Bacterial infections can get developed whether you have poor hygiene or simply getting in contact with something bacterially contagious. Treating a bacterial infection as soon as possible is very important because this helps to prevent the spread and development of the disease. The worst part in the spread of the disease is that it becomes more expensive and more difficult to treat. Normally, when treating bacterial infections, you need to use a course treatment of antibiotics so as to fully purge the infectious organism from the body. These days, thanks to advanced developments in antibiotic medications, if you buy azithromycin single dose pack, all you need is a single dose of antibiotic to fully treat the infection.
