“…Respiratory tract infections (RTIs) including influen-za are important health hazards among travellers with the incidence of infl uenza in returning febrile travellers from subtropical and tropical regions being between 5 and 15% (Askling H H, et al, 2010;Belderok S M, et al, 2013, Davis X M, et al, 2013. GeoSentinel data for the 2009 pandemic influenza showed that detection of travel-related cases could be a reliable indicator of sustained infl uenza transmission within the exposure coun-try and may aid planning for control measures (Davis X M, et al, 2013). Mass gathering events such as the Hajj pilgrimage, the Olympic Games or the Football World Cup are known to amplify the risk of transmission of respiratory viruses including escalating pandemic infl uenza (Blyth C C, et al, 2010;Haworth E, et al, 2013;Zepeda-Lopez H M, et al, 2010).…”

Viral respiratory infections among Hajj pilgrims in 2013

et al. 2014

Middle East respiratory syndrome coronavirus (MERS-CoV) 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-CoV 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 OC43/229E, 2 (2%) parainfluenza virus 3, 1 (1%) parainfluenza virus 1, and 2 (2%) dual infections. No MERS-CoV 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.

“…Furthermore, it is also important to point out that tourism is not only affected by diseases but is also connected with their spread. The greater mobility of people and the accessibility and affordability of air travel contribute to the rapid spread of infectious diseases (Davis, X.M. et al 2013;Omrani, A.S. and Shalhoub, S. 2015;Findlater, A. and Bogoch, I.I.…”

The effects of COVID-19 on Airbnb

2020

View full text Add to dashboard Cite

COVID-19 pandemic starting at the end of 2019, hit hard tourism and hospitality industries throughout the world. As a part of the processes, the most popular P2P accommodation service, the Airbnb also faced a rapid drop in bookings. This study explores and compares the effects of the first wave of the pandemic on the Airbnb markets of 15 cities. The analysis is based on the data retrieved from Insideairbnb.com. Booking trends are compared between 2019 and 2020 and a day-to-day analysis of occupancy rates during the first months of 2020 is also performed. Special attention was paid to the effects of pandemic on different price categories of listings. The results show that the evolution of local pandemic situation had the most significant impact on bookings and occupancy rates in the investigated cities. The characteristics of local markets and the pandemic and economic situation of sending countries had also great influence on the bookings and cancellations. In addition, in some cases the cancellations did not affect the reservations made for the later periods, meaning that tourists hoped for a quick recovery. The effect on price categories was also different from one location to another. The study provides empirical insights to the effects of the disease on P2P accommodations. Furthermore, the future of short-term rentals is also discussed briefly.

“…These cases can function as sentinels for sustained transmission. 3 Preliminary data from a case-control study found that travellers played a role in introducing influenza infection into New South Wales (NSW) in the 2018-2019 summer period. 4 We aimed to describe travelrelated influenza cases presenting to a single tertiary paediatric hospital in NSW in 2019.…”
