Cold and flu season

This last week of November I experienced some weather changes. There was no rain for the past weeks and then suddenly the weather got cold and colder now. I have observed that many people even my officemates suffered from colds and flu. Symptoms are cough, sore throat, runny nose, and nasal congestion; sometimes this may be accompanied by conjunctivitis (pink eye), muscle aches, fatigue, headaches, shivering, and loss of appetite. Fever is often present thus creating a symptom picture which overlaps with influenza. The symptoms of influenza however are usually more severe. The common cold usually resolves spontaneously in 7 to 10 days, but some symptoms can last for up to three weeks. In children the cough lasts for more than 10 days in 35–40% and continue for more than 25 days in 10%.Those suffering from colds often report a sensation of chilliness even though the cold is not generally accompanied by fever, and although chills are generally associated with fever, the sensation may not always be caused by actual fever. In one study, 60% of those suffering from a sore throat and upper respiratory tract infection reported headaches, often due to nasal congestion. This weather condition would likely to continue until Christmas so better take extra care of ourselves.
