First, some basics about colds and flu. Both are viral respiratory infection affecting the nose, throat and lungs. Colds are caused by more than 200 different viruses (including types and subtypes), while seasonal influenza ( flu subtypes A, B and C ) the lead a few virus strains that result in local outbreaks each year. In general, the periods of highest incidence of colds are autumn and winter, flu season usually is in winter. It is easy to confuse a cold with flu, as they often have similar symptoms.
A comparison (see box on next page): cold can start gradually, and usually lasts seven days, although it may take up to 10 days to go away . The flu can begin suddenly and make you sick in a moment. Other symptoms besides those listed, may include loss of appetite, nausea, vomiting, diarrhea, otitis media and abdominal pain. The fever may last up to three days, but you may feel weak and tired for a week or two.
Reduce the risk
Forget what your mother said about you was sick because you went out with wet hair or without a jacket, because neither the cold or the flu come for that, but according to Dr. Marco Antonio Figueroa, otolaryngologist, ” We have specialized cells to sweep all infectious agents that come in contact with our body. In cold weather these cells do not function the same, and the elimination of microorganisms is slower, which favors infection appear. “So it is worth taking precautions during cold weather season.
Colds and flu viruses come from that spread through droplets that travel through the air, person to person, each time an infected person sneezes or coughs. Viruses can also spread by touching an infected surface, such as a chair or a hand and then touching your nose, mouth or eyes.
On average, children get colds from six to eight times a year, and adults one to four times. It is expected that one in ten people get the flu this winter in Spain. The best defense is good hygiene. This means washing your hands frequently, use hand sanitizers are alcohol based, disinfect shared surfaces and avoid touching your eyes, nose and mouth.
Although most people recover from the flu, about 8,000 people die each year in Spain for seasonal flu or complications of chronic diseases caused by flu. To prevent flu, especially in people who are at high risk groups, one option is the vaccine that is recommended after six months. In healthy adults, it can prevent infection after the first dose. October and November are the best months, and vaccination is needed annually to achieve optimum protection, since strains of influenza virus change from year to year.
Guide to surviving the symptoms
Drugs banish non prescription cold viruses or the flu, but can help relieve common symptoms. According to Dr. Figueroa, combinations of decongestants and analgesics can be effective. “It is a common practice, but it is known that antiviral drugs can reduce the number of days of the condition,” he says.
Read labels carefully and check with your pharmacist or doctor when taking these medicines, to be sure there are no known drug interactions controlled you are taking, or will be counterproductive to your daily work. A side effect of antivirals can be fatigue.
” Most of these prescription medicines among its ingredients include antihistamines , which usually cause very sleepy or tired. This is not recommended for people who drive vehicles or operate machinery, “says Dr. Figueroa.
So what helps?
Antibiotics do not, they do not work with viruses. Some people have much faith in vitamin C, but research on its effectiveness are inconclusive. Save rest, as fatigue can prolong symptoms and go to the kitchen rather than the pharmacy.
Take plenty of fluids (8 to 12 glasses of water, tea or juice). Influenza tends to cause dehydration, so it is recommended to take one liter of normal daily consumption. In addition, it helps to have a more fluid secretions.
For sore throat, gargle with astringent solutions (salt or baking soda with hot water) to remove the microorganisms in the mouth and soothe the pain, or with lemon and honey, which help thin mucus. It is also helpful to moisten the air with a vaporizer (cool or warm mist).
In the case of children, the best option is to let the disease run its course. “Usually these are self-limiting viral processes, so that measures such as controlling the temperature, if necessary-a diet rich in fluids and maintain the nutritional status, are more than enough,” said Dr. Alfredo Morayta.
