how does upper respiratory infection start?
433664
For an upper respiratory infection (URI) to occur, a virus enters the body, usually through the mouth or nose. A person may transmit it through touch, or by sneezing and coughing. Any place where people gather in an enclosed space, such as a classroom, office, or home, can be a high-risk area for the spread of URIs.

How does a cat get an upper respiratory infection? The main viruses and bacteria that cause URI in cats are highly contagious. An infected cat will shed contagious particles in saliva or secretions from the nose or eyes.

Sneezing is a common symptom of upper respiratory infections (URIs) in cats. Often referred to as the “common cold” or the “cat flu”, upper respiratory infections can be viral, bacterial and even fungal, although that's less common.

Often, pneumonia begins after an upper respiratory tract infection (an infection of the nose and throat), with symptoms starting after 2 or 3 days of a cold or sore throat. It then moves to the lungs.

Types of upper respiratory infection include the common cold (head cold), the mild flu, tonsillitis, laryngitis, and sinus infection. Of the upper respiratory infection symptoms, the most common is a cough. Lung infections may also lead to a stuffy or runny nose, sore throat, sneezing, achy muscles, and headache.

The causes of URIs are almost always viral. Droplets of infected saliva and mucus spray out into the air when a person sneezes or coughs. Other people may breathe them in, or they can land on surfaces that others touch. If another person then puts their hand near their mouth, they may get an infection.

If they have roseola, young children who are typically 6 to 36 months old can develop symptoms of an upper respiratory virus, such as a cough, congestion, and high fever, which are then followed by a rash.

Your upper respiratory tract includes the nose, throat, pharynx, larynx, and bronchi. Without a doubt, the common cold is the most well-known URI. Other types of URIs include sinusitis, pharyngitis, epiglottitis, and tracheobronchitis.

How can acute upper respiratory infections be prevented? The best protection against URIs is frequent handwashing with soap and water. Washing your hands reduces exposure to secretions that can spread infection.

A runny nose, nasal congestion, sneezing, cough, and mucus production are the hallmark symptoms of URIs. Symptoms are caused by inflammation of the mucous membranes in the upper respiratory tract. Other symptoms include: fever.

The upper respiratory tract includes the mouth, nose, sinus, throat, larynx (voice box), and trachea (windpipe). Upper respiratory infections are often referred to as "colds." The lower respiratory tract includes the bronchial tubes and the lungs. Bronchitis and pneumonia are infections of the lower respiratory tract.

A cold is a viral upper respiratory tract infection that typically affects the nasal part of the respiratory system. The infection is usually mild and goes away without treatment. Symptoms may include a runny nose, headache, and sneezing. About half of patients can also experience a cough or sore throat.

Bacteria or viruses in the middle ear cause ear infections. A person who has, or had, an upper respiratory infection may also develop an ear infection. Ear infections are not contagious. However, the respiratory infections that might accompany an ear infection are.

Upper vs. Lower respiratory tract infections differ from upper respiratory tract infections by the area of the respiratory tract they affect. While lower respiratory tract infections involve the airways below the larynx, upper respiratory tract infections occur in the structures in the larynx or above.

Upper vs. While lower respiratory tract infections involve the airways below the larynx, upper respiratory tract infections occur in the structures in the larynx or above. People who have lower respiratory tract infections will experience coughing as the primary symptom.

A: In general, most feline upper respiratory infections are caused by viruses that are specific to cats. These viruses are not contagious to other species, including dogs and people.

The postnasal drip of a common cold can cause mild, non-productive coughing, which signals an upper respiratory tract infection. But the cold virus does not infect the lungs, themselves, so coughing with a cold is almost always due to congestion in the throat, not the airways.
