COVID-19, also known as the coronavirus disease, has had profound consequences on the health of people in all age groups since its emergence in late 2019. This highly contagious viral illness, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has affected millions of individuals worldwide and has led to significant health challenges and consequences across different age demographics. Though the pandemic has officially ended as declared by WHO, the health side effects of COVID-19 survivors are a concern. COVID-19 survivors, regardless of age, can experience a wide range of consequences on their health following recovery from the disease. Thus, it is absolutely essential to be aware of the health consequences of COVID-19.
COVID in Children
COVID-19, caused by the SARS-CoV-2 virus, affects people of all age groups, including children. However, compared to adults, children generally experience milder symptoms and have a lower risk of severe illness or death from COVID-19.
Children can experience a range of symptoms similar to those seen in adults, such as fever, cough, sore throat, fatigue, headache, body aches, and loss of taste or smell. However, some children may also exhibit unique symptoms like a rash, abdominal pain, vomiting, or diarrhea.
Most children infected with COVID-19 experience mild to moderate symptoms and recover without complications. Severe illness and hospitalization are relatively rare in children, but they can occur, particularly in children with underlying health conditions.
Possible Effects on the Heart:
- Myocarditis: Myocarditis is nothing but inflammation of the heart muscle. COVID-19 can cause myocarditis in children, leading to symptoms such as chest pain, fatigue, shortness of breath, and palpitations. Myocarditis can weaken the heart’s ability to pump blood efficiently and may result in complications like heart failure or arrhythmias.
- Arrhythmias: COVID-19 can disrupt the normal electrical activity of the heart, leading to irregular heart rhythms or arrhythmias. These arrhythmias may range from mild palpitations to more severe conditions like atrial fibrillation or ventricular tachycardia.
- Blood Clotting: COVID-19 can increase the risk of blood clot formation, a condition known as thrombosis. Blood clots can affect the heart by blocking the coronary arteries, leading to a heart attack or impairing blood flow to other organs.
- Impact on Heart Function: In severe cases, COVID-19 can cause significant damage to the heart muscle, leading to decreased cardiac function. This can lead to heart failure, in which the heart is unable to pump enough blood to fulfill the body’s demands.
Children with Existing Heart Conditions:
Children with pre-existing heart conditions may be at higher risk of severe COVID-19 complications. The presence of a heart condition can make it more challenging for the body to cope with the additional stress caused by the viral infection. Such children may experience an exacerbation of their underlying heart condition, leading to worsening symptoms, increased risk of complications, or the need for intensive medical care. Common pre-existing heart conditions that can potentially increase the risk of severe COVID-19 in children include congenital heart defects, cardiomyopathies, and arrhythmias. It is crucial for children with these conditions to receive specialized medical care and adhere to preventive measures to reduce their risk of COVID-19 exposure.
Common Tests for Heart Impact:
- Electrocardiogram (ECG)
- Blood Tests
- Cardiac MRI
Multisystem Inflammatory Syndrome in Children (MIS-C)
While rare, some children develop a condition called MIS-C, which is an inflammatory syndrome that can occur several weeks after a COVID-19 infection. MIS-C can lead to severe inflammation in various body organs and may require hospitalization. Prompt medical attention is crucial if MIS-C is suspected.
Vaccination for Children
As of my knowledge cutoff in September 2021, COVID-19 vaccines were authorized for emergency use or approved for certain age groups. However, vaccine availability and recommendations may have changed since then. It is best to consult the latest guidelines from trusted health authorities regarding COVID-19 vaccinations for children.
Long Term COVID 19
Children with Long COVID experience persistent symptoms that can last for weeks or months after the acute phase of the illness. These symptoms may include fatigue, brain fog, difficulty concentrating, headaches, muscle and joint pain, and respiratory issues. Research suggests that children with underlying health conditions, such as asthma or obesity, may be at a higher risk of developing long-term COVID-19 symptoms. However, even children without pre-existing conditions can experience these effects.
When can they resume normal life?
