US health officials pointed out that this is a sign of COVID-19 infection and urgent medical attention is needed because there is too little oxygen in the blood or the blood does not circulate.

Therefore, if a patient infected with COVID-19 finds that their lips, skin, or nails have turned gray, they should contact a health care center immediately.

Since the beginning of the pandemic, US health officials have pointed out this as a potential sign of the need for urgent medical care, despite recent claims that it only applies to the Omicron variant.

The CDC has identified 11 different symptoms-including headache, sore throat, nausea… However, the National Health Service (NHS) still only recognizes 3 warning symptoms of COVID-19: high fever, persistent cough, and loss of taste/olfaction .

Research in the United Kingdom shows that the COVID-19 vaccine is a “game changer” that makes more infected people have milder symptoms than recommended 3. However, the NHS still does not regard changes in the color of lips, skin or nails as a warning sign. Urgent medical attention is required. They only warn children that if they have skin conditions such as pale skin, hives, paleness or graying, they should call 911 immediately.

In the guidelines updated in February last year, the CDC stated that graying of lips, skin, and nails may be a symptom of COVID-19.

This symptom is accompanied by dyspnea, chest tightness or chest tightness, confusion, loss of consciousness, but not alertness.

The agency said: “If anyone has any of these signs, please seek emergency medical assistance.”

Gray skin and lips (called cyanosis in medicine) are warning signs of insufficient oxygen in the blood or poor circulation.

It may be related to other serious health problems, such as asthma, pneumonia or heart disease.

This symptom usually only appears in the later stages of COVID-19.

Onychomycosis may be a warning sign of iron deficiency, which means that the body organs are not getting enough oxygen.

But this sign may also be the result of trauma, smoking, fungal infection, or frequent contact with water or detergents.

The NHS COVID-19 warning list is often criticized for too few symptoms. It lists only three possible signs.

However, according to ZOE, the COVID-19 symptom tracking app for 1 million Britons, the other four common symptoms to be aware of are runny nose, headache, sneezing and sore throat.

They said: “Many people still don’t know all the symptoms of COVID-19 they need to look for. This often misleads them into thinking that they just have a cold, when in fact they may have an underlying disease. This disease.”
