The Relationship Between Chronic Viral Infection and Long COVID
(NIH) In a small study supported by the National Institute of Allergy and Infectious Diseases (NIAID), researchers found that chronic viral infections may influence the likelihood of someone developing Long COVID. They also found that different chronic infections were associated with the development of different Long COVID symptoms. Some viruses cause underlying chronic infections. These viruses […]

Scientists have a theory on covid loss of smell: Damage to nasal cells
(Washington Post) Persistent loss of smell has left some covid-19 survivors yearning for the scent of their freshly bathed childor a waft of their once-favorite meal. It’s left others inured to the stink of garbage and accidentally drinking spoiled milk. “Anosmia,” as experts call it, is one of long covid’s strangest symptoms — and researchers may be one […]

Autopsies Show COVID-19 in the Brain
(MedPageToday) Early this year, leading researchers discussed what we knew — and didn’t know — about COVID-19 and the brain. Since then, new findings have emerged about SARS-CoV-2 and the nervous system, including the results of an autopsy study that showed the presence of the virus throughout the body and brain. How can a respiratory pathogen […]

(Science) SARS-CoV-2 causes profound changes in the sense of smell, including total smell loss. Although these alterations are often transient, many patients with COVID-19 exhibit olfactory dysfunction that lasts months to years. Although animal and human autopsy studies have suggested mechanisms driving acute anosmia, it remains unclear how SARS-CoV-2 causes persistent smell loss in a […]

Long COVID: Could mono virus or fat cells be playing roles?
(AP) A British historian, an Italian archaeologist and an American preschool teacher have never met in person, but they share a prominent pandemic bond. Plagued by eerily similar symptoms, the three women are credited with describing, naming and helping bring long COVID into the public’s consciousness in early 2020.

Higher-Dose Steroids Upped Risk of Death in Non-Ventilated COVID-19
(MedPageToday) Higher-dose corticosteroids increased the risk of death in patients with COVID-19 and hypoxia, and who were receiving either no oxygen or simple oxygen only, compared with usual care that included low-dose corticosteroids, an analysis of the randomized RECOVERY trial showed.

Experiments Show Infection of Visceral Fat Cells May Contribute to Severe COVID-19
(SciTechDaily) Two types of adipocytes (fat cells) were infected in the laboratory: one obtained from human stem cells isolated from subcutaneous tissue and the other differentiated from stem cells taken from visceral fatty tissue. Experiments show that visceral fat – fat around the liver, intestines, and other organs, considered a risk factor for cardiovascular disease, […]

Blood-Related Syndrome Is Being Seen After Developing COVID-19 or Vaccination
(ContagionLive) In a study that was published in Nature Cardiovascular Research yesterday, investigators point out the increased incidence rates in POTS for people who are vaccinated or who have had COVID-19. “We show, in a cohort of 284,592 COVID-19-vaccinated individuals, using a sequence–symmetry analysis, that the odds of POTS are higher 90 days after vaccine exposure than 90 days […]

(Perth Children’s Hospital) PIMS-TS [also known as Multisystem Inflammatory Syndrome in Children associated with COVID-19 (MIS-C)] is a rare but severe complication that occurred in around 1 in 3000 children 2-6 weeks following infection with previously circulating variants of SARS-CoV-2.1 Observed PIMS-TS incidence has been lower following Omicron infection compared with earlier waves.2, 3Consider PIMS-TS in […]

The Covid Pandemic’s Hidden Casualties: Pregnant Women
(NYT) Many expectant women have avoided vaccination, unaware that the virus poses great risks to both fetus and mother. Of all the groups still threatened by Covid-19 — including the elderly and the immunocompromised — it is pregnant women who seem the most unaware of the risks. Covid can kill pregnant women and can result in miscarriage, preterm births and stillbirths […]
