Epidemiological information
COVID-19 PCR test was positive in at least one of the family members in
140 (80%) patients. Up to seven people in a family have tested positive
for COVID-19 PCR. The mean number of people who tested positive for
COVID-19 PCR was 2.3 ± 1.4. At least one family member was hospitalized
in 32 (18.3%) patients, 12 (6.9%) of them their mothers, 11 (6.3%) of
them their fathers, 6 (3.4%) of them their grandparents and 3 (1.7%)
of them their siblings.
One hundred and seven (61.1%) of the patients were infected by close
contact with family members diagnosed with COVID-19, 35 (20%) of the
patients were infected via close contact with non-family members
diagnosed with COVID-19, 11 (6.3%) of the patients had a history of
exposure in an epidemic area, including wedding hall, condolence house
and shopping center and 23 (13.1%) of the patients with unknown source
of infection (Table1). Of the family members that are the source of
infection, 44 (41.1%) were mothers, 37 (34.6%) were fathers, 14
(13.1%) were grandparents, 12 (11.2%) were siblings
In half of the 68 patients whose source of infection was outside of
family members, nobody had COVID-19 at home after them, but at least one
person at home was infected with COVID-19 in the other half.
The mean age of patients whose source of infection was outside of family
members and whose source of infection was family members was 12.7±4.9
and 9.3±5.3 respectively (p<0.001). At least one family member
was hospitalized in 31 patients whose source of infection was family
members and at least one family member was hospitalized in patients
whose source of infection was outside of family members
(p<0.001). The mean number of symptoms of patients whose
source of infection was outside of family members and whose source of
infection was family members was 4.5±3.4 and 3.3±2.4 respectively
(p<0.014).
Laboratory information
Within 175 patients, 61 (34.8%) underwent laboratory testing. Among
these patients, leucopenia (White Blood
Count<4.5x109/L) in 11 (%18) patients,
lymphocytopenia (lymphocyte count<1.2x109/L)
in 12 (%19.7) patients, neutropenia (neutrophil
count<1.5x109/L) in three (4.9%) patients
and thrombocytopenia (platelet
count<150x109/L) in five (8.2%) patients
were detected. Furthermore increases in alanine aminotransferase
(>45 U/L) in five patients (minimum 46 U/L, maximum 69 U/L)
and increases in aspartate aminotransferase (>50 U/L) in
three patients (minimum 94 U/L, maximum 115 U/L) were detected, while
decreases in calcium (<8.5 mg/dL) in nine patients (minimum
6.7 mg/dL, maximum 8.4 mg/dL), decreases in sodium (<135
mEq/L) in 13 (21.3%) patients (minimum 129 mEq/L, maximum 134 mEq/L)
and decreases in potassium (<3.5 mEq/L) in three patients
(minimum 3 mEq/L, maximum 3.4 mEq/L) were detected.
Imaging information
Fifty-two patients were underwent chest X-ray. Lung findings were
detected in 19 (36.5%) patients. It was unilateral localized increase
in density in seven patients on the right lower zone, bilateral
localized increase in density in six patients, unilateral mild bronchial
thickening in five patients on the right zone and bilateral diffuse
increase in density in one patient.
