Building Acquired Immunity Against Influenza
Understanding the concept of acquired immunity is essential to comprehend the impact of flu season. Influenza viruses are constantly circulating, but flu season refers to the period when most flu-related illnesses occur. These viruses have the ability to change over time, making it necessary for individuals to develop immunity against them.
Throughout their lives, people are exposed to numerous influenza viruses, resulting in varying levels of immunity. However, the 2020-2021 period witnessed limited exposure to these viruses, which consequently restricted the opportunity for individuals to acquire immunity. As a consequence, the upcoming year may witness more severe flu symptoms due to reduced immunity among the general population. However, accurately predicting the potential impact remains challenging.
Similar Symptoms
When it comes to symptoms, the flu and COVID-19 share many similarities. Both viruses can cause fever and chills, cough, sore throat, headaches, muscle and body aches, fatigue, and congestion with a runny or stuffy nose. It’s worth noting that vomiting, nausea, and diarrhea are more commonly experienced by children. However, one notable difference is that some individuals who contract COVID-19 may also experience a loss of taste and smell, a symptom not typically associated with the flu.
