Respiratory Infections Overview

Upper respiratory tract infection caused by Rhinoviruses.

Rhinitis is mainly caused by human Rhinoviruses, often spread through contact.

Typical symptoms include nasal discharge, sneezing, cough, malaise, and pharyngeal discomfort without fever.

No aspirin, vaccines, antiviral medications, or antibiotics recommended for rhinitis.

Can lead to acute otitis media and sinusitis; higher incidence in children.

Rhinitis symptoms typically resolve on their own without treatment.

Rhinitis commonly peaks in children, especially during seasonal changes.

A condition characterized by subglottic edema causing a cough like a seal, hoarseness, and stridor.

A virus causing respiratory infections, especially severe in premature infants and young children.

Inflammation of the bronchioles, often caused by RSV, leading to wheezing and respiratory distress.

A high-pitched, wheezing sound during breathing due to airway obstruction or narrowing.

Inflammation of the bronchial tubes, which may not indicate a lower respiratory tract infection.

A type of pneumonia caused by extracellular bacteria leading to fluid buildup in alveoli, characterized by sudden onset and acute symptoms.

The initial symptoms that signal the onset of a disease, like a warning signal.

Difficulty or labored breathing, often a symptom of respiratory issues.

Pneumonia caused by intracellular bacteria like Mycoplasma, often presents mild symptoms and is not well treated with penicillin.

An abnormally fast heart rate, which can accompany respiratory distress.

Often caused by anaerobic bacteria, takes weeks to develop with night sweats and weight loss, characterized by cavitary lesions on X-ray.

A condition where the lungs become overly expanded, often seen in severe respiratory illnesses.

A Gram-negative bacterium causing severe pneumonia mostly in immunocompromised individuals, transmitted via inhalation from contaminated water sources.

Signs and symptoms that present during the course of a disease, helping identify the condition.

A Gram-positive bacterium, often implicated in a range of infections including pneumonia due to its capability to form abscesses.

A condition with thick, yellow or green nasal discharge, often associated with bacterial infections.

A sinus infection caused by viruses, often characterized by clear rhinorrhea and headache.

A sinus infection resulting from bacteria, typically causing purulent discharge and facial pain.

A common symptom of sinusitis caused by inflammation in the sinuses affecting nearby areas.

Pain or discomfort when pressure is applied to the sinuses, indicating inflammation.

Swelling around the eyes, often seen in sinusitis due to fluid accumulation.

Enlargement of lymphoid tissues, indicating an immune response to infection or inflammation.

A throat infection caused by viruses, typically self-limiting with symptoms like sore throat and fever.

A type of bacteria that can cause pharyngitis and other infections, requiring quick diagnosis and treatment.

The act of breathing in aerosols or particles, which can affect health.

Health issues caused by medical treatment or care.

When a person's health is weakened, making them more susceptible to infection.

Cells with tiny hair-like structures that help clear mucus and debris from airways.

Prevention of the body's natural cough reflex, which can lead to complications.

Microorganisms that cause pneumonia, including bacteria and viruses.

Tiny liquid droplets suspended in the air, which can carry viral infections.

Bacteria that can cause a severe form of pneumonia known as Legionnaires' disease.

The automatic response that clears the throat and airways, essential for preventing choking.

A type of bacteria that is typically resistant to antibiotics; often found in infections.
