Is generally believed that a cold main mode of transmission is through droplets in the air dissemination. In recent years, some scholars abroad through experimental studies suggest that influenza is not entirely through the air-borne, and mainly through the hands and the hands of direct contact, at least by the rhinovirus and respiratory syncytial virus is so cold.
In the United States弗尼吉亚State University Professor Jan has done three possible spread of influenza experiments: ① a cold virus donor and receptor under the same room 72 hours, and put a fence between the two, to prevent inter-hand contact with the hand in order to observe the small particles of the spread of aerosol; ② will be cold for the body with several receptor sitting on a small table, so that donor coughing, sneezing and talking at the time of the respiratory tract secretions sprayed receptors in order to observe the spread of aerosol particles; ③ to cold donor respiratory secretions pollution on our hands, and then contact receptor's hand, let receptors in their own hands have been contaminated contact nose and eyes, to observe the situation in direct contact. The experimental results are: 10 small aerosol particles of the receptor is not a case of cold; 12 large aerosol particles, only 1 receptors were cold; and 15 hands in direct contact with the receptor, there 11 were suffering from a cold. It can be speculated: direct contact with flu pathogen is an important means of dissemination.

Why would a cold stream when some of the nose and sputum?
Why would a cold stream when some of the nose and sputum?
Cold is the most common harassment of people's disease, influenza, the respiratory tract be some runny nose and phlegm, which makes people feel uncomfortable, in fact, the nose and sputum is not necessarily a bad thing. Is because a cold accompanied by inflammation of the respiratory tract will produce some viruses, bacteria, necrotic cells, such as waste, sputum and nose function is to help remove these "undesirable waste." And spicy food will cause increased respiratory secretions, when we run into the respiratory tract for more than substance, it will secrete some sticky things around them, and to strengthen the surface of respiratory cilia movement in order to discharge foreign body. Or mucus from the nose to help cure a cold.

Cold medicine in the title in the end what diseases
Under normal circumstances the clinical manifestations of influenza恶寒fever, headache, body aches, nasal sound of heavy, sneeze runny nose, such as pulmonary vein floating Wei symptoms, or accompanied by coughing, pharyngodynia,等症hoarseness. When the line flu pandemic is a wide range of symptoms similar to men, women and children in order to急起fever, headache, body aches weak and have less lung Wei symptoms. However, in a cold throughout the course of disease may vary from person to person because of the time varies from place to place, and the righteous have actual situation, there is evil and folder, so its performance can not be generalized.
Differentiation Typing 【】
1, cold cold
Stuffy nose, heavy sound, nose itching, sneezing, runny-ching T, itchy throat, cough, sputum清稀, mouth不渴, or thirsty hi hot, fever恶寒, cold re-hot light, no sweat, physical pain, the pulse floating or floating tight, thin white moss.
2,风热感冒
恶寒fever, cold light TGA, or sweat, headache or faint bulge,面赤lipstick, dry mouth, micro-渴欲drink, dry throat pain, cough, thick yellow sputum, cough poor spit, chest tightness, flow Turbidimetry T pulse floating tight, thin yellow moss.
Chinese medicine is that the flu in humans under conditions of less than righteous, rehabilitation sense of wind, cold, heat, wet, dry, fire (temperature, heat), or the evil result of疫毒a exopathic disease.
The disease can occur throughout the year, but winter and spring for more. Natural course of disease for 3 ~ 7 days. Throughout the course of the few mass change. Generally occur sporadically, if serious illness, in a period of widespread, men, women and children are likely to occur.

The cold weather forecast said the meaning of index and how to use the
In addition to the occurrence of influenza and bacterial infection, the weather conditions is an important factor. Beijing professional meteorological station launched in accordance with changes in the weather and the people live, work closely related to influenza index forecasting, as it and the weather forecast every day through the media to the general public notice on the second day of cold weather occurred in the impact strength. With it, the citizens, especially children, the elderly and other people can be prone to weather concerns at the same time, cold index used to determine changes in clothing and activities. They will be divided into three cold index: a low-fat period is two-prone period of three is a high-fat period. Cold index level and weather changes are mapped, there are strong cold air intrusion, Beijing temperature or the temperature suddenly dropped dramatically rapid spurt may cause or have a cold, so this period is a high rate. On the other hand, the temperature has not fluctuated, the weather in a stable state for low-fat period.
Cold index prompted expressions
Index Name Index sunny breeze Yam snow (rain) days of high winds, cool days of warmer weather
Cold
1 to enhance cold exercise early in the evening to adapt to changes in temperature difference. Outdoor activities should be added to clothing, because the wet winter cold air easily. Cool down marginally, due attention to warm to prevent cold. Indoor and outdoor temperature difference less suitable ventilation windows, so that more fresh air room.
2 sooner or later go out for a walk at noon sun. Outdoor activities should not be too long and not easy to go out to patients. People feel cold, according to promptly increase the cold clothes. Suitable for indoor and outdoor air circulation, subject to the physical condition of the ventilation time to master.
3 healthy people to enhance awareness of the prevention of influenza, the patient will pay attention to the combination of therapy and exercise. Patients with the best meals to reduce activity, cold weather will add to the illness. Do not go out to patients to prevent the cold, even worse. Illness can appropriate the sun, riding on a good day for an early resumption of health.

Features of diseases of children will have repeated the phenomenon of cold
Features of diseases of children will have repeated the phenomenon of cold
Under normal circumstances, colds, sinusitis, otitis media, sweating, enuresis, snoring, asthma, constipation, headaches are common symptoms of pediatric clinical reporter recently informed that the disease can cause severe nose flat nose and development well, from the widened eyes, mouth breathing, facial expressions sluggish, showing a special "adenoid face." Under normal circumstances, children 2-10 years of age is adenoidal period, the 6-year-old to the maximum length of time, after 10-year-old began to shrink, to 13-year-old disappeared. When the upper respiratory tract infection, the adenoids can increase inflammation. In childhood, repeated upper respiratory tract infections, chronic rhinitis, allergic asthma and other factors could lead to chronic inflammation of the adenoids, the occurrence of hyperplasia mast.
Adenoidectomy acute inflammation of the health hazards of children is not very big, but adenoidectomy repeated stimulation due to inflammation caused pathological hyperplasia, hypertrophy, then the impact on children's growth and development, and even affect the general development of children and nutrition.
Under normal circumstances, adenoid hyperplasia general can not easily be directly detected, children with symptoms of mild to normal activities during the day, parents are also very easy to overlook, this is adenoid hypertrophy in children than the prevailing reason that when a child repeatedly cold When parents do not just look at a cold, do not forget to bring their facial features to be checked.

The human body in the cold after the immunity may be how long?
The human body in the cold after the immunity may be how long?
Usually the body's cold caused by the influenza virus, the virus enters the human body, the body's immune system will make the appropriate response to resistance, this resistance is the immune response. After a cold immunity, the general could be maintained for about a month time, influenza may be the maintenance of 8 ~ 12 months. Although the post-cold machine experience have immunity, but can cause flu-type virus in many species, often in a cure for HIV infection, shortly after another occurred infection. Therefore, a person may be repeated in a short time the phenomenon of cold.
