Coronavirus Disease 2019 vs. the Flu
https://www.hopkinsmedicine.org/heal...019-vs-the-flu
Influenza “the flu” and COVID-19, the illness caused by the new coronavirus, are both infectious respiratory illnesses. Although the symptoms of COVID-19 and the flu can look similar, the two illnesses are caused by different viruses.
As of Mar. 9, 2020, the flu is showing much more of an impact on Americans than COVID-19. You can find up-to-date information on COVID-19 at the Centers for Disease Control and Prevention (CDC).
Lisa Maragakis, M.D., M.P.H., senior director of infection prevention at Johns Hopkins, explains how the flu and COVID-19 are similar and how they are different.
Similarities: COVID-19 and the Flu
Symptoms
Both cause fever, cough, body aches, fatigue; sometimes vomiting and diarrhea.
Can be mild or severe, even fatal in rare cases.
Can result in pneumonia.
Transmission
Both can be spread from person to person through droplets in the air from an infected person coughing, sneezing or talking.
A possible difference: COVID-19 might be spread through the airborne route (see details below under Differences).
Flu can be spread by an infected person for several days before their symptoms appear, and COVID-19 is believed to be spread in the same manner, but we don’t yet know for sure.
Treatment
Neither virus is treatable with antibiotics, which only work on bacterial infections.
Both may be treated by addressing symptoms, such as reducing fever. Severe cases may require hospitalization and support such as mechanical ventilation.
Prevention
Both may be prevented by frequent, thorough hand washing, coughing into the crook of your elbow, staying home when sick and limiting contact with people who are infected.
Differences: COVID-19 and the Flu
Cause
COVID-19: Caused by one virus, the novel 2019 coronavirus, now called severe acute respiratory syndrome coronavirus 2, or SARS-CoV-2.
Flu: Caused by any of several different types and strains of influenza viruses.
Transmission
While both the flu and COVID-19 may be transmitted in similar ways (see the Similarities section above), there is also a possible difference: COVID-19 might be spread through the airborne route, meaning that tiny droplets remaining in the air could cause disease in others even after the ill person is no longer near.
Antiviral Medications
COVID-19: Antiviral medications are currently being tested to see if they can address symptoms.
Flu: Antiviral medications can address symptoms and sometimes shorten the duration of the illness.
Vaccine
COVID-19: No vaccine is available at this time, though it is in progress.
Flu: A vaccine is available and effective to prevent some of the most dangerous types or to reduce the severity of the flu.
Infections
COVID-19: Approximately 113,579 cases worldwide; 607 cases in the U.S. as of Mar. 9, 2020.
Flu: Estimated 1 billion cases worldwide; 9.3 million to 45 million cases in the U.S. per year.
Deaths
COVID-19: Approximately 3,995 deaths reported worldwide; 22 deaths in the U.S., as of Mar. 9, 2020.
Flu: 291,000 to 646,000 deaths worldwide; 12,000 to 61,000 deaths in the U.S. per year.
The COVID-19 situation is changing rapidly. Since this disease is caused by a new virus, people do not have immunity to it, and a vaccine may be many months away. Doctors and scientists are working on estimating the mortality rate of COVID-19, but at present, it is thought to be higher than that of most strains of the flu.
