During the event all participants will be equipped with a Contact Tracer. This constantly measures and recorded the distance to the other participants. This makes it possible to measure the number of critical contacts of each individual participant. Using a special technique, these can also be assigned to specific locations (entrance, grandstand, foyer, etc.) and times. This makes it possible to identify special risk moments and situations during a major event and to identify the focus points for future hygiene concepts.

Furthermore, all participants will be equipped with a fluorescent hand disinfectant. The participants are asked to use it regularly to disinfect their hands. In this way, the disinfectant which deposits on frequently touched surfaces can then be detected by UV light. Therefore, particularly dangerous surfaces can be identified, which can then be given special consideration in future hygiene concepts.

The current COVID-19 pandemic poses a major threat to individual health as well as to the healthcare system and the national economy. In order to avert these dangers, difficult decisions have to be made that significantly restrict normal life. Major events were cancelled early in the COVID-19 pandemic due to the fact that according to current knowledge events in closed rooms pose an increased risk of infection.

However, this is in contrast to the threat to the existence of many athletes and artists who depend on income from spectators. This is not only a threat to the individual actors; the issue also has an overall social dimension, as the existence of entire sports and cultural forms is at risk. The scientific data available to date on infection with respiratory diseases during major events is generally scarce, and for COVID-19 in particular, virtually non-existent.

The RESTART-19 project aims to identify the possible conditions under which artists and athletes can play and perform again after the 30th of September 2020 without endangering the population. In addition, the project will investigate which optimization processes and technical changes may be necessary in the event halls in order to minimize the risk.

We are looking for 4,000 test persons for an experiment that will take place on Saturday, the 22nd of August 2020 in the QUARTERBACK Immobilien ARENA in Leipzig. The experiment will take place from 8.00 to 18.00 hours. Snacks and drinks will be offered during the breaks between the scenarios. During the experiment a concert event will be offered to the audience.

On the day of the test, all test persons will be first checked in. This can take place at three locations: directly at the ARENA or at the Park & Ride car parks of the Leipzig Trade Fair or at the Battle of the Nations Monument. From the Park & Ride car parks, the test persons will be transported to the arena by tram (special trams just for the event). This distribution is intended to realistically simulate the journey and to measure the number of contacts during the journey. Afterwards the first scenario will be simulated. There the test persons will receive information about the course of the further scenarios.

On the day of the test, only persons will be admitted who have not shown any symptoms of COVID-19 within the last 48 hours before the start of the event, who have not been in a risk area and who have not had any contact with COVID-19 infected individuals.

At the check-in on the day of the event, all test persons will be given a respiratory protection mask (FFP2 mask) and a bottle of hand disinfectant. Both must be used during the experiments. FFP2 masks are also used in hospitals as part of the personal protective equipment for the treatment of COVID-19 patients and prevent infection via droplets as well as through aerosols. It is not possible to provide 100% protection, but it can be assumed here that an FFP2 mask collects significant numbers of droplets and aerosols from infected persons that the risk of transmission is extremely low.

During the execution of the experiment, the test persons will be given “Contact Trackers”. These are small transmitters that determine the contact rates and contact distances of the individual participants. The participants must always carry this “Contact Tracer” with them during the experiments. Should there actually be an infected participant among the test persons, the contacts of this participant can be quickly traced.

All participants and helpers must perform a corona test 48 hours before the start of the study.

For this purpose, a smear kit with detailed instructions will be sent to all participants 7-10 days before the start of the study. The test is free of charge.

On Thursday, the 20th of August 2020 you will be required to take a throat swab. If possible, it should be taken to one of the numerous collection points in Leipzig or Halle (we will let you know the exact locations). If you do not have the opportunity to do so, you can also send the sample to the laboratory by post. The appropriate packaging material will be delivered to you. However, participation is only possible with a negative result. If there are delays in the post, admission is unfortunately not possible. We therefore recommend that you use the collection points.

If the test is positive, you will be informed immediately.

The detection of SARS-CoV-2 is done by swabs taken from the mouth or nose. The smear may contain genetic material from the virus. The viral genome is detected by a sensitive molecular test in laboratories tested for the relevant procedures. The complete and complicated name is “Real-Time Reverse Transcriptase Polymerase Chain Reaction” (RT-PCR). The device multiplies the little genetic material in the sample in several cycles. The use of fluorescent substances makes it possible to see whether or not the sought-after gene sequences of the virus are present.

