Contact route, Body. It depends on two major categories: 1. How you get it: direct contact, respiratory contacts and how close you are to source i.E school, family member. 2. How strong you are: age is a major factor, neonates, infants and elderly are at the highest risk, also immunosuppressed patients can be the most susceptible ones. Why more in cold weather? People more indoor, schools are open, low humidity.
Children and family. Children in daycare, and starting in new school often spread respiratory germs (bacteria and viruses) to each other, and then bring the germs home to their families.
Yes. The most common cause of the common cold, sore throat, sinus infection, bronchitis or even many ear infections are cold viruses. But also bacteria such as strep, staph, hemophilus, pneumococcus, moraxella, can cause all the same diseases.
Yes. Rhinitis, nasopharyngitis or the common cold, pharyngitis, rhinosinusitis or sinusitis, and laryngitis can be caused by viral infections. Most common viruses: rhinovirus, respiratory syncytial virus, parainfluenza virus, influenza virus, coronavirus, and coxsackievirus.
What is more serious of a disease, lower respiratory tract infections or upper respiratory tract infections?
Lower respiratory. Upper respiratory infections involve upper airways such as throat, nasal cavity, paranasal sinuses, eustachian tubes, trachea as, nd bronchi. When the disease process in the bronchi, or bronchitis, continues, it could begin to involve lower airways in the lung tissues, which is then more advanced lower respiratory infections or pneumonia.
Lower. Upper respiratory tract infections are colds, rhinitis, pharyngitis, sinusitis and are usually caused by viruses although can also be caused by various bacteria. Lower respiratory infections are bronchitis and pneumonia also caused by viruses but more than uri's are caused by bacteria and can be more severe and even life threatening.
Why is viral upper respiratory tract infections usually benign and that of lower respiratory severe? Explanations please?
Different causes. The upper respiratory tract (nose, throat, upper airways) are usually infected by viruses. While annoying, these viruses can be cleared by our immune systems without much problem. The lower respiratory tract (bronchioles and air sacs of the lung) are more susceptible to more serious bacterial infections. These often require antibiotics to clear the infection.
Chronic lung disease. Anyone with chronic lung disease, such as asthma, smokers, those with immune problems, and elderly people, are more at risk.
Patient and source. Those who are more in contact with the source, people with baseline lung problems such as asthma, copd, immunocompromised individuals, and elderly, or very young.
Yes. All the same viruses that can cause the common cold, as well as others, (influenza virus, measles, etc.) can cause lowere respiratory infection (bronchitis and pneumonia).
Yes. Certain viruses are the common causes of lower respiratory tract infection: respiratory syncytial virus, influenza, parainfluenza, adenovirus, and human metapneumovirus, also with some attention to rhinoviruses and some new viruses (human coronaviruses and bocavirus).
Symptoms. Chronic bronchitis would be one possibility.
Infection. Infection of either the upper respiratory tract (nose and throat) or lower respiratory tract (trachea and lungs). Usually caused by either viruses or bacteria, though fungal can cause infections in immunocompromised patients.
See below. An infection of the upper or lower respiratory tract. Upper respiratory tract infections include the common cold, laryngitis, pharyngitis, tonsillitis, sinusitis and otitis media. Lower respiratory tract infections include bronchitis, bronchiolitis, tracheitis and pneumonia. These infections can be caused by a virus, bacteria or fungus.
