\textbf{Short Communication}

Leishenshan Hospital was an urgently built field hospital in Wuhan only
for treating coronavirus disease 2019 (COVID-19) patients. From February
to April 2020, it totally accepted 2011 COVID-19 patients including
20.9\% severe and 79.1\% non-severe cases. At present, it is closed with
a case fatality rate (CFR) is 2.2\% (95\%CI 1.6-3.0\%). Totally 1917
(95.3\%, 95\%CI 94.3-96.2\%) patients were cured with a recovery rate of
86.2\% in severe group and 100\% in non-severe group. On the
8\textsuperscript{th} of April 2020, Wuhan city eased the lockdown
policy after 76 days of the most restrict measurement ever. Herein, we
collected 509 medical records from Leishenshan hospital to share some
commonly interested COVID-19 clinical data. All extracted and summarised
data are showed in table 1.

The origin of the patients covered all 13 districts in Wuhan city. In
our records, 53.2\% (95\%CI 48.8-57.6\%) of the COVID-19 patients were
female, which is slightly higher than Nanshan Zhong \emph{et al} . (Guan
et al., 2020) (41.9\%, 95\%CI 38.9-44.9\%) and the Chinese Center for
Disease Control and Prevention(Novel Coronavirus Pneumonia Emergency
Response Epidemiology, 2020) reported (48.6\%, 95\%CI 48.1-49.0\%)
reported. Most of the patients distributed in the age groups
\textgreater{}50 (66.4\%, 95 CI 62.1-70.5\%) which was consistent with
large scale surveillance reports from China (Guan et al., 2020; Novel
Coronavirus Pneumonia Emergency Response Epidemiology, 2020). Sensory
impairment as a clinical symptom got our attention, since 19.5\% of them
experienced total or partial taste loss and 7.5\% experienced both smell
and taste impairment. There were 42 pet owners in our cases, which only
accounted for a small proportion (8.5\%, 95\%CI 6.0-11.0\%). Most of
them (25) are raising dogs, ten are raising cats, and one of each in
petting chinchillidae, hamster, tortoise, parrot, pigeon, crested myna
and goldfish. 23 patients had animal contact history within the 14 days
prior to showing clinical symptoms including 12 people contacted with
fishes, 10 with chickens and one with bullfrogs. Ten of the patients
were doing animal related occupation such as veterinarians, live animal
market workers, slaughterhouse workers, livestock farmers and farm
workers. Animal contact history did not play an important role in
COVID-19 positivity in our study, even though more evidences showed that
cat and dogs of COVID-19 patients could be infected.(Shi et al., 2020;
Sit et al., 2020) It is recommended that follow-up checking on pets in
the families of COVID-19 patients was essential.

Exposure history records identified 257 patients with known sources of
infection, of whom 69.3\% (95\%CI 63.2-74.8\%) presented fever and
actively sought for a COVID-19 test. A total of 46 patients (17.9\%,
95\%CI 13.41-23.14\%) experienced no unwellness but were identified
through COVID-19 monitoring implementation. They were either
asymptomatic carriers or in their incubation period, if were not
identified, would fuel the pandemic.
