Background: Hajj attendance increases the risk of respiratory infections including pneumonia. Pneumococcal infections are caused by Streptococcus pneumonia, a gram-positive, catalase-negative organism normally mentioned as pneumococcus. S pneumonia is the most mutual reason of community acquired pneumonia (CAP), bacteremia, otitis media, and bacterial meningitis, in addition to a significant cause of sinusitis, osteomyelitis, septic arthritis, endocarditis, and peritonitis. Complications of each of these diagnoses are common. Clinical symptoms, signs and physical examination findings alone cannot differentiate S pneumonia disease from infections caused by other pathogens. Methods: This was a cross-sectional study among Algerian in al Hajj Pilgrimage. A sample size of 964 Algerian was collected. Data collection took place in September 2016. A structured questionnaire was developed to cover the research objectives. The questionnaire was originally developed in English and then translated into Arabic; its validity was reviewed by selected health care experts and professionals and tested on a sample of the target population.  Selected candidates were interviewed by trained medical students; a brief description of the study. If they agreed to participate, the student administered the questionnaire verbally. Almost 10 minutes were needed to complete the questionnaire. The process continued till the required sample size was completed. Results: All data showed that education is correlated to prevent infection and help them to deal with patient infected with pneumococcus. Conclusion: Before Hajj doctors must teach and inform  all the participants about how to deal with any infectious disease, particularly pneumonia.
