‘Covid nails’ – strange symptoms after infection – VnExpress

“Covid nails” are strange spots on the nails, which are seen as residual side effects, or the body’s way of dealing with a large-scale viral infection.

Doctor, Doctor Hoang Thanh Tuan (Deputy Dean of Plastic Surgery Department, National Institute of Burns), founder of an online support consulting group to take care of F0 at home, is treating a baby 9 years old. After recovering from Covid-19, the baby appeared strange marks on his nails, including vertical lines, with depressions across the nail. This condition lasted for many days, the patient had no other symptoms, his health was normal.

Doctors call this phenomenon “Covid nails”, which is quite rare. This condition appears within days, weeks or even months after F0 has recovered, indicating that the patient’s body has undergone a process of fighting infection, damaged blood vessels, risk of blood clots. high blood.

There are three morphological forms of “Covid nails”, the first is horizontal, concave lines across the nail; the second is the “red half moon” nail shape; the third is a nail with horizontal or vertical mees. This phenomenon can appear not only in the fingernails but also in the toes. The most characteristic sign is the grooves, usually white, running along the nail of the patient.

The doctor thinks that the phenomenon of “Covid nails” will gradually recover after about 6 months, not dangerous, so there is no cause for concern. If you encounter this situation, you should take care of your nails a lot and limit the use of chemicals. It is not clear how many people have this sequelae after recovering from Covid.

In the world, “Covid nails” are also called “Beau lines” by doctors., recorded and viewed as a side effect of Covid-19. The exact cause is still unknown, but experts believe that experiencing stress or illness that seriously affects the overall health of the body can affect the condition of the nails.

The sequelae of Covid is a global health issue of concern and is still considered an “unsolved mystery”. Experts around the world are still working to learn more about the short- and long-term health effects associated with post-Covid-19.

According to Dr. Tuan, after recovering from Covid-19, patients may experience a series of disorders and sequelae for about four weeks or more. Even people who do not have Covid-19 symptoms for days or weeks after being infected can still have sequelae. These conditions may present in different forms and may present at the same time or for different periods of time.

Some symptoms that may be experienced are shortness of breath or shortness of breath; fatigue or dizziness. Symptoms are worse after physical or mental activity (also called post-exercise malaise). In addition, they have trouble thinking or concentrating (sometimes called a “brain fog”); cough; chest or stomach pain; headache; fast or pounding heartbeat (also known as palpitations). The sequelae may also be muscle or joint pain; tingling sensation; diarrhea; having trouble sleeping; fever; dizziness when standing up or changing positions suddenly (vertigo). The patient may develop a rash; mood swings; changes in taste and smell; changes in the menstrual cycle.

“Any age who has had Covid-19 can then develop persistent Covid-19 syndrome, however sequelae are less common in children and adolescents than in adults,” said Dr. said. Studies have shown that symptoms persist in children to be similar to symptoms in adults, most commonly fatigue, headache, trouble sleeping (insomnia), difficulty concentrating, muscle and joint pain, and cough. Young children may have difficulty describing problems they are having.

Doctors recommend that the best way to prevent Covid-19 sequelae is to prevent Covid-19 disease by vaccination and compliance with regulations on disease prevention.
