COVID-19: By the numbers


ConnectLocal collected data from more than 15 peer-reviewed COVID-19 studies, including examinations of China, Italy, worldwide, US, and Georgia statistics to provide a to-date compilation of COVID-19's impact and behavior.

Coronaviruses are a family of human and animal pathogens. At the end of 2019, a new strain of coronavirus was identified as the cause of a cluster of pneumonia cases in Wuhan, a city in the Hubei Province of China. It rapidly spread, resulting in an epidemic throughout China, followed by an increasing number of cases in other countries throughout the world. In February 2020, the World Health Organization designated the disease COVID-19, which stands for coronavirus disease 2019. The virus that causes COVID-19 is designated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).


Symptoms of COVID-19 disease:

  • 95% of confirmed case patients had fever

  • 63% of confirmed case patients had dry cough

  • 55% of confirmed case patients had fatigue

  • 36% of confirmed case patients had a productive cough

  • 30% of confirmed case patients had dyspnea (difficult or labored breathing)

  • Symptoms of COVID-19 may appear in as few as two days, or as long as 14 days after exposure.

  • Of confirmed cases in China with identifiable exposure, symptoms developed in 2.5% of infected individuals within 2.2 days and in 97.5 percent of infected individuals within 11.5 days. The median incubation period was 5.1 days


Confirmed COVID-19 Cases

  • 81% of confirmed case patients were considered mild or moderate (not requiring hospitalization).

  • 16% of confirmed case patients were considered critical.

  • 6% of confirmed case patients were hospitalized

  • 2% of confirmed case patients were admitted to ICU.

  • 3% of hospitalized patients received invasive ventilation

  • 21.45% of confirmed case patients have recovered.

  • In the US, 31% of confirmed cases, 45% of hospitalizations, 53% of ICU admissions, and 80% of deaths occurred among adults over the age of 65.

  • The median age of confirmed case patients was 50

  • The mean age of confirmed case patients was 49

  • 1% of Georgia’s confirmed case patients were under the age of 18

  • 59% of Georgia’s confirmed case patients were age 18-59

  • 36% of Georgia’s confirmed case patients were older than 60

  • 42% of confirmed case patients were females

  • 58% of confirmed case patients were females

  • The time between onset of symptoms and recovery for confirmed case patients with mild symptoms is 10-14 days.

  • The average age of a COVID-19 patient that has died in Georgia is 66 years old

  • 80% of COVID-19 fatalities in Georgia had at least one underlying condition

Comorbidities/Underlying Conditions

(the simultaneous presence of two chronic diseases or conditions in a patient)


(Notes: Composite endpoint is a case that results in admission to intensive care unit, or invasive ventilation, or death. CFR is the Case Fatality Rate, which is arrived at by dividing the number of confirmed positive cases by the number of fatalities. This rate provides less-than optimal forecasting figures, as the number of unconfirmed cases are significant due to high numbers of non-symptomatic cases and low numbers of tests conducted; but it is the only rate we can utilize with the figures available)


Studies show that

  • 25% of confirmed cases had at least one underlying condition

  • 8.2% of confirmed cases had two or more underlying conditions

  • 17% of confirmed cases had hypertension; 20% of those with hypertension reached composite endpoint, 6% of those without hypertension reached composite endpoint; the CFR for those with Hypertension is 6%.

  • 54% of confirmed cases had other cardiovascular diseases besides hypertension; the CFR for those with other cardiovascular diseases is 10.5%.

  • 8% of confirmed cases had had diabetes; 23% of those with diabetes reached composite endpoint, 7% of those without diabetes reached composite endpoint; the CFR for those with diabetes is 7%.

  • 2% of confirmed cases had a chronic respiratory system disease; the CFR for those with chronic respiratory disease is 6%.

  • 1% of confirmed cases had a malignancy (cancer); 39% of those with a malignancy reached composite endpoint, 8% of those without a malignancy reached composite endpoint, the CFR for those with a malignancy is 6%

  • 4.5% of confirmed case patients with no underlying conditions reached a composite endpoint

  • 19% of confirmed case patients with one underlying condition reached composite endpoint

  • 28.5% of confirmed case patients with two underlying conditions reached a composite endpoint.

  • The CFR for confirmed cases without any underlying conditions is 0.9%

  • At least one underlying condition was seen in 33% of severe cases, but only 10% of non-severe cases

  • The mean age of confirmed cases with at least one underlying condition is 61, the mean age of confirmed cases without at least one underlying condition is 45.

  • At least two underlying conditions was seen in 40% of severe cases, but only 30% of non-severe cases

  • The mean age of confirmed cases with at least two underlying conditions is 63, the mean age of confirmed cases without at least two underlying conditions is 50.

Fatalities

  • 1% of confirmed case patients died (the Chinese Center for Disease Control and Prevention reports a 2.3% fatality rate in China According to a joint World Health Organization (WHO)-China fact-finding mission, the case-fatality rate ranged from 5.8 percent in Wuhan to 0.7 percent in the rest of China. Most of the fatal cases occurred in patients with advanced age or underlying medical conditions. (seasonal influenza is at about a 0.1% fatality rate)

  • 17% of deaths among were patients between ages 40-60

  • The CFR for confirmed case patients under the age of 6 is less than 0.2%

  • The CFR for confirmed case patients over the age of 80 is 12%, regardless of underlying conditions

  • Statistics on the impact of smoking on the risks of contracting COVID-19, or of worsening the outcomes, are not available due to lack of studies. However, several medical and scientific reports have mentioned that people who smoke are not getting as much oxygen in their lungs as non smokers; the body tries to compensate by making more epithelial lung cells, and because there are more cells overall, there are more cells for the virus to attack.
