One question that gets asked is "have you traveled to another country?" When the answer is "no", then doctors no longer consider diseases that exist in other countries. So that is why they did not understand the parasitic infection until it was too late.
Some of the early symptoms resemble a bad cold.
The parasite that causes malaria (literally "bad air") can only survive in certain species of mosquitos. Those skeeters don't live in Germany. They used to live in the state I live in, but they were exterminated back in the 1950s & 1960s (thanks DDT!). And people from West Africa were naturally/genetically resistant, which was why slaves from that region were preferred over every other race in the southern US where malaria existed until the 1950s & 1960s. If you have 0 copies of the gene then you usually die (of malaria) before puberty. If you have 2 copies of the gene, then you die from sickle cell anemia (usually by your teen years). If you have 1 copy of that gene (another commenter used the term "heterozygote") then the parasite can't live in some of your red blood cells, so you survive to have children.
Germany never had it, and reported being malaria free in 1964. America, in 1970.

Some good info, but some kind of simplistic. I lived in Nigeria for the second half of my childhood in the 80s and 90s and got malaria several times. People come down with it all the time, and typically treat it, and you can recover without treatment also. Most people die from sickle cell anemia when young, but I know multiple outliers who have lived to middle age, and they might live longer yet.
It's easy to test for malaria, if you actually think to test for malaria. In the 90s, we used to hear wild stories from people we knew who would come down with malaria shortly after returning to the USA and doctors and nurses would freak out not knowing what to do about it, and the medication would be expensive to obtain, so the conventional wisdom was also to remember to take a few pills with you on the plane back to the USA!
It's sad but unsurprising that no one was able to treat these German workers in time. When I was a child, there was already talk of strains developing resistance, and this has gotten worse in the 21st century, and the airport workers caught the most deadly strain:
