I would say the connection in those countries between china is away more than other countries and they announce and check all the cases carefully not like the rest of the world.
I agree that networking and tourism play a role. Nevertheless, the question must be answered, how well the test is evaluated and which false positive rate actually arises in real use. Increases in supply are also the case for health services. The statement on the question that SARS COV2 is attacking these countries more strongly, which is considered safe, should also be clarified once again. I am pleased with critical answers, as they unleash a discussion.
America and European countries have high air traffic which was the initial mode of Corona virus transmission from China to this other countries. Again majority of the European population is an old population that is already vulnerable to morbidity and mortality due to pandemics such as this one for Covid-19. In other countries especially in African countries majority of the the population is young and remain asymptomatic even after a positive test or have mild symptoms even after a positive test. The fact that European countries have the capacity for testing as opposed to low income countries may also be a reason why the scale of infections is high in European countries.
Honestly, I do not assume that those people are more susceptible due to ethical differences. It is too early to really draw a conclusion, because the virus spreads differently and some countries, especially Europe was hit relatively early. Another important factor is the testing system and the correct reporting on epidemiolocal data. Another factor that likely contributes to the outcome is the healthcare system in the respective country.
I agree with all that Europe and the Americas have enhanced testing capacities, and hence are able to detect asymptomatic cases early enough. The health information system is more advanced with high and efficient tracer rates and reporting. Thus, almost all cases are recorded and reported when compared to other continents and regions like Africa, with weaker health systems, low reporting and poor quality data.
However, we have also learnt that the older generations are more vulnerable to the pandemic. Europe and America have an ageing population, when compared to the African and Asian population that is predominantly young. For instance, and according to (UNFPA, 2015), "Africa has a young age structure, with about two fifths of its population in the 0-14 age bracket and nearly one fifth (19 per cent) in the 15-24 age bracket". On the other hand, the European population has a "constrictive pyramid’, which is typical of developed societies with low fertility and mortality rates and with relatively older populations.
This can also explain why despite the advanced health systems, Europe and America are seen to be hard hit by the COVID-19 Pandemic
In my opinion, our immune system is an important role in preventing us from Covid 19. In addition to it, We need to avoid a close distance from people outdoor. Doing exercise os good for improving your immune system.
