Covid-19 Symptoms for young

A reader has a son in the 20’s who may have been exposed. He is showing some cold like symptoms. The reader wants to know what the common symptoms for an infected young person.

  • “About 4% of children were asymptomatic, 51% had mild illness and 39% had moderate illness. About 6% had severe or critical illness, compared to 18.5% of adults.” [AAP News]
  • “Reported symptoms in children include cold-like symptoms, such as fever, runny nose, and cough. Vomiting and diarrhea have also been reported. ” [CDC]
  • From 10 children tested positive who came from a COVID family, “Five of the children had a cough, four had a sore throat, three had diarrhea and two had nasal congestion and runny nose, symptoms that the researchers said could can make COVID-19 look like other illnesses.” [Physician Weekly]

Testing signs

“All 5 deaths occurred in the SpO2<90% group. Compared with SpO2‚Č•90% group, patients of the SpO2<90% group were older, and showed more comorbidities and higher plasma levels of IL6, IL10, lactate dehydrogenase, and c reactive protein. ” [PubMed]

  • SpO2 units are cheap and some watches have them. Monitoring SpO2 besides monitoring temperature should help. For a young person, 99% would be expected. Below 95% would be concerning.

“The duration from onset of¬†symptoms¬†to hospitalization was 4(2-7) days in symptomatic patients. Fever was occurred in 235(94.3%) patients. A total of 215 (86.3%) patients had been discharged after 16(12-20) days hospitalization. The estimated median duration of fever in all the patients with fever was 10 days (95 confidential intervals [CIs]: 8-11 days) after onset of¬†symptoms. [PubMed]

“The incubation period was more than 14 days for 3 of the 6 second-generation cases. Routes of transmission include respiratory droplets (from case 1 transmitted to case 6, from case 1 to her family members) and closecontact (from case 1 to other cases in her family). ‘ [PubMed]

”¬†As a result, none of the 24 asymptomatic cases presented any obvious¬†symptoms¬†while nucleic acid screening. Five cases (20.8%) developed¬†symptoms¬†(fever, cough, fatigue, etc.) during hospitalization. Twelve (50.0%) cases showed typical CT images of ground-glass chest and 5 (20.8%) presented stripe shadowing in the lungs. The remaining 7 (29.2%) cases showed normal CT image and had no¬†symptoms during hospitalization.” [PubMed]

“The most common¬†symptoms were fever (43.8% on admission and 88.7% during hospitalization) and cough (67.8%). Diarrhea was uncommon (3.8%). ” [PubMed]

Average Age of 41

“The most common¬†symptoms at onset of illness were fever in 48 (77%) patients, cough in 50 (81%), expectoration in 35 (56%), headache in 21 (34%), myalgia or fatigue in 32 (52%), diarrhoea in 3 (8%), and haemoptysis in 2 (3%).” [PubMed]

Across all ages:

”¬†Fever (91.7%), cough (75.0%), fatigue (75.0%), and gastrointestinal¬†symptoms (39.6%) were the most common clinical manifestations, whereas hypertension (30.0%) and diabetes mellitus (12.1%) were the most common comorbidities. Drug hypersensitivity (11.4%) and urticaria (1.4%) were self-reported by several patients. Asthma or other allergic diseases were not reported by any of the patients. Chronic obstructive pulmonary disease (COPD, 1.4%) patients and current smokers (1.4%) were rare. Bilateral ground-glass or patchy opacity (89.6%) was the most common sign of radiological finding. Lymphopenia (75.4%) and eosinopenia (52.9%) were observed in most patients. Blood eosinophil counts correlate positively with lymphocyte counts in severe (r = .486, P < .001) and nonsevere (r = .469, P < .001) patients after hospital admission. Significantly higher levels of D-dimer, C-reactive protein, and procalcitonin were associated with severe patients compared to nonsevere patients (all P < .001).” [PubMed]
