Results
A series of COVID-19 tests,
including SARS-CoV-2 NAT of throat
swabs, chest CT scan and a SARS-CoV-2-specific serological
test,
were conducted on a total of 1,054
obstetrics and gynecology outpatients. Three cases of COVID-19
discovered in the recovery period (2 cases of NAT positive of
SARS-CoV-2, 1 case of IgM and IgG positive of SARS-CoV-2) were excluded
because of the concealment of the infection history, and
1,051
patients were included in the
study. The median age was 38 years old (49-30). A total of 398 patients
were admitted to the hospital for further treatment, 96 patients
underwent outpatient surgery, and 557 persons required health check-ups
due to re-employment and hospital escort requirements. The test result
statistics for all patients are presented in Table I. The SARS-CoV-2
nucleic acid test was negative in all 1051 patients. Nine (9/1051,
0.856%) patients had IgM+ (and
IgG+), which provided a hint of possible asymptomatic infection. The
IgG+ individuals (33/1051, 3.140%) with no history of COVID-19 probably
had recovered asymptomatic SARS-CoV-2 infections.
Seventy-six cases were diagnosed
with abnormal uterine
bleeding-related disease (excluding endometrial malignancy), and 5 of
these patients were 2019-nCoV antibody
positive (see Table 1); the
positive rate was 6.579%, which is greater than the average positive
rate of 3.974%, and the positive rate among patients with other
diseases (2.770%, 3.604%,
4.453%), indicating that such patients may be more susceptible to
SARS-CoV-2. Of 325 patients who
were pregnant, the 2019-nCoV antibody positive rate was 2.770% (9/325),
and the IgM positive rate was 0.615% (2/325), which was the lowest in
the classification of diseases (see Table 1).
No signs of viral pneumonia were found on chest CT scans in the 1051
patients. In 9 patients who were IgM+ (and IgG+), only one patient had a
chest CT scan that indicated ground glass nodules in the right lower
lobe (see Supporting information). All IgM-positive patients were tested
at least twice, and no nucleic acid positivity was found; one case of
IgM positivity turned negative one week later (see Supporting
information). All IgM-positive patients had no fever and no symptoms of
COVID-19, and no SARS-CoV-2 infection was found in the 9 patients’
families. None of the patients admitted to the hospital experienced
SARS-CoV-2 infections during hospitalization.
