It is very important to know the difference between flu and covid-19 symptoms as they are very similar to each other and this knowledge will guide you in correct identification of the disease and helps you in seeking appropriate treatment.
Similarities and differences between influenza (flu) and COVID-19
Influenza (flu) and COVID-19 are both contagious respiratory infections of the respiratory system but are caused by different viruses. COVID-19 is caused by an infection with a coronavirus (first identified in 2019). And influenza is caused by infection with a flu virus (influenza viruses). These two infections have caused havoc in the world. Let us look at some of the common similarities and differences between them:
Duration of illness
It takes 1 or more days before an infected person starts experiencing the symptoms of illness.
COVID -19 may take a longer duration for the symptoms to start whereas in the case of flu the symptoms begin between 1-4 days.
Duration of the spread of the virus
It is possible to spread the virus for at least 1 day before experiencing any symptoms.
If a person has COVID-19, they could be contagious for a longer time than if they have flu (7 days).
Mode of the spread
Both COVID-19 and flu can spread from person to person between people who are in close contact with one another i.e, within about 6 feet through droplets from sneezing, coughing, or talking.
Though the virus that causes COVID-19 and flu viruses are thought to spread in similar ways, COVID-19 is generally more contagious than flu viruses.
Individuals at risk
Both COVID-19 and flu illness can result in severe illness and complications in older adults, individuals with certain underlying medical conditions, and pregnant women.
COVID-19 seems to cause more serious illnesses in some people resulting in hospitalization and death can occur even in healthy people.
Respiratory complications occur in patients infected with influenza or COVID -19.
Most people who get flu will recover on their own in a few days to two weeks whereas COVID -19 complications can happen even after the recovery (long covid syndrome).