It is important for children with long-term COVID-19 symptoms to work closely with their healthcare provider to monitor their progress and determine when they can safely resume normal activities. Each child’s situation is unique, and their return to normal life will depend on their specific circumstances and medical advice. Patience and gradual reintegration into regular activities are typically recommended to ensure the child’s well-being and prevent setbacks in their recovery.
COVID in Adults
The Course of Illness
The course of illness in adults with COVID-19 can vary widely. A lot of infected individuals have mild to moderate symptoms and recover without needing to be hospitalized. However, some individuals may develop severe illness. The timeline of the illness generally follows these stages:
- Incubation period: This is the time between exposure to the virus and the onset of symptoms. It typically ranges from 2 to 14 days, with an average of around 5-6 days.
- Mild to moderate symptoms: Common symptoms include fever, cough, sore throat, fatigue, body aches, headache, loss of taste or smell, nasal congestion, and diarrhea. Some individuals may also experience shortness of breath. These symptoms can last for about 1-2 weeks.
- Severe symptoms: In some cases, COVID-19 can progress to severe illness. This can involve difficulty breathing, persistent chest pain or pressure, confusion, bluish lips or face, and an inability to stay awake. Severe cases may require hospitalization and can be life-threatening.
The symptoms of COVID-19 in adults can vary, and some individuals may even be asymptomatic (showing no symptoms). Common symptoms include:
- Fever or chills
- Cough (usually dry, but it can also be productive)
- Sore throat
- Body aches or muscle pain
- Loss of taste or smell (anosmia or ageusia)
- Nasal congestion or runny nose
- Shortness of breath or difficulty breathing
- Diarrhea or nausea
It’s important to note that not everyone infected with COVID-19 will experience all of these symptoms, and some individuals may only have mild symptoms or none at all.
COVID-19 can range in severity from mild to severe, and certain factors can increase the risk of severe illness. Older adults and individuals with underlying health conditions such as heart disease, diabetes, obesity, or weakened immune systems are generally at higher risk for severe illness. Severe cases may require hospitalization, supplemental oxygen, or even intensive care unit (ICU) treatment. In some cases, COVID-19 can be fatal, especially in individuals who are older or have significant underlying health issues. However, it’s important to note that the majority of COVID-19 cases in adults result in mild to moderate illness and recovery.
Possible Effects on the Heart:
- Myocarditis: COVID-19 can lead to inflammation of the heart muscle, known as myocarditis. This can weaken the heart, affecting its ability to pump blood efficiently. Chest pain, shortness of breath, and an irregular heartbeat are all the usual symptoms.
- Arrhythmias: COVID-19 can cause disturbances in the normal rhythm of the heart, resulting in arrhythmias. These irregular heart rhythms may manifest as palpitations, dizziness, or fainting. Severe cases can lead to life-threatening conditions like ventricular fibrillation.
- Acute Coronary Syndromes: In some cases, COVID-19 can trigger acute coronary syndromes, such as heart attacks or unstable angina. The virus can cause blood clots to form, which can block the blood supply to the heart.
- Heart Failure: COVID-19 can exacerbate existing heart failure or induce new cases. The virus puts extra strain on the heart, making it difficult for it to pump effectively. Symptoms of heart failure include fatigue, swelling in the legs, and shortness of breath.
Tests for Impact on the Heart:
- Electrocardiogram (ECG)
- Cardiac biomarkers
- Cardiac MRI
- Coronary angiography
Long term COVID
Long-term COVID-19 can have a profound impact on adults’ physical and mental health, work life, finances, quality of life, and healthcare utilization. Persistent symptoms such as fatigue, respiratory issues, and cognitive difficulties can limit daily activities and work performance. Mental health challenges like anxiety and depression can arise, affecting overall well-being. The condition may disrupt employment, leading to financial strain. Social interactions and relationships can also be affected, diminishing quality of life. Ongoing medical care and consultations become necessary. It is crucial for adults with long COVID to seek appropriate support and medical guidance to manage and mitigate the long-term effects of the illness.
