How to avoid respiratory infections in winter – IndiaTimes

With a cool nip in the weather, winter is finally here. Its the time of the year for food, festivities, and even vacations and trips. "While we enjoy this season and its festivities, we cannot ignore the fact that this winter also brings with it its ugly side and hence also referred to as flu season," says Dr. Sachin D Consultant - Interventional Pulmonology Critical Care & Sleep Medicine, Fortis Hospital, Bengaluru. Respiratory infections like the common cold (Rhinitis) and Flu are very common in wither season. These infections are mostly caused by viruses although this can lead to secondary bacterial infections and pneumonia. Dr. Sachin shares valuable information on common cold, the symptoms and preventive measures for it.

Common cold presents as runny or stuffy nose, sneezing and might lead to sore throat and coughing. Symptoms usually last for a few days to a week. Flu presents as fever with chills, extreme fatigue, body ache along with cold. Symptoms may last for a few weeks. Without proper care these may cause complications like bronchitis (infection of airway causing yellow phlegm and wheezing), Pneumonia (Infection in lungs causing chest congestion and breathing difficulty), worsening of underlying medical conditions (Asthma, heart, and lung diseases), dehydration, ear and sinus problems.

Since most of these infections are caused by viruses like Rhino virus, Adeno virus, Respiratory syncytial virus, Influenza, and parainfluenza virus among others, these can be highly contagious and spread from person to person via aerosols or contact. When a person coughs or sneezes, the droplets release into the air carry viruses which get inhaled by nearby contacts leading to spread of infection. It can also spread by close contact and fomites (used handkerchiefs, towels etc.)
