Can Genetics Determine Symptom Presentation?
When it comes to certain diseases, genetics may play a role in whether or not a person experiences symptoms. This is evident in studies conducted on older adults with Alzheimer’s, which have revealed that genetics can contribute to the differences between individuals who display symptoms and those who remain asymptomatic. The same pattern seems to apply to other illnesses, including COVID-19.
Can Asymptomatic Individuals Still Spread Diseases?
When it comes to certain diseases, there is evidence suggesting that individuals without symptoms can still transmit the illness to others. However, the transmission of diseases such as the flu remains a topic of debate among researchers. While some studies indicate that asymptomatic carriers have no effect on transmission, others have found that they can play a significant role in spreading the disease.
