“…In our study, 8.9% of children with acute SARS-CoV-2 infection (60% during the predominant Omicron variant period) reported subjective olfactory impairment, which is comparable to the finding of a more recent study in children and adults infected with the Omicron variant 9 . Earlier studies, especially during the period when the wild-type or Delta variant were predominant, found subjective complaints in 7–68.4% (mean 22.6%) of the children 3 4 5 6 7 15 16 . However, questionnaires do not seem to be a suitable assessment tool.…”

“…In our study, the frequency of test-based hyposmia in children with acute SARS-CoV-2 infection was 11.1 %, which is significantly lower than that in most other studies. A possible explanation is that in almost all studies, the frequency of hyposmia (varying from 1.9-86.1 %) was assessed only by questionnaires [1][2][3][4][5][6][7][8].

Background Olfactory dysfunction associated with SARS-CoV-2 infection in children has not been verified by a validated olfactory test. We aimed to determine whether these complaints are objectifiable (test-based hyposmia), how often they occur during acute SARS-CoV-2 infection compared to other upper respiratory tract infections (URTI), as well as in children recovered from COVID-19 compared to children with long COVID. Methods Olfactory testing (U-sniff test; hyposmia<8 points) and survey-based symptom assessments were performed in 434 children (5–17 years; 04/2021–06/2022). 186 symptom-free children served as controls. Of the children with symptoms of acute respiratory tract infection, SARS-CoV-2 PCR test results were positive in 45 and negative in 107 children (URTI group). Additionally, 96 children were recruited at least 4 weeks (17.6±15.2 weeks) after COVID-19, of whom 66 had recovered and 30 had developed long COVID. Results Compared to controls (2.7%), hyposmia frequency was increased in all other groups (11–17%, p<0.05), but no between-group differences were observed. Only 3/41 children with hyposmia reported complaints, whereas 13/16 children with complaints were normosmic, with the largest proportion being in the long-COVID group (23%, p<0.05). Conclusion Questionnaires are unsuitable for assessing hyposmia frequency in children. Olfactory complaints and hyposmia are not specific for SARS-CoV-2 infection. The number of complaints in the long-COVID group could result from aversive olfactory perception, which is undetectable with the U-sniff test.

Began from the end of 2019, the SARS-CoV-2 outbreaks in Wuhan, China, this unknown virus are first been recognized and it continues to devastate millions worldwide. As more individual has been infected, Covid-19 has been considered an international public health event and research on its pathogenesis and impacts are necessary. Some research has already shown that the virus can also infect multi organs including human gut enterocytes and the respiratory tract and brings both short-term and long-term effects to humans, the more research has shown the varying immediate symptoms of Covid-19 including acute respiratory distress (ARDS), fever, cytokines storm and long-term risk with the impacts on heart, male reproductive system, neurological and psychological health, and other mysterious risks. In this article, multiple journals and review articles have been researched and managed into long-term and short-term sections, the result shows that Covid-19 has significant impacts on humans for both chronical and instant manifestations.

“…The most frequent symptoms in children are fever, non-productive cough, and intoxication signs (myalgia, nausea, weakness) are possible and less sever than adults [7]. Some children have a sore throat, nasal stuffiness, gastrointestinal symptoms (abdominal pain, diarrhea, vomiting) and smell and taste dysfunction [8]. Respiratory symptoms may include tachypnea, grunting breathing, nasal flaring, enhanced respiratory muscles' function, apnea, cough, and tachycardia, and temperature liability can be noted.…”

Omicron is a newly discovered new variant virus, which spreads rapidly around Russia and the world and has a great impact. It is designated as a variant of concern (VOC) by the World Health Organization. Its characteristic of epidemiology, distribution, pathogenic and clinical diagnosis, treatment, and prevention is still being observed and summarized, and Clinical manifestations of COVID-19 infection are nonspecific, especially in preterm infants. Since there are few reports on the diagnosis and treatment of children with this infection. This article studies the diagnosis, treatment, and prevention of omicron in Russian children, to improve the understanding and attention to the disease.
