Influenza

What is seasonal influenza?

Every winter, the population in the northern hemisphere is affected by influenza outbreaks. This is called seasonal influenza. Two types of influenza virus, types A and B, are the cause of these outbreaks. As these different viruses are constantly mutating, the immunity we gained from previous exposure is gradually outdated.

The timing and size of the outbreak varies widely between the different winter seasons and depends on the immunity in the population. In years with larger epidemics, 10 to 30 per cent of the Norwegian population may be infected. Outbreaks usually start around Christmas/New Year and last for about 12 weeks. The peak in recent seasons has fallen around New Year or early February. However, this can vary between seasons.

Estimates made in Norway in the period suggest that about deaths a year are caused by influenza. However, this is only an average and can vary greatly from year to year. The people who die are most often elderly and or have chronic underlying diseases.

    • Grip (Influenca) je akutna, infektivna, veoma kontagiozna bolest uzrokovana virusima influence u kojoj u početku dominiraju simptomi toksemije u vidu tempe¬rature, intenzivne glavobolje, bolova u mišićima i zglobovima, anoreksije, povraćanja, dok se respiratorni simptomi kao što su kijavica, gušobolja, kašalj, javljaju kasnije.

    Kontagioznost i virulencija ovih virusa dovode do pojave oboljenja u epi¬demijama i pandemijama. Masovnost oboljevanja praćena komplikaci-jama i visokom smrtnošću učinili su da se epidemije istorijski pamte kao najveće pošasti čovečanstva. Svakako najteža pandemija gripa bila je godine (&#;španska groznica&#;) kada se računa da je obolelo oko miliona a umrlo preko 20 miliona ljudi. U pandemiji godine (&#;azijski grip&#;) obolelo je 70 miliona ljudi. Takođe je velika pandemija gripa bila (&#;hongkonški grip&#;).
