What factors affect the spread of influenza?
Factors that affect the spread of the influenza center to the virus exposition in the form of aerosol. Three types of influenza spread at different pace, but all spread with cough and sneezing infected individuals. Hygienic measures such as hand washing and avoiding the proximity of sick people at the height of their infection reduces the spread of the virus. Vaccination may slow the rate of influenza infection and protect vulnerable populations.
The influenza is an infectious respiratory virus spreading by aerosol droplets emitted infected. The infection comes from direct inhalation into the lungs and exposure through the nose and mouth. The spread of influenza from one person to another may occur before infected individuals experience the symptoms of influenza, but is the worst at the height of the fever. Children spread the flu more efficiently than adults. The virus needs moisture and dries quickly if it is exposed to ultraviolet radiation or dry air, which may be the prevalence of influenza during damp and darker winter weather.
in damp droplets can the Chřus virusIPS survive outside the body for some time on things like railings, dishes and handles. Through this, it spreads by contact with the hands to the mouth when someone touches the object of the contaminated aerosol and then touches his own mouth. Sharing cups and dishes with infected individuals increase the risk of infection. For this reason, it is consistently washing hands with soap and water and properly washing dishes and dishes helps reduce the spread of flu.
The two main factors in the spread of influenza depend on the strain of the virus and its speed of mutation, because the trunks of the flu constantly mutate when they compete with the host immune system. Flu B and C are milder forms, but the flu and creates more serious cases of disease. The pandemic occurs when the virulent influenza tribe infects millions of people around the world, usually because of new mutations that migrated from other animals to humans. For exampleHo tribe related to bird flu that caused bleeding and other unusually serious symptoms.
Vaccination prevents the spread of flu in common forms, especially influenza B, but does not guarantee protection against the spread of new mutations. It is recommended for seniors who are at greater risk of serious complications. Hand washing, covering the mouth and nose during sneezing and avoiding contact with individuals at the top of their infections are important. If they suffer from the flu at home and avoid public places until recovery, it is less likely that they will expose other virus.
