Welcome to HCM and thanks for your queries... Hi! can you share your blood and chest X-ray reports please? In fact, if I were your physician for this case of chronic chest infection(s), I would like to consider your laboratory parameters as well as any fever, weight loss , productive coughs, chest pain history first of all....! Coming to your question, the viral infection could be acute or chronic. In acute cases it causes high fever, body aches, dry coughs, chills/rigors, muscle/joint pains, skin rashes, gut problems, headaches and bleeding nose/mucosa in some cases! In chronic cases it just causes weight loss, low-grade fever, chronic chest pain, air-hunger/dyspnea, lymph nodes and general weakness, anemia, lethargy etc... Hope I could answer your question; still if you are willing to ask more, I m always here for you! wishing you early recovery!
