As gram-positive bacteria, such as for example represented by pneumococcal infections causing lobar pneumonia, can be injected with penicillin for 1 week and will be fully able to achieve a cure. For special pneumonia, such as bacterial pneumonia caused by Staphylococcus aureus, Klebsiella, Pseudomonas aeruginosa, etc., it requires injection of the appropriate antibiotics need to reach 2 weeks, or even about 4 weeks, to be able to get better to reach a cure. In addition, for pneumonia caused by fungal infections, antifungal medication is needed for 4 weeks, or even about 8 weeks, to cure.
