Lungs are the main organs affected by a COVID-19 infection. A study published in Radiology showed that there is Persistent Lung Damage after recovering from COVID-19. The study of COVID’s long term effects are being studied as more people suffer from Long COVID. Researchers in Germany evaluated changes in lung structure and function in 54 pediatric COVID-19 survivors and nine healthy controls aged 5 to 17 years using low-field MRI. Twenty-nine patients (54%) had recovered from their infections, 25 (46%) had long COVID, and all but one were unvaccinated at the time of infection. Four COVID-19 patients had asymptomatic acute infections. The study findings show that lung abnormalities persist among children who have experienced COVID-19 illness.
Long COVID can cause lingering health problems and wreak havoc for months. Long COVId can include symptoms like, shortness of breath, fatigue and brain fog. The symptoms can come and go, but have an impact on the person’s everyday functioning, and cannot be explained by another health problem. Long COVID can happen in people who have mild symptoms. COVID can cause damage to the lungs, heart, nervous system, kidneys, liver and other organs.
A bad case of COVID-19 can produce scarring and other permanent problems in the lungs but even mild infections can cause persistent shortness of breath — getting winded easily after even light exertion.
Many people recovering from COVID-19 suffer from long-term symptoms of lung damage, including breathlessness, coughing, fatigue and limited ability to exercise. COVID-19 can lead to inflammation in the lungs due to the infection and the immune system’s reaction to it. The inflammation may improve over time, but in some people it persists. Lung recovery after COVID-19 is possible, but takes time. Experts say it can take months for a person’s lung function to return to pre-COVID-19 levels. Breathing exercises and respiratory therapy can help.
