Corona vs. flu: here’s the difference

Winter has arrived and with it the winter diseases, which this year are going to make some of us sick and interrupt our work and our daily lives. The coronavirus, which has been around since March 2020, will now join the flu, which will worry and confuse many people. How do you know if you have the flu or corona? We have some answers.

Before the coronavirus era, if you suffered from a runny nose, loss of sense of smell, fever, or headache, you thought it was the flu. But now that we are entering winter, how can you be sure you have the flu and not corona?

The bottom line is that you can’t really tell the difference. This is because typical flu symptoms are headache, sore throat, and runny nose – the same symptoms as coronavirus.Hospital staff in the coronavirus ward of Ziv Hospital (Credit: Flash90)


The flu is caused by a different strain of virus than the coronavirus. Still, most coronaviruses, like the flu, cause high fever, muscle aches, headaches, sore throat, runny nose, and fatigue. People with a crown suffer from respiratory symptoms that cause coughing, shortness of breath, shortness of breath, and fever. The infection can also lead to pneumonia, kidney failure, and, in the most severe cases, death.

And what about the symptom most identified with the crown: the loss of smell?

Researchers from Europe whose study was published last year in the journal Rhinology found that when COVID-19 patients lose their sense of smell, it tends to be sudden and severe. In most cases, they do not have a stuffy or runny nose, as most people with coronavirus are still able to breathe freely.

Another thing that distinguishes them is the total loss of taste caused by the loss of smell, which plays an important role in the ability to distinguish flavors. Coronavirus patients who actually experienced loss of taste were unable to distinguish between bitter or sweet.

Onset of infection

Both flu and corona are spread from person to person primarily through an aerosol (aerosol) emitted from coughing, sneezing, and when people speak. Of course, people try not to spit when they speak, but some microscopic droplets can escape.

Still, in most people, flu symptoms generally peak within a day or two after being infected, while a person can show corona signs as early as two to 14 days after being infected. exposition. In both diseases, a person can begin to spread the virus at least a day (and sometimes longer) before the onset of clinical symptoms, but the duration of infection in corona patients is longer than that of influenza.

The solution: vaccines

The best solution, which may still make you wonder which virus you have, is to get vaccinated against both diseases. Don’t worry about getting both vaccines.

The coronavirus vaccine is given by three injections containing mRNA (the last being a booster). According to large and recent studies, it has almost no side effects.

Flu vaccination is done by injecting an attenuated virus into the arm. It is recommended for everyone, but especially for populations at risk, such as children older than six months, pregnant women, immunosuppressed people, and the elderly. The vaccine is completely safe, and side effects are usually pain in the arm where the vaccine was injected.

Additionally, a recent UK clinical trial conducted by the University of Bristol found no danger signs from receiving the flu vaccine in conjunction with the coronavirus vaccine – results that support the research findings of the US health authorities. USA

Long-term effects

Almost everyone who has had the flu knows that once the illness passes, there are no symptoms and you can return to your daily routine. With Corona, it is completely different. It is true that no one wants to wait until after the illness to find out how they will feel, but this will give you an idea of ​​what to expect.

Researchers from the University of Oxford, the National Institute for Health Research (NIHR) and the Oxford Center for Biomedical Research (BRC) recently conducted a study on the extent of the post-Corona, or protracted COVID problem, after examining more of 270,000 people. who have recovered from the virus.

The study found that 37% of recovering patients were diagnosed with at least one persistent corona symptom three to six months after infection, with the most common symptoms being breathing difficulties, abdominal symptoms, fatigue, pain, and anxiety or depression. .
