Here is an innovative malaria test. Just stick a patch and we have the result
Malaria is the most common infectious disease in the world, affecting over 220 million people every year - for example, in 2018 it was 228 million cases, which led to 405,000 deaths. Cases outside the endemic areas of this disease (it is worth noting that Poland once belonged to them too) are relatively rare, so as you can easily guess, there are regions where it is a real plague. And that's exactly what happens in Africa, where we see 93% of all cases and 94% of deaths. As with many diseases, quick action is key, but unfortunately testing for malaria means taking a blood sample, testing it in a laboratory, and evaluating doctors.