In addition to the University Medical Center in Halle (Saale), the SC DHfK Leipzig and the operating company of the QUARTERBACK Immobilien ARENA Leipzig are involved. Furthermore, security services will be involved to ensure that the solutions and concepts developed are practical and applicable.

Your health will not benefit from participating in this study. You will only receive a smear test for SARS-CoV-2, but the results of this study may help to develop a perspective for many sports clubs and cultural workers on the conditions under which spectators could be admitted to major events again.

There are no costs for your participation in this study. Travel expenses will not be reimbursed. For financial reasons, no expense allowance will be provided.

On the one hand, there are the general risks of a large event. However, the event is registered with the public order office of the city of Leipzig and the usual standards (professional security personnel, fire watch, ambulance service, etc.) will be observed.

In addition, there is a theoretical risk for you to become infected with COVID-19. However, the risk can be classified as very low:

On the one hand, all participants will be tested for SARS-CoV-2 before the event begins. However, these do not provide 100% protection, as the tests may be falsely negative or the viruses may only multiply after the smear has been taken.

Transmission by droplets/aerosols is very unlikely but possible due to the use of FFP2 masks. Due too the general use of masks for all participants, the total leakage will be well below 1%. Theoretically, the use of FFP3 masks would provide even greater protection, but the breathing resistance is so high that there is a risk that participants will not tolerate the masks and will take them off, which would completely negate the protective effect.

During the experiments the masks must be worn the entire time. The masks can only be taken off during outside breaks if the participants keep a distance of 1.5m from each other.

Another transmission path for COVID-19 are smear infections. To prevent smear infections, each participant will be provided with hand disinfectant. Overall, however, smear infections play only a minor role (<10%) in the transmission of SARS-Cov2, so this transmission pathway is unlikely to be effective in people who will frequently disinfect their hands.

During the entire experiment, the participants will be well protected by the masks. Therefore, all situations in which the mask is taken off must be classified as critical. Here, especially eating and drinking are to be mentioned. Since larger distances between the participants are possible outside the hall and, in addition, aerosol-induced transmission is much less likely due to the high dilution, food and drink should be taken outside the hall. Infections outdoors are significantly less frequent than in closed rooms.

Your personal identifying contact data (name, address, telephone number and e-mail address, etc.) are stored strictly separated from the transaction data. We need this information in order to be able to conduct the event in accordance with the requirements of infection protection. This is in the same way, which you must provide information when you visit a restaurant. If a COVID-19 infection is detected in a participant after the event, we will pass on this data to the health authorities.

The transaction data is stored with your participant number, age, sex and postcode of your place of residence but without your personal identifying data. Your participant number is a so-called pseudonym, a randomly generated and unique identification number. Your transaction data, which is thus pseudonymised, is used primarily for scientific publications. In addition, the results will also be published for use in the wider society in a way that can be understood by laypersons. The personal identifying contact data will be deleted after 6 weeks. The remaining data will be kept for another 10 years after completion of the study and then deleted.

The Ethics Committee of the Martin Luther University Halle-Wittenberg has ethically and professionally advised the study. The Commission has not expressed any concerns.

The State Ministry for Social Affairs and Social Cohesion in Saxony has approved the implementation of the study under the submitted hygiene concept.

The public order office of the city of Leipzig has agreed to conduct the study under the given safety and hygiene concept.

Prof. Dr. Rafael Mikolajczyk is responsible for the data processing compliance. The responsible data protection officer is the data protection officer of the Martin Luther University Halle-Wittenberg. You have the right to submit any complaint regarding the study to a data protection authority. In the federal state of Saxony-Anhalt this is the data protection commissioner of the state.

All subjects are insured during participation in the study. This insurance is intended to provide financial protection against possible, albeit very unlikely, damage to the health of study participants directly related to the study.

Insurance cover is provided for health impairments acquired through no fault of one’s own, which occur no later than three years after completion of the study. Existing damage to health or deliberate or grossly negligent behavior by the test person is excluded from insurance coverage. The insurer must be notified immediately of any damage to health that may have occurred as a result of the study. You must provide the insurer with detailed and truthful damage reports and support the insurer in settling the claim. Immaterial damage (e.g. compensation for pain and suffering) shall remain excluded from insurance cover.

Furthermore, commuting accidents are also insured. The insurance coverage extends exclusively to accidents that occur on the direct route between the permanent home and the place of study as well as during the stay in the ARENA. The insurance coverage is not applicable if the normal duration of the journey is extended or if the journey itself is interrupted by purely private or commercial activities (e.g. shopping, visiting restaurants).
