Chronic Stage: Debilitating effects are now considered long-term. Symptoms include: severe shortness of breath, chronic coughing, physical weakness, occasional fever and sweating at night, decrease in appetite, and general aches and pains. [3] [4] These symptoms develop between four and eight hours after exposure to the antigens.
However, bacterial pneumonia can develop after a viral respiratory infection, usually developing seven to 10 days after the onset of the viral infection. So antibiotics might not be required for ...
People tend to recover from food poisoning in one to two days, but cases can last up to two to four weeks after exposure, said Dr. Pratima Dibba, a gastroenterologist at the Medical Offices of ...
Pneumonia believed to be due to bacteria is treated with antibiotics. [11] If the pneumonia is severe, the affected person is generally hospitalized. [20] Oxygen therapy may be used if oxygen levels are low. [11] Each year, pneumonia affects about 450 million people globally (7% of the population) and results in about 4 million deaths.
Atypical bacteria causing pneumonia are Coxiella burnetii, Chlamydophila pneumoniae (), Mycoplasma pneumoniae (), and Legionella pneumophila.. The term "atypical" does not relate to how commonly these organisms cause pneumonia, how well it responds to common antibiotics or how typical the symptoms are; it refers instead to the fact that these organisms have atypical or absent cell wall ...
Re-exposure to the antigen can help aid in diagnosis. [3] Standardized questionnaires have been created to help in obtaining an exposure history although no official questionnaire has been purported. [13] It has been recommended that the questionnaire administered should be relevant to the region in which the exposure has potentially occurred. [14]
Symptoms begin 12 to 48 hours after exposure to the virus and last for about 1 to 3 days. Even after recovering, infected individuals can be contagious for two more weeks.
Treatment is focused on reversing the cause of inflammation and reducing symptoms. Corticosteroids may be given to reduce inflammation, often before long-term scarring occurs. Antibiotics are usually not helpful or needed, unless there is a secondary infection. Oxygen therapy may be helpful.
