Here's a very short list of airborne diseases:
Tuberculosis: present in 25% of world population, infects 1% of world population per year, with 1.5 million deaths per year
Pneumonia: 450 million cases per year, with 4 million deaths per year
Measles: 20 million cases per year, with around 70,000 deaths per year
Pertusis: 16 million cases per year, with 50,000 to 200,000 deaths per year
Aspergillosis: 14 million cases per year, with 600,000 deaths per year
Meningitis: 8.7 million cases per year, with 380,000 deaths per year (10% to 15% of cases lead to brain damage)
Influenza: 3 to 5 million severe cases per year, with 650,000 deaths per year
Cryptococcosis: 958,000 cases per year, with 625,000 deaths within three months after infection
So, why is human civilization coming to a halt while going crazy with fear due to a disease that will probably cause much less damage than any single disease listed above?
