Coryza, headache and fever. Since the onset of the Covid-19 pandemic, these symptoms have caused even greater concern among people. However, people cannot always be infected with new coronaviruses; the photo is characteristic of other diseases and can cause a great deal of confusion. This is why it is important to know the symptoms of each disease and to increase your prevention habits even further.

Diseases such as covida, flu, cold, sinusitis or dengue are quite common and most have a virus-induced transmission in common. Fever, headaches and body aches, fatigue and discomfort are some of the most common symptoms.

Some signs, such as how symptoms evolve, can also provide some clues, but only one a blood test or a specific laboratory test — or a self-test for the disease — can confirm the diagnosis., health experts have warned. This is a warning: if the flu / breathing symptoms are mild, isolate yourself at home and wait until after that, after all, this is what we have learned over two years of a pandemic. If you experience severe symptoms such as shortness of breath and high fever, seek medical attention.

But does a dominance necessarily mean the flu? And can body aches indicate Covid-19? To clear up any doubts, Live well distinguished the main differences between the diseases.


In all variables, Sars-CoV-2 coronavirus infection can occur without or with no symptoms, which have changed greatly depending on the variant associated with the infection. There are currently five variants of coronavirus that are of concern: alpha, beta, gamma, delta, and omicron.

Covid-19 can come in three forms: mild, moderate, or severe. Diagnosis can be made mainly from clinical and laboratory tests in samples taken from the nose.

The most common symptoms today are fever or chills, dry cough, shortness of breath, fatigue, muscle aches, headache, loss of smell and / or taste, sore throat, nasal congestion or runny nose, nausea, vomiting and diarrhea. .

Studies have shown that two doses of vaccine reduce the duration of symptoms, which is also different from other diseases with similar symptoms.

To relieve the symptoms of Covid-19, you can use over-the-counter medications, such as dipyrone or paracetamol, decongestants (unless there is a specific contraindication to this medicine), cough syrups, and even anti-allergy medications, especially for those who are prescribed. has rhinitis, which can be compensated for by covid infection.

The flu

The flu is caused by a flu virus with hundreds of mutations. Therefore, the flu vaccine should be updated and administered annually.

The disease can have very similar symptoms to covid-19, the difference being that its incubation period is usually shorter, which means that the symptoms appear quickly (often overnight) and the condition worsens. be strict.

The most common symptoms of the flu include cough (usually dry), fever, headache, body aches, and discomfort and fatigue. Sore throat, diarrhea (especially in children), and runny nose or nasal congestion (stuffy nose) may occur.

Flu-relieving treatments include symptomatic medications (antipyretics and painkillers), oral hydration (drinking plenty of water throughout the day), and rest.


The common cold is mainly caused by rhinoviruses that affect the upper respiratory tract and circulate among the population throughout the year. Its incubation period is 1 to 9 days.

Symptoms are usually milder than the flu and last for about four days, with a runny nose, blocked nose, and itching and rarely dry cough, sore throat, and low-grade fever.

There is no specific treatment, it only controls the disease with antipyretics, analgesics, rest and hydration.


Dengue is a very common endemic disease in Brazil. It is a viral infection that is usually transmitted through the bite of a female mosquito infected with a flabibirus. Aedes aegypti (also responsible for transmitting chikungunya virus, yellow fever and zika).

There are four serotypes (DENV-1, DENV-2, DENV-3, DENV-4), each with different interactions with human antibodies. That is, people have four chances of being infected.

Its classic symptom is a high fever, which suddenly appears at the beginning of the infection. Unlike Covid-19, dengue does not usually cause respiratory symptoms, such as runny nose, nasal obstruction, or cough. The disease usually lasts four to ten days, but its effects can last for weeks. It can be non-serious (with or without warning signs) or severe, and the diagnosis can be made by clinical examination and confirmed by a blood test.

Proper treatment for dengue is prescribed by your doctor. Self-medication makes the situation worse. For example, acetylsalicylic acid, which is found in many medicines for fever and headaches, can cause bleeding in people with dengue.


Sinusitis is an acute or chronic inflammation of the sinuses. Viruses or bacteria can cause contamination, heat shock, foreign bodies, and anatomical changes in the nose. Symptoms include headache, severe runny or runny nose, cough, changes in smell, and fever.

Diagnosis is made by physical examination, nasal endoscopy, and imaging tests. Treatment includes nasal or oral corticosteroids, nasal cleansing, antibiotics, or surgery.


Quite common, rhinitis is also an inflammation of the nasal mucosa, acute or chronic. They are mainly caused by allergens (mites), irritable breath (cigarettes or strong odors) and changes in the weather. Symptoms include sneezing, itchy nose and eyes, tight nose, runny nose and watery eyes.

Diagnosis includes medical history, personal and family history of allergies, physical examination, and tests such as allergy and nasal endoscopy. Treatment can be done with corticosteroids and topical or oral antiallergics, nasal cleansing with salt, immunotherapy and environmental control.
