Long COVID living in teenagers
Informed by recognized medical guidance
Overview
Long COVID is a condition where symptoms of COVID-19 continue for weeks or months after the initial infection has gone. For teenagers, this can mean feeling tired, having trouble thinking clearly, or other symptoms that make daily life harder. Doctors call it post-COVID-19 syndrome or long COVID. It’s not contagious, but it can be frustrating to live with.
Key facts
- Long COVID can affect teenagers even if their first infection was mild.
- Symptoms can come and go or change over time.
- Most teenagers with long COVID get better with time and support.
- It is not caused by ongoing infection, but by the body’s response to the virus.
- Vaccination reduces the risk of developing long COVID.
Long COVID is not rare in teenagers. Studies suggest that around 5-10% of teenagers who had COVID-19 still have symptoms a few months later. It is less common than in adults, but many teens are affected.
Long COVID can affect any teenager who has had COVID-19, including those who had mild or asymptomatic infections. It is slightly more common in girls than boys, and in teens with certain health conditions, but it can happen to anyone.

Causes
Main causes
- Long COVID is caused by the body’s response to the SARS-CoV-2 virus. The exact reason is not fully understood, but it may involve ongoing inflammation, changes in the immune system, or small blood vessel damage.
- It is not caused by the virus still being active in the body.
Risk factors
- Having more severe COVID-19 during the initial infection
- Having certain health conditions before infection (like asthma, diabetes, or mental health issues)
- Being female
- Being older (teenagers are at lower risk than adults, but still possible)
- Not being vaccinated against COVID-19
When to see a doctor
See a doctor urgently if:
- If your teen has any of the emergency symptoms listed above, call emergency services immediately.
- If symptoms like severe headache, high fever, or very fast heartbeat appear suddenly, see a doctor same day.
Book a routine appointment if:
- If your teen has been feeling tired, having trouble breathing, or other symptoms for more than 4 weeks after COVID-19, make an appointment with their doctor.
- If symptoms are affecting school, activities, or mood, it’s time to talk to a healthcare provider.
- If you are worried about your teen’s health or progress, don’t wait – book a routine checkup.
Diagnosis
There is no single test for long COVID. Doctors make the diagnosis based on your teen’s symptoms, health history, and by ruling out other possible causes. They will ask about when symptoms started and how they affect daily life.
Tests that may be done
- Blood tests to check for anemia, inflammation, thyroid problems, or vitamin deficiencies
- Chest X-ray or lung function tests if breathing is affected
- Heart tests like an ECG or echo if chest pain or palpitations are present
- Tests for other conditions that can cause similar symptoms
What to expect at your appointment
Your doctor will work with you to create a plan. They may refer your teen to specialists like a paediatrician, respiratory doctor, or a long COVID clinic. The process can take time, and it’s important to be patient and keep communicating about how your teen is feeling.
Treatment
Treatment for long COVID in teenagers focuses on managing symptoms and improving quality of life. There is no one medicine that cures it, but a team approach can help. Treatment is tailored to each person’s symptoms.
Self-care at home
- Get plenty of rest and go to bed at a regular time.
- Pace activities – break tasks into small steps and take breaks.
- Stay hydrated and eat a balanced diet with plenty of fruits, vegetables, and protein.
- Gentle movement, like short walks or stretching, as tolerated.
- Keep a symptom diary to share with the doctor.
- Manage stress with relaxation techniques, hobbies, or talking to someone.
Medical treatments
Doctors may suggest therapies like physiotherapy for weakness, occupational therapy to manage daily activities, or speech therapy for brain fog. Pain or sleep problems may be treated with non‑drug approaches first. Some clinics offer psychological support for anxiety or low mood. If needed, a specialist might consider specific medications, but these should always be prescribed by a doctor after careful evaluation.
When is surgery considered?
Surgery is not a treatment for long COVID.
Living with this condition
Living with long COVID means adapting to new limits. Some days may be better than others. It’s important to listen to your body and not push too hard. Talk to teachers about extra time or support at school. Let friends know what you’re going through so they can understand.
Lifestyle tips
- Set a consistent sleep schedule – teens need 8-10 hours a night.
- Eat regular meals with protein, whole grains, and vegetables.
- Stay active within your limits – gentle activity can help, but rest when needed.
- Avoid caffeine and screens before bed to improve sleep.
- Find ways to relax, like reading, music, or spending time with pets.
Diet and exercise
A balanced diet supports recovery. Avoid skipping meals. For exercise, start slowly – try 5-10 minutes of walking or gentle yoga. If exercise makes symptoms worse, stop and rest. Work with a physiotherapist or your doctor to find a safe activity plan. Do not push through extreme tiredness.
Mental health and emotional wellbeing
Long COVID can affect mood and mental health. It’s common to feel frustrated, sad, or anxious. Talk to a trusted adult, friend, or counselor. If you feel very down or overwhelmed, tell someone. Mental health support is part of recovery.
Prevention
You cannot completely prevent long COVID, but you can lower the risk. The best way is to avoid getting COVID-19 in the first place, and if you do get it, vaccination helps reduce the chance of long-term symptoms. Staying healthy with good nutrition, sleep, and exercise also supports your immune system.
Vaccines
COVID-19 vaccines are safe for teenagers and reduce the risk of long COVID. Even if you have already had COVID, getting vaccinated can help protect you from future infections and long COVID.
Screening programmes
There is no routine screening test for long COVID. If you have ongoing symptoms after COVID-19, talk to your doctor.
Complications
If left untreated
- Without proper support, long COVID can lead to missed school, difficulty with friendships, and lower grades.
- It may also cause ongoing fatigue and deconditioning (becoming weaker from inactivity).
- Untreated anxiety or depression can worsen over time.
Long-term outlook
The outlook for teenagers with long COVID is generally positive. Most teens improve significantly within a year, especially with good medical care and support. Some symptoms may take longer, but full recovery is common. With patience and help from healthcare providers, families, and schools, teens can get back to the things they enjoy.
