In the middle week of Aug, the average number of flu (H1N1) patients per hospital was 1.69 (1.00 or >1.00 suggests epidemic), demonstrating epidemic, exceeding the number to be about 110,000. According to August report, 3 fatalities were confirmed from H1N1. 1.00 case/week has been reported by the hospitals of 44 districts in Japan excluding Hokkaido island.
It is obligatory to use facemask in the densely populated area especially in outside and during traveling. Japan already started vaccination from middle of Oct after observing any adverse effects of vaccines; however, initially H1N1 vaccine has been reported mild headache after initial stage of vaccination in the trial and local redness at the site of injection. The winter season should be peak to spread this flu in Japan and as well other Asian countries, so special precautions must be taken.
