		+	Literature search is divided with regards to the factors determining or influencing the infectivity of the influenza virus.
		+
		+	== Known factors determining the infectivity of the virus ==
		+
		+	# constituents of nasal secretions (e.g. mucus present or no)
		+	# type of the surface (smooth or porous), on which the virus was deposited; smooth surface enhances virus spread
		+	# virus type
		+	# virus concentration
		+	# [[Literature:temperature \| temperature]]
		+	# [[Literature:humidity \| relative humidity (RH) ]]
		+	# exposition to light and UV
		+	# [[Literature:ph \| pH ]]
		+
		+	== Possible routes of infection ==
		+
		+	# large droplets (10-20 <math>\mu</math> in diameter)
		+	# aerosol (small droplets of diameter < 5 <math>\mu</math>; aerosols are the source of '''long-range infections'''; it seems, that aerosols are the main route of infection)
		+	# direct contact
		+
		+	Particles of diameter < 3 <math>\mu</math>
		+	<!--i jednostkowej gęstości-->
		+	basically do not settle, particles of diameter 5 <math>\mu</math> settle after ~62 min, and those of diameter 100 <math>\mu</math> settle after 10 s.
		+	There is a notion of droplet nucleous, which is a shrunken by evaporation droplet coming from a sneeze or a cough. Initially it have around 20 <math>\mu</math> diameter but it can shrink twice by evaporation. Such droplet nuclei are highly higroscopic. Most sneeze or cough droplets have diameter < 5-10 <math>\mu</math>.
		+
		+	== Factors influencing long-range infections ==
		+
		+	# concentration
		+	# infectious dose
		+	# the number of infectious particles produced
		+	# the duration of shedding by infected carrier
		+	# the stability of the carrier in the environment
