Introduction: About 2-3 million pilgrims come to Makkah, Saudi Arabia from all countries to perform Hajj. During the Hajj season of 2019 (1440 H), the total number of pilgrims was 2,489,406, of whom 1,855,027 came from foreign countries. This study aims to investigate the prevalence, pattern, and findings of emergency health problems among pilgrims travelling through King Abdul Aziz International Airport Health Care Center (KAIA-HC) at Hajj Terminal in Jeddah during hajj season of 1440-H. Methodology: A cross-sectional study was conducted by reviewing the medical records of pilgrims coming for treatment at KAIA-HC, before and after Hajj between 1 Dhul Qi’dah to 29 Dhul Hijjah 1440 AH (Corresponding to 4 July to 31 August 2019 AD). The collected data included demographics, medical history, diagnoses of the emergency health problems, infections, and their findings. Data were analyzed using Epi Info 7 and SPSS 25. Results: About 296 (3.87%) of 7,643 pilgrims treated at KAIA-HC were emergency cases. Their average age was 43 years (Standard Deviation (SD) ±7.5); 51.3% were females; the highest (45.3%) was between 30 – 59 years age group, both males and females; the highest two nationalities were Indonesian (14.2%) and Egyptian (12.5%). Diagnoses included hypertension 59(19.9%), bronchial asthma 53 (17.9%), and 23 cases (10.5%) were suffering from hypotension. 16 (5.4%) of patients had a myocardial infarction and 10 (3.4%) had cerebrovascular accidents. In 13 cases (4.4%), a chest infection was reported. Diabetes complications (hyperglycemia, hypoglycemia, and diabetic ketoacidosis) were reported in 28 (9.4%) of the cases. There were 28 (9.5%) surgical diagnoses, 13 (4.4%) were cut wounds, 11 (3.7%) were bone fracture and dislocation, and 4 (1.4%) were head trauma. With regard to the findings, 82 (27.7%) were referred to hospitals; 10 (3.3%) cases required Cardio-Pulmonary Resuscitation, seven of whom survived. The most common referral causes were myocardial Infarction amounting 12(4.05%), followed by cerebrovascular accident 10(3.3%) and chest infection in 8 (2.7%). 13 (4.4%) of the total cases died. The most common causes of death were myocardial infarction, asthma, hypertension and hyperglycemia. Conclusion: Our study emphasizes that emergency cases presented at KAIA-HC were few. Cardiovascular diseases represented the main reason for emergency cases, followed by respiratory diseases. 51% of patients were discharged without the need for a higher level of medical care.

BACKGROUND: Influenza is a highly contagious acute viral respiratory tract infection. The emergence of influenza A(H1N1)pdm09 in 2009 caused a pandemic. Since then it has become a seasonal influenza virus. It causes symptoms ranging from mild to severe illness, which might be fatal, particularly in people with underlying chronic medical conditions, immunocompromised people, the elderly, and pregnant women. OBJECTIVE: Describe the data generated by the influenza A(H1N1) pdm09 surveillance in Saudi Arabia from 2010 to 2016. DESIGN: Retrospective, descriptive. SETTING: Hospitals reporting to the Ministry of Health. MATERIALS AND METHODS: We studied aggregate data on hospitalized cases of influenza A(H1N1)pdm09 in Saudi Arabia between 2010 and 2016. The surveillance system used the case definition proposed by the WHO. The cases were confirmed by performing the real-time PCR (polymerase chain reaction) on upper respiratory samples. MAIN OUTCOME MEASURES: Suspected and confirmed influenza A(H1N1)pdm09 cases. SAMPLE SIZE: 113 502 suspected H1N1 cases and 17 094 (15.1%) confirmed cases. RESULTS: Most of the reported cases were registered in the Riyadh region. During the period of the study, the highest number of confirmed cases, 9262 (54.2 %), was in 2015. The case fatality rate for confirmed cases was 3.6%. CONCLUSION: Influenza A(H1N1)pdm09 showed seasonal trends. The number of suspected influenza cases each year was proportionate to the number of confirmed cases for that year. Riyadh, Jeddah and the Eastern areas (regions with the highest population) reported most of the cases. LIMITATION: Only one strain of H1N1 was tested. CONFLICT OF INTEREST: None.
