Corona Virus – Relevant information (as of April 27, 2021) for all scientists at the Max Planck Institute for Mathematics

Posted in

Updated Regulations from the German Government / NRW Government (valid from April 27, 2021):

During the pandemic, regulations are imposed by different sources. The German government imposes the overall rules but the governments of the individual Länder (states in Germany) as well as some cities have the freedom to impose regulations with regard to the particular situation of the area. Here we try to summarize the information relevant for our guests as best as possible and to keep it up to date. We assume no liability for this information and refer to the government websites for the official regulations:

NRW website (only in German), Federal Foreign Office's website, city of Bonn's website.

German Goverment / NRW Goverment regulations

  • UPDATE: From Saturday, April 27, 2021, It is mandatory to wear a FFP2 or KN95 mask by using the public transport.
  • UPDATE: From Saturday, April 24, 2021, Between 10 p.m. and 5 a.m., curfew restrictions apply and you are not allowed to leave your home or your own property. However, there are exceptions, among others for emergencies, the exercise of one's profession or walking the dog. Between 10 p.m. and midnight, it remains permissible to jog, walk or walk the dog, but only alone.
  • UPDATE: From Saturday, April 24, 2021, No public transport during curfew.
  • UPDATE: From Saturday, April 24, 2021, Private meetings are limited to members of a household and a maximum of one other person. Children under the age of 14 are excluded. What is also new is that these contact restrictions also apply to the private sphere, i.e. one's own home.
  • UPDATE: From Saturday, April 24, 2021, Non-contact outdoor sport is only allowed alone, in pairs or in one's own household. Children under 14 years of age may engage in non-contact sports with a maximum of five people.
  • UPDATE: From Saturday, April 24, 2021, Employers must offer home office where possible.
  • it will no longer be possible to enter stores in Bonn that offer goods that go beyond everyday needs with a negative test result for the day. It will then remain within the framework of the emergency brake of the state of NRW for these stores to "click and collect", i.e. pick up ordered goods. Only grocery stores, drugstores, pharmacies and all stores that were previously allowed to enter without a negative test result will remain open.
  • appointments at the city administration / city hall only possible with a negative test result from the same day (self-tests at home are not sufficient).
  • everyone can get tested for free once a week with a rapid test. It is not clear whether you have to be registered in Bonn to do this. Please find more information on where you can get tested here.
  • couples are considered as one household (regardless of their living arrangements)
  • schools and childcare centers are partially open

Medical mask obligation

The new regulation states that it is obligatory to wear a medical mask in stores and doctor's offices. Fabric masks are no longer adequate in these locations. Medical masks in the sense of this regulation are so-called surgical masks, masks of the standard FFP2 or masks comparable to these (KN95/N95).


(regulations from the North Rhine-Westphalia government)
In Germany the individual Länder are responsible for quarantine regulations (in our case NRW). The Länder have put in place their own regulations on the basis of a specimen regulation.
Travelers who are allowed to enter Germany (see below) and have visited a virus-variant area or risk area in the last ten days before entering Germany must register at before arriving in Germany and carry proof of registration with them upon entry. This obligation always applies to those entering the country who have previously stayed in a virus-variant area. Certain exceptions apply for previous stays in other risk areas and high incidence areas. In particular, those who have only passed through a risk area and have not had a stopover there are exempt.
As of March 30, 2021, all persons traveling to Germany by air will generally be required to present a negative Covid-19 test result prior to travel.

Entering/returning from a virus-variant area
There is a transport ban for virus-variant areas. Transport companies e.g. airlines or railroad companies, are not allowed to transport persons from these countries to Germany. Transportation is only possible in narrowly defined exceptional cases, in particular for persons with residence and existing right of residence in Germany, persons who are only transferring in a transit area of a commercial airport, and in a few other special cases. German nationals not resident in Germany should not be denied boarding.
In these exceptional cases, immediately after arrival, travelers are required to go into quarantine for 14 days (starting in the day of departure from one of these areas) and have to report to the Health Department if they show any symptoms. Furthermore, they have to submit a negative test result on entry which is not older than 48 hours. The quarantine cannot be terminated early by getting tested again.

Entering/returning from other risk areas
Travelers have to quarantine for 10 days. The quarantine can be avoided by getting tested for Covid-19 either 48 hours before or within 24 hours after entering Germany and getting a negative test result. A rapid test, "Corona-Schnelltest", is sufficient. You can get tested at airports, test centers, pharmacies or doctors at your own expense.

For arriving at the airports Cologne-Bonn (CGN) and Düsseldorf (DUS), the NRW regulations apply. For travelers who arrive at Frankfurt airport (FRA) the regulations could be different, as it is located in another federal state (Hessen), please check with your airline and with the official regulations of Hessen.

Regulations in Bonn

Bonn has reached the critical number of infected people within 7 days (regions with more than 50 new infections per 100,000 inhabitants in a week are considered as risk areas) and therefore there are the following new regulations in place (additional and expanding on the existing rules):

There is an obligation to wear a face mask in defined (more busy) areas of the city:
In the area of the main station, Bertha-von-Suttner-Platz and Konrad-Adenauer-Platz a mask must be worn between 7 a.m. - 10 p.m..
In other defined areas, a mask must be worn on workdays between 10 a.m. and 8 p.m. There are signs hanging around the city, which signal where to wear a mask. You can see the sign and a list of all the streets where a mask is obligatory here.

Please note that high penalties will be incurred if you do not comply with the regulations!

You can get more information on the city of Bonn's website.

Regulations from us and the Max Planck Society

Information for invited guests

You are still welcome to start your research stay at the institute as planned, but please be aware of the current entry regulations (see above).

Unfortunately, we cannot postpone your visit, since our office space is already fully booked. However, you can shorten your visit if needed. You can also choose the option to reapply through our online application system (no new recommendation letters are needed in this case).

If you have already booked an accommodation and you plan to cancel your stay, please contact the landlord immediately to cancel the rental contract (to avoid costs) and try to find a solution for both sides.

If you have not yet booked a flight or accommodation, please wait before doing so and book only at short notice. We do not know how the situation will change and can only recommend not to book anything yet. If you have booked your flight already, check this link to rebook or cancel for free.

Please be so kind and inform us about your plans by e-mail.
