A 45-year-old male presents to the clinic with symptoms of fever, dry cough, and shortness of breath. Upon examination, auscultation reveals bilateral crackles in the lungs, and a chest X-ray shows bilateral ground-glass opacities consistent with COVID-19 pneumonia. The patient reports recent travel to an area with a high prevalence of COVID-19 cases and exposure to individuals with confirmed COVID-19 infection. Questions: 1.Which components of the innate immune system are likely involved in the response to this infection? How does the immune response progress through different phases in this scenario?
