Symptoms of Flu

Flu has the following symptoms:

  • Watery eyes 
  • Runny nose
  • Headache
  • Muscle aches
  • Fatigue 
  • Fever
  • Cough 
  • Feeling cold 
  • Sweats
  • Stuffed nostrils

Causes of Flu

Flu is caused by influenza viruses. Anybody who gets affected can transmit the infection to others by coughing, sneezing, and by touching with infected hands. These viruses can also be contracted from surfaces and crockery used by the patient. These viruses keep changing and new strains develop regularly that are different from existing ones. This is why the flu vaccine doesn't offer 100% safety from flu. If you had flu your body becomes immune to that very strain but you can catch flu again due to a different virus.

Risk Factors of Flu

A risk factor of flu is greater for children, elderly, and people with a compromised immune system. It is also more pronounced for school going children, those attending daycare, and other people in close contact with the community. Congested living spaces, lack of hygienic practices and improper handwashing also increase the risk of catching the flu.

Preventive Measures of Flu

The flu vaccine is the only measure that can be taken to prevent the flu. Other than that staying away from infected people, and observing strict hygiene practices can also help to prevent the flu.
