droppings on
a bench in the winter park
flu virus contained in? (hisashi)

I wrote this with thought of a biologist. It then remided me of Basho's January haiku, "uguisu ya mochi ni fun suru en no saki" (onto a drying rice cake / on the open veranda / a bush warbler dungs). This Basho's one was followed by Shiko's wakiku, "hi mo massugu ni hiru no atataka" (sunlight, also straight / warm daytime). Shiko's wakiku can be followed after mine and we also expect the sunlight UV will kill the virus(s). Do you agree?
