On 27 February 2020, an outbreak of coronavirus 2019 (COVID - 19) resulted in 82 623 confirmed cases and 2858 deaths worldwide, in addition to acute respiratory infections (SARS) (8273
cases, 775 deaths) and Middle East Respiratory Syndrome (MERS) (1139 cases, 431 deaths) were created in 2003 and 2013, respectively.
COVID - 19 is spread across 46 countries around the world.
The total death toll from COVID - 19 is estimated at 3.46% according to published data from the China Center for Disease Control and Prevention (China CDC).
COVID Incubation Time - 19 6.4 days, ranging from 0 to 24 days.
The basic reproductive number (R0) for COVID-19 ranges from 2 to 3.5 in the first phase although there are different speculation models, higher than SARS and MERS.
A study from the Chinese CDC shows the majority of patients (80.9%) who were considered as symptomatic or mild-tempered pneumonia but had a large number of infections in the first phase.
of infection, which had major challenges to contain the spread of COVID - 19.
A total of 3019 health workers became infected on February 12, 2020, accounting for 3.83% of the total number of infections, and burdening the health system,
Limited epidemiological and clinical data suggest that COVID-19 visual disease may be different than SARS or MERS.
We summarize new genetic literature, infectious diseases, and COVID-19 clinics compared to SARS and MERS and emphasize specific diagnoses and possible interventions.
This review will improve our understanding of the various aspects of COVID - 19 and improve our future management practices.
In December 2019, a group of patients with undiagnosed pneumonia were spotted in Wuhan, China.
The novel coronavirus has been identified as the causative pathogen, a temporary term for 1-6 called the novel coronavirus (2019 - nCoV) by the World Health Organization (WHO).
On 11 February 2020, the WHO named the novel coronavirus pneumonia “COVID - 19” (coronavirus 2019).
Based on phylogeny, taxonomy, and established practice, the Coronavirus Study Group of the International Commercial Tax Committee retains the virus as the sister of the strongest respiratory coronavirus
(SARS-CoV) and introduced it as SARS - CoV‐ 2.7 SARS - CoV-2 is a coronavirus-related complication of respiratory-related respiratory infections (SARSr-CoV) and Betacoronavirus.
2 COVID - 19 immediately issued an emergency health warning and spread to 46 countries on 27 February 2020.
‐2 is the seventh member of the coronaviruses family that infects humans.
Like SARS-CoV and Middle East respiratory coronavirus (MERS-CoV) syndrome, SARS-CoV-2 suffers from low respiratory infections and can cause respiratory syndromes (ARDS).
Some human coronaviruses (HCoV 229E, NL63, OC43, and HKU1) suffer from high respiratory infections and the common cold.
On 27 February 2020, according to open data from China CDC as shown in Table 1 and Figure 1, COVID-19 led to 82 623 confirmed cases and 2858 deaths worldwide.
The total number of murder cases is 3.46% as shown in Table 1.

Because COVID - 19 is originally from Wuhan, the capital of Hubei province with a population of nearly 14 million, 58.3% of cases in Wuhan.
1932 health workers contracted the disease in Wuhan alone, 9 of them failing the local health system which led to a high mortality rate (4.42%).
Outside of Hubei province, China as a whole has 13,045 cases, with 109 deaths (0.84%).
Outside of China, COVID - 19 spread to 46 countries and caused 3664 diseases and 67 deaths (1.83%).
Overall, the mortality rate of COVID-19 so far is much lower than SARS (9.6%) or MERS (34.5%) .10 Here, we have summarized the common and unique features of SARS-CoV-2
compared to its two predecessors (SARS-CoV and MERS-CoV) in genes, infectious diseases, clinical features, and they continued to discuss diagnostic challenges and special measures to control COVID-19.
Global distribution of deceased COVID - 19 (27 February 2020)
According to the sixth COVID-19 guidelines for the diagnosis and treatment of COVID-19 by China National Health Commission, SARS-CoV-2 was transmitted through respiratory tract, droplets, contacts and faeces
Chan et al6 reported that six family members received COVID - 19, but none of them contacted Wuhan markets or the animals, although two had visited Wuhan Hospital.
According to data from China CDC, 58.3% of COVID cases - 19 are in Wuhan, and other cases are being brought to Wuhan.
Wuhan is the capital of China's Hubei province, with a population of over 14 million, and is a major transportation hub, connecting people and increasing risk.
Premature ejaculation data followed a significant growth prior to the implementation of government-allocated strategies on 24 January 2020.
The basic birth rate (R0) for COVID - 19 early counts between 2 and 3.5, indicating that one patient can transmit the disease to two other people.
to three, 17-20 was higher than SARS and MERS.
Phylodynamic analysis based on genomic sequence of 52 SARS-CoV-2 virus samples from different countries publicly available on GISAID showed an estimated probability of 7.8 × 10−4
subs / site / year (range 1.1 × 10−4 to 15 × 10 −4), corresponding to SARS and MERS, with the most common ancestral period being 73 days.
The incubation period was around 6.4 days (ranges from 0 to 24 days) .19, 22
