a) The onset of influenza is acute, without marked prodromal
symptoms, with a rapid rise in temperature and general symptoms.
Intense headaches, mainly in the region of the forehead, eyes and
temples are characteristic. Children are irritable, sometimes apathetic;
they have sleep and appetite disturbances. Vomiting and nosebleed
are frequent. In some cases the upper respiratory tract is affected
and catarrh of the mucous membranes begins.

b) Seasonal upper respiratory catarrh is one of the most
widespread children's diseases, which occurs everywhere and affects
children of all ages, particularly frequently very young ones. The
cases increase during the cold time of the year possibly because
children stay less outdoors and therefore do not get enough fresh
air, but get greater contact with patients and carriers of bacilli.

Грипп – самая распространённая заразная болезнь, отличающаяся разнообразием проявлений и многочисленными осложнениями. Грипп передаётся от больного к здоровому и поражает и взрослых и детей в любое время года. Инкубационный период ериппа очень короткий, от нескольких часов до двух суток. Эпидемии гриппа повторяются довольно часто ( (через два-три года), но периодически они принимают огромные размеры и охватывают всё население земного шара (так называемые пандемии). В 20 веке были две такие пандемии: в 1918-19 гг. пандемия пандемия гриппа (так называемая «испанка») охватила все страны света, в результате погибло 20 млн человек. Вторая пандемия имела место в 1957 г., тогда количество заболевших во всём мире было также очень велико, но число смертных случаев было сравнительно небольшим.

Возбудителем гриппа являются вирусы. Известно несколько видов гриппозных вирусов. Вирус гриппа, находящий ся на слизистых оболочках носа, рта и глотки больного, при чихании, кашле и разговоре попадает в воздух вместе с капельками слюны или носовой слизи, т.е. заражение происходит воздушно-капельным путём. В крови людей, перенёсших грипп, вырабатываются особые вещества ( так называемые защитные тела), которые в течение некоторого срока (1 – 2 года) обуславливают иммунитет организма к новому заболеванию данным типом вируса.
