| 1 | Viral respiratory infections among Hajj pilgrims in 2013显示文摘Middle East respiratory syndrome coronavirus(MERS-Co V) has emerged in the Arabian Gulf region, with its epicentre in Saudi Arabia, the host of the ‘Hajj' which is the world's the largest mass gathering. Transmission of MERS-Co V at such an event could lead to its rapid worldwide dissemination. Therefore, we studied the frequency of viruses causing influenza-like illnesses(ILI) among participants in a randomised controlled trial at the Hajj 2013. We recruited 1038 pilgrims from Saudi Arabia, Australia and Qatar during the first day of Hajj and followed them closely for four days. A nasal swab was collected from each pilgrim who developed ILI. Respiratory viruses were detected using multiplex RT-PCR. ILI occurred in 112/1038(11%) pilgrims. Their mean age was 35 years, 49(44%) were male and 35(31%) had received the influenza vaccine pre-Hajj. Forty two(38%) pilgrims had laboratory-confirmed viral infections; 28(25%) rhinovirus, 5(4%) influenza A, 2(2%) adenovirus, 2(2%) human coronavirus OC43/229 E, 2(2%) parainfluenza virus 3, 1(1%) parainfluenza virus 1, and 2(2%) dual infections. No MERS-Co V was detected in any sample. Rhinovirus was the commonest cause of ILI among Hajj pilgrims in 2013. Infection control and appropriate vaccination are necessary to prevent transmission of respiratory viruses at Hajj and other mass gatherings. | Osamah Barasheed Harunor Rashid Mohammad Alfelali Mohamed Tashani Mohammad Azeem Hamid Bokhary Nadeen Kalantan Jamil Samkari Leon Heron Jen Kok Janette Taylor Haitham El Bashir Ziad A.Memish Elizabeth Haworth Edward C.Holmes Dominic E Dwyer Atif Asghar Robert Booy | 2014 | Virologica Sinica2014，29，6： | 3 |
| 2 | Surveillance of Australian Hajj pilgrims for carriage of potentially pathogenic bacteria:Data from two pilot studies显示文摘AIM To estimate the pharyngeal carriage rate of Neisseria meningitidis(N. meningitidis), Streptococcus pneumoniae(S. pneumoniae) and Staphylococcus aureus(S. aureus) among Australian Hajj pilgrims.METHODS In 2014, surveillance was conducted in two phases among Australian Hajj pilgrims: The first phase during Hajj in Mina, and the second phase soon after returning home to Australia. Nasopharyngeal or oropharyngeal swabs were taken from participants then tested, firstly by nucleic acid testing, and also by standard culture.RESULTS Of 183 participants recruited in the first phase, 26(14.2%) tested positive for S. pneumoniae; 4 had received pneumococcal conjugate vaccine(PCV13). Only one tested positive for N. meningitidis(W). Of 93 2^(nd) phase samples cultured, 17(18.3%) grew S. aureus, all methicillin sensitive, 2(2.2%) grew N. meningitidis(on subculture; one serotype B, one negative), and 1(1%), from an unvaccinated pilgrim, grew S. pneumoniae.CONCLUSION Relatively high carriage of S. pneumoniae and little meningococcal carriage was found. This indicates the importance of a larger study for improved infection surveillance and possible vaccine evaluation. | Mohammad Irfan Azeem Mohamed Tashani Al-Mamoon Badahdah Leon Heron Kristen Pedersen Neisha Jeoffreys Jen Kok Elizabeth Haworth Dominic E Dwyer Grant Hill-Cawthorne Harunor Rashid Robert Booy | 2017 | World Journal of Clinical Cases2017，5，3： | 0 |
