New York, April 29 : Children and young adults with compromised immune systems, such as those undergoing cancer treatment, may experience a prolonged period of infection with SARS-CoV-2, the virus that causes Covid-19, finds a study.
The extended duration of infection may also increase the incidence of mutations, said researchers at the Children s Hospital Los Angeles (CHLA), US.
In the study, published in the journal EBioMedicine, the team described two children and a young adult with acute lymphoblastic leukemia who tested positive for SARS-CoV-2 for months. Lymphoblastic leukemia is a type of cancer of the blood and bone marrow that affects white blood cells.
Immunocompromised children and young adults may experience prolonged SARS-CoV-2 infection
Children and young adults with compromised immune systems, such as those undergoing cancer treatment, may experience a prolonged period of infection with SARS-CoV-2, the virus that causes COVID-19, and the extended duration of infection may increase the incidence of mutations.
This case study was conducted by investigators at Children s Hospital Los Angeles and is published in the journal
EBioMedicine.
Most people are infectious for about 10 days after first showing COVID-19 symptoms. In this study, researchers describe two children and a young adult with acute lymphoblastic leukemia who tested positive for SARS-CoV-2 for months. This is the first report of prolonged infection in a pediatric or young adult population.
