti-S IgG after maternal vaccination vs natural infection.




Association of Major Depressive Symptoms With Endorsement of COVID-19 Vaccine Misinformation Among US Adults


21 Jan 2022

Key Points Question Are major depressive symptoms associated with increased risk of believing common misinformation about COVID-19 vaccines among US adults? Findings In this survey study including 15 464 US adults, people with moderate or greater major depressive symptoms on an initial survey were more likely to endorse at least 1 of 4 false statements about COVID-19 vaccines on a subsequent survey, and those who endorsed these statements were half as likely to be vaccinated. Meaning These findings suggest another potential benefit of public health efforts to address depressive symptoms, namely reducing susceptibility to misinformation.




Characteristics and Outcomes of Hospitalized Patients in South Africa During the COVID-19 Omicron Wave Compared With Previous Waves


30 Dec 2021

On November 24, 2021, a SARS-CoV-2 variant of concern, Omicron (B.1.1.529), was identified in South Africa as responsible for a fourth wave of COVID-19.1,2 The high number of spike mutations has raised concerns about its ability to evade vaccine and spread.3,4 We assessed hospitalized patients with a positive SARS-CoV-2 test result during the fourth wave compared with previous waves.




Why Parents Still Hesitate to Vaccinate Their Children Against COVID-19


15 Dec 2021

As of early December, more than 2.3 million children aged 5 to 11 years had developed COVID-19 and 209 had died. Although a vaccine that’s 90.7% effective in preventing the illness was authorized for younger kids in late October, these figures apparently aren’t convincing enough to persuade many parents to vaccinate their children.
