Add ‘COVID language’ and ‘effervescence’ to the list of possible foreign coronavirus symptoms

• Fever or chills

• Cough

• Shortness of breath or difficulty breathing

• Fatigue

• Muscle or body aches

• Headache

• New loss of taste or smell

• Sore throat

• Congestion or runny nose

• Nausea or vomiting

• Diarrhea

But the CDC notes that this does not cover all possible symptoms. Keep in mind that this is still a relatively new virus that researchers are continuing to investigate in order to understand exactly how it spreads and why some people get very sick and die from it, while others show little or no sign. infection in all.

And some of the other symptoms reported by patients with COVID-19 are quite uncommon, such as swollen or discolored “COVID toes” (pseudo-ulcerative lesions called pernio or chilblains) or rashes that can vary from irregular to blisters that look like chicken pox .

Now, researchers in Madrid are adding some stranger symptoms to that list, after examining 666 infected adult patients at a Spanish field hospital last April. One in four of these patients noticed what is being called a “COVID tongue”, which included bothersome oral problems, such as: swollen and inflamed tongues with notches on the sides; small bumps or irregular areas on the tongue; and swelling of the mouth or sores.

In addition, one in 10 of these patients reported burning sensations in the hands and feet, hives or other painful swelling in those extremities.

The research team presented its results earlier this week, although they were also published as a research letter in the British Journal of Dermatology last September. They warned that the patients analyzed in this study were all adults with COVID-19 pneumonia, so these findings should not be applied to children or asymptomatic individuals. These symptoms should also not be considered a diagnostic tool for coronavirus. Here’s what you should know about the coronavirus test.

British researcher Tim Spector, professor of genetic epidemiology at King’s College London, also tweeted about the COVID language earlier this month. “Seeing an increasing number of Covid tongues and strange mouth ulcers,” he wrote. “If you have a strange symptom or even just a headache and fatigue, stay home!”

He also said that one in five patients with COVID-19 has “less common symptoms”, such as rashes. “Fizzing” is another, which describes the “electric”, “tingling” or “burning” sensations that some coronavirus patients complained on Twitter.

Although researchers have not yet determined the cause of these strange symptoms, one theory is that “the immune system is just having a very hyperactive response to this coronavirus”, as Dr. Purvi Parikh, a pediatric allergist and immunologist at NYU Langone Health, previously reported to MarketWatch. “A lot of the damage the virus does is not really the infection itself; it’s how your immune system reacts to that. “
