what you know about cause of flu and how its spread
Answers
Answer:
Flu is a infectious air-borne disease which affects the lungs. It was spread from animals to humans. In this disease, the person affected gets dry coughs, breathlessness, difficulty in breathing, etc. This is spread through air, in exactly the same way as Covid-19 virus. It can also spread by having contact with the infected person, or by using his articles.
Answer:
Influenza or flu is caused by a virus that leads to respiratory illness. It is highly contagious and spreads easily through coughs and sneezes of an infected person.
Influenza can be communicated simply through touch. Adults can start spreading the virus 2 days before the symptoms start showing up and they can spread it for up to 7 days from the day they become ill. This means that you can end up spreading the influenza virus way before you figure out that you are ill.
It is observed that 250,000 - 500,000 people die due to influenza in a calendar year. In countries with heavy industrialization, deaths caused due to influenza are reported to be higher in people aged above 65.
An influenza epidemic can go on for several weeks when a large part of the population in one country is affected by the flu.
