UNDERSTANDING CORONA A pandemic is keeping the world on tenterhooks, with unprecedented implications for human coexistence, science, economics and politics. Every day, knowledge about the SARS-CoV-2 virus, its mutants, and measures to combat the infection grows. Thousands of reports, technical papers, discussions, study results, assessments, and comments reach the public. The information covers basic areas of knowledge - from aerosols and vaccines to winter sports. The target audience is people who want to get information quickly, politicians, authorities, universities, schools, companies, SMEs and businesses. Important sources and links on the pandemic, authorities, ministries and occupational health guidelines are directly available in the book. A VIRUS PARALYZES US The pandemic involving SARS-CoV-2 and known mutations of this virus poses an unprecedented medical and economic challenge to the world's population. Measures to inhibit the spread of the virus are essential until there is sufficient immunization of the world's population. In addition to monitoring the spread of the virus and its gene sequences, consideration of the physicochemical properties of the virus (virus persistence in aerosols, temperature dependence, dependence on humidity and UV radiation) appears relevant to reduce the spread of the virus. WEATHER DEPENDENCE Observations as well as literature reviews suggest a dependence of infection rates on weather conditions is likely. PROPOSED SOLUTIONS to exit LOCKDOWN. Proposed solutions for returning to a normal daily routine are provided. We try to explain the pandemic and make it understandable and give people a perspective on a daily life with the virus. There is also advice for politicians to encourage thoughtful reactions. Translated with www.DeepL.com/Translator (free version)

Unpredecentend challenge
The pandemic with SARS-CoV-2 and the known mutations of this virus poses an unprecedented medical and economic challenge to the world population.
Our team is very activ, information, vaccination, treating.
In addition to monitoring the spread of the virus and its gene sequences, consideration of the physicochemical properties of the virus (virus persistence in aerosols, temperature dependence, dependence on humidity and UV radiation) appears relevant to reduce the spread of the virus.
Weather Dependency
Observations, as well as literature reviews, make it likely that infection rates are dependent on weather conditions.
On the one hand, exploding knowledge - on the other, an immense need for information.
While researching this topic, we noticed that there is no easy-to-read guide to the corona virus and the pandemic. That is why we decided to write this little book.
No flu wave in Germany in 2021
This year, Germany seems to have been spared the usual usual flu season. Shortly before the end, the so far 519 laboratory-confirmed cases as defined by the Working Group on Influenza (AGI) at the Robert Koch Institute (RKI) are not enough to speak of the beginning of a flu wave.
There hasn't been a flu epidemic at all. This, he said, is a first since flu surveillance began in 1992 by the working Working Group.
Most other countries in the northern hemisphere have also been spared the wave.

Understanding CORONA
A pandemic keeps the world in suspense and has unprecedented effects on the coexistence of people, science, economy and politics.
Every day, knowledge about the SARS-CoV-2 virus, its mutants and measures to combat the infection grows. Thousands of reports, technical papers, discussions, study results, assessments and comments reach the public.
Temperature, relative humidity and UV radiation strongly influence the infection rate with the corona virus. The influence of the seasons on new infections with the Corona virus has now been scientifically proven.
The information covers basic areas of knowledge - from aerosols and vaccines to corona-tests.
The target group is people who want to inform themselves quickly, medium-sized businesses and companies. Important sources and links on the pandemic, authorities, ministries and occupational health guidelines are directly available in the book. They are updated regularly.
INSPIRATION FOR THIS BOOK
Incidence numbers are correlating with geographical altitude
The distribution of new infections in Germany is reminiscent of an elevation relief map. This coincidence could be by chance, nevertheless it seemed worth considering an analysis of previous publications.
Can corona virus infection and disease be related to meteorological data, specifically air temperature, water vapor saturation and UV radiation?
Based on our observations, we developed this working hypothesis:
There is a correlation between disease incidence, air temperature, water vapor saturation and UV radiation.
There may still be mathematical factors that influence this number, but essential are the factors that are present in the atmosphere, temperature, relative humidity and UV radiation.
COVID-19 DISTRIBUTION RELEVANT TO ALTITUDE?
When reading the development of the Corona figures on a daily basis the distribution of new infections in Germany is reminiscent of an elevated high-altitude relief map of Germany. Austria and Switzerland show similar pictures.
This coincidence could be coincidental, nevertheless it seemed worth considering an analysis of previous publications to be performed. Is there any relation of the disease to the meteorological data, especially the air temperature, water vapor saturation and UV radiation?
Based on our observations, we developed the working hypothesis:
There is a correlation between COVID-19 incidence, air temperature, water vapor saturation and UV radiation.
Switzerland and Austria show similar pictures
CORONA IN THE MOUNTAINS
FACT
Temperature decreases with altitude, in dry air more than in clouds.
Up to the end of the troposphere at an altitude of about 11 km, the temperature decreases evenly in a linear fashion, always assuming that the weather is stable weather situation.
Basics:
per 100 meters, the temperature decreases by about 1°C in dry air. When this air mass condenses during the ascent due to cooling energy is released.
This process lowers the cooling rate of rising air per 100 m to approx. 0.7 °C. In the process, the air becomes dryer.
Temperature and Pressure Rates
In addition an analysis of the meteorologically and geographically given conditions: Different sea levels should be seen epidemiologically differently. Temperature, humidity and UV radiation are different at different altitudes.
Another point that can influence the spread of the virus is the air flow.
In strong air currents (westerly wind, easterly wind), the virus is transported by the wind in an aerosol with a lifespan of up to four days.
Air currents can also lead to a deviation of the congruence of the Corona infection map with the geographic relief map, depending on the wind direction, air currents cantilever over the mountains and transport viruses in aerosols.
STUDY FROM CHINA
While searching for correlations, we found a study from China on the Internet with an interesting result:
1 °C increase in temperature makes a reduction in the infection rate from 3 %
The relationship of temperature and humidity to the incidence of COVID-19 infection/disease is not consistent; however, in the literature several studies have shown a decrease of infections.
The work of Wu (Effects of temperature and humidity on the daily new cases and new deaths of COVID-19 in 166 countries ) describes effects that may be consistent with the observations described above.
Effects of temperature and humidity on the daily new cases and new deaths of COVID-19 in 166 countries
