Influenza (H1N1) is a respiratory illness that is caused by the influenza virus. The influenza virus is present throughout the year but is activity peaks during the winter months, though it can affect an individual all through the year. H1N1 in pregnancy needs a lot of attention and care.
Influenza (flu) virus is contagious and can spread from one patient to another. It usually spreads by the droplets which are made when the patient with flu coughs sneezes or talks. Patients with flu are most contagious in the first three to four days of their illness but they may transmit the infection even before the symptoms develop.
Symptoms usually begin two days after the virus enters the body. Patients who suffer from flu can have mild to moderate to severe disease.
Common symptoms of H1N1:
- Fever
- Cough

- Body Aches
- Headache
- Chills
- Fatigue
Children below 5 years of age, pregnant women, adults above the age of 65 and immunocompromised individuals and patients with other chronic diseases are particularly at higher risk of getting influenza.
In mild disease, patients do not need any medical care and antiviral drugs and will usually recover in 7 to 10 days. Influenza can get severe in some cases and will require medical attention, antiviral drugs and occasionally hospitalization. It can lead to complications like pneumonia, bronchitis, aggravation of asthma, sinusitis, and superimposed bacterial infections which will require antibacterial medication.
