The CCDC or Chinese Centers for Disease Control and Prevention published a paper with its findings on Coronavirus. The findings revealed that most coronavirus cases are “mild” with individuals with other conditions and older adults to be at the highest risk.
The CCDC’s team performed a study that analyzed the confirmed cases of Coronavirus as of the 11th of February of this year.
The experts identified as “novel coronavirus SARS-CoV-2”. The illness that infection to such a virus is known as COVID-19.
In the recent study, the team obtained all COVID-19 incidents that China’s Infectious Disease Information System was able to record. The scientists contained the following analysis.
- Summary of the patient’s characteristics
- Analysis of the viral spread (sex and age)
- Case fatality rate and death calculations
- Analysis of the viral spread through time, as well as geographical area
- Visual demonstration of the said outbreak and its epidemiological curve
- Summary of incidents that took place outside of Hubei Province in China
80.9% of cases are considered mild
Also, the researchers analyzed 72,314 records of patients. This consisted of 44,672 verified cases, 16,186 alleged cases, 10,567 diagnosed cases, and there are 889 asymptomatic cases.
Of all the overall number of people with confirmed incidents, there is 80.9% that were claimed to be mild. The majority of adults that were involved were between the ages of 30- 79.
Of all the total (confirmed) cases, 1, 023 were fatalities. This is equal to 2.3% death rate. The virus also proved to be more fatal among men at 2.8 percent than women at 1.7 percent.
Less deadly compared to SARS
Notably, the said study observed that the rate for fatality cases becomes higher with age. In particular, up to 39 years of age, fatality percentage is at 0.2%, those aged 40 is at 0.4%, then 1.3% is for people in age 50s, for those of age 60s it is at 3.6% and for those who are in their 70s, it is 8%.
On the other hand, the SARS or Severe Acute Respiratory Syndrome have likened the Coronavirus to have affected a lesser number of individuals from 2002 to 2003. Still, its death percentage was at 145 to 15%, according to WHO.
When it comes to the geo-temporal spread of this virus, it was confirmed by the study that COVID-19 spread outwards from the province of Hubei sometime after December of last year. By the 11th of February 2020, there are 1,386 counties throughout 31 affected areas.
Moreover, they found out the individuals suffering from cardiovascular diseases were at a higher death risk resulting from Coronavirus. This is followed by people with cancer, hypertension, persistent respiratory disease, and diabetes. The authors even noted that there was a downward movement when it comes to the overall curve of the epidemic.
This epidemic curve revealed that the beginning of symptoms and peaked around the 23rd to 26th of January, then started to decline.
They also added that the isolation of entire cities, the transmission of vital information like mask-wearing, promoting handwashing, and care-seeking with elevated frequency across numerous channels, as well as mobilization of multi-sectors fast response groups, are aiding to reduce the said epidemic.
As part of the findings of the study, there were 1,716 health workers in total who were infected, and five of them have died. But, severe cases among the staff in Wuhan had already decreased from 38.9%.
