The BRICS TimesCOVID-19 infection changes RNA in male mouse sperm, increasing anxiety in their offspring. Epigenetic inheritance affected hippocampus genes. Human studies needed to check risk to millions of children.
COVID-19 Pandemic’s Long-Term Effects
COVID-19 caused immense damage worldwide. A new study finds the virus alters male mouse sperm, raising anxiety in their next generation. This long-term effect may impact future generations. Scientists at Florey Institute of Neuroscience and Mental Health, Melbourne, Australia discovered this. The study appeared in Nature Communications on October 12.
Study Method: Mouse Experiments
Researchers infected male mice with COVID-19. They then mated these males with healthy female mice. Offspring behavior and health were assessed. First author Elizabeth Kleiman said offspring of infected fathers showed higher anxiety behaviors than offspring of healthy fathers.
Key Findings in Brain Genes
All offspring of infected fathers were affected. Female offspring especially showed changes in hippocampus genes controlling emotions. Scientist Carolina Goobert noted these changes could result from epigenetic inheritance and altered brain development, increasing anxiety.
First Study Showing Long-Term Impact
This is the first study to show COVID’s lasting effects on offspring. The virus changed RNA in paternal sperm, affecting brain development genes. Lead researcher Anthony Hannan emphasized these findings suggest COVID may impact future generations.
Human Implications Require More Research
However, this study was in mice. Hannan warns if these effects apply to humans, millions of children and families worldwide could be affected. This poses a major public health concern.
Broader Impact of COVID: Deaths, Mental Health, and Education
COVID-19 spread in early 2020, causing over 70 lakh deaths per WHO. The true number may be higher. Mental health suffered, especially among youth whose social life was restricted during lockdowns.
A 2023 review in Nature Human Behaviour examined 40 studies across 15 countries. School closures during the pandemic caused long-term academic gaps that children still struggle to fill.
Future Concerns and Immediate Action Needed
This study shows COVID affects not only immediate health but also future generations. Scientists stress understanding life’s beginnings and endings. COVID has altered brain and behavior. Research must identify prevention methods. The pandemic highlighted health as a top priority.
