Introduction
Severe respiratory syndrome COVID-19 was a pandemic and novel human pathogen identified in December 2019 and has since been a threat to human health and safety. To date, millions of people have been detected with this virus. The symptoms include fever, cough, shortness of breath, diarrhea, backache, anosmia, and ageusia. This virus was detected in children early, around January 2020, but the complications were very low compared to adults. Up to 20 percent of children did not display the symptoms of COVID-19. Children who showed symptoms typically had mild variants and did not require hospitalization.
Offlate, many children and adolescents have reported long-term symptoms of COVID-19 infection. Persistent symptoms after getting infected with COVID-19 are usually considered post-COVID conditions, post-acute COVID-19, and long-term COVID-19. This long-term effect of COVID-19 is new, ongoing symptoms that develop after the COVID-19 infection and usually continue for four weeks or sometimes more.
There are symptoms associated with it. It usually includes joint pain, fatigue, muscle aches, respiratory problems, palpitations, gastric problems, nausea, seizures, dizziness, and testicular pain. Children under study affected by COVID-19 had at least one of these symptoms.
Common symptoms: The common symptoms of COVID-19 infection in adults and children include cough, fever, shortness of breath, muscle pain, headache, sore throat, loss of taste, and loss of smell. In adults, the most common symptoms were lethargy and shortness of breath, and at least one persisted months after their recovery.
Acute COVID-19 Manifestation.
Before discussing the long-term side effects of COVID-19 infection on children, the acute manifestations included fever, fatigue, and respiratory infection. These symptoms were present with or without any gastrointestinal symptoms. The children who were symptomatic of COVID-19 infection had a fever, vomiting, diarrhea, and cough and also complained of headaches and rhinorrhea.
What Are the Symptoms of Long-Term COVID-19 in Children?
-
General symptoms: The most common symptom of long-term COVID-19 seen in children from the United States included fatigue followed by headache. Studies revealed that Russian children usually developed fatigue and sleep disturbance after getting infected with the COVID-19 virus and had symptoms that lasted more than 120 days. Lack of concentration was also one of the complications after COVID-19 infection. Some children also suffered weight loss as a long-term effect after the COVID-19 infection. The non-hospitalized pediatric population also showed symptoms including headache, nausea, fever, vomiting, insomnia, palpitation, and sensory problems. Weight gain was also seen in children because of lack of exercise and the development of skin conditions such as atopic dermatitis because of lack of exposure to sunlight and staying indoors.
-
Psychiatric: In adolescents, long-term effects of COVID-19 include psychological disorders followed, such as major depressive disorder. Many children suffered from avoidance and also had flashbacks after getting infected with COVID-19 infection. More high school-going children were likely suffering from avoidance and more intrusive behavior. The cases showing depression and anxiety in children have drastically increased after the COVID-19 pandemic. These may have long-term effects on the mental health of the child and impact the overall development of the affected child.
-
Otolaryngeal: The most common otolaryngeal symptom that is affected after COVID-19 infection is anosmia. This symptom is the second most common after the earlier symptom, such as sore, throat, fever, and headache. In some children, anosmia is the most common and severe symptom of COVID-19. This loss of smell was the early presentation of COVID-19 in children, and the effect lasted almost a month. Dizziness was a lesser common symptom of COVID-19 infection. Dysphonia and dysphagia were also seen in very few cases of severe Covid-19 infection. If the symptoms persist for too long an ENT specialist should be consulted. Early intervention and preventing the development of severe complications should be considered.
-
Neurological: Mostly long-term COVID-19 effects included delayed bladder emptying, peripheral neuropathy, ptosis, emotional liability, and weakness of facial muscles. These effects may cause a decrease in physical activity and psychological effects on the child.
-
Cardiovascular: These cardiovascular symptoms after the COVID-19 infection in children lasted almost a month. Chest tightness was common in children suffering from cardiovascular symptoms. Palpitation and variable heart rate were also reported. However, the cardiovascular manifestations were rare.
-
Pulmonary: Respiratory symptoms included a post-viral cough for more than a month. Persistent cough was also documented as a long-term effect of COVID-19 infection in children. Rhinorrhea is the most common respiratory tract symptom after persistent COVID-19 infections. Difficulty in breathing and chest tightness also persisted after the COVID-19 infection.
-
Gastrointestinal: The most common symptoms included diarrhea, abdominal pain and nausea. In some children, persistent abdominal pain was seen even after six months of infection. These symptoms were combined with rash, eye infections, and fever.
Did COVID-19 Affect the Academics of Children?
COVID-19 had effects on the performance of the children affected. Parents reported mental health issues in children and behavior after COVID-19 infection. Children suffered learning loss and reduced basic needs. The infection rates increased, but virtual learning was not affected even after the school reopened. The changes that need to be made include:
-
To develop a secure care and education system for children.
-
Building more schools and having teachers capable of teaching online and by any other suitable and feasible modes for any pandemic. They focus primarily on student learning and general development, including creativity and solving problems independently.
-
Address any inequality or disparity seen in the school regarding infrastructure or funding.
Adapting the system to the world health crisis may focus mainly on child-centered learning, lecture-based school activities, and group discussions and limit the use of traditional lectures.
Conclusion
Some children are at a high risk of developing severe long-term complications of COVID-19. COVID-19 had moderate effects on children, affecting multiple organs. Social environment also has an impact on psychological effects on children. This risk suggests the need for more studies on the long-term effects of COVID-19 on the pediatric population. Children were overlooked during the initial times of COVID-19 as the rate of developing infections was less. The new wave of COVID-19, mostly in children, had long-term effects on the pediatric population. The symptoms are variable but span various organ systems and persist for months.
