Flu Influenza

Flu or influenza is also known as seasonal flu and it is a respiratory disease. It is highly contagious and it is different from cold.

Types

Here are three types of influenza virus:

  • Influenza A
  • Influenza B
  • Influenza C

Influenza A and B cause seasonal flu and they occur seasonally in the environment. Influenza C causes mild respiratory illness and is not as a result of seasonal outbreaks.

Symptoms

The symptoms of both the flu and cold are more or less the same. They include a blocked or runny nose, sore throat and cough. But flu can be deadly and its treatment MUST be taken and should not be taken for granted. Below are some of the symptoms of flu which differentiates it from cold:

  • High temperature
  • Headache
  • Pain in joints and limbs
  • Cold sweats
  • Shivering
  • Fatigue
  • Exhaustion
  • Nausea
  • Vomiting

It is quite possible that you face one of the above symptoms in flu.

  • Avoid contact with people whenever it is a possibility
  • Keep warm and rest
