Pathogenicity is the potential disease-causing capacity of pathogens, involving a combination of infectivity (pathogen's ability to infect hosts) and virulence (severity of host disease).
The period of illness is acute. Symptoms often start with vomiting followed by four to eight days of profuse diarrhoea. Dehydration is more common in rotavirus infection than in most of those caused by bacterial pathogens, and is the most common cause of death related to rotavirus infection. [71]
Norovirus, also known as Norwalk virus and sometimes referred to as the winter vomiting disease, is the most common cause of gastroenteritis. [1] [6] Infection is characterized by non-bloody diarrhea, vomiting, and stomach pain.
Clinicians often pay close attention to the patient's symptoms, family history of autoimmune diseases, and any exposure to environmental factors that might trigger an autoimmune response. The physical examination can reveal signs of inflammation or organ damage, which are common features of autoimmune disorders.
Conjunctivitis can affect one or both eyes. [1] The most common infectious causes in adults are viral, whereas in children bacterial causes predominate. [6] [3] The viral infection may occur along with other symptoms of a common cold. [1] Both viral and bacterial cases are easily spread between people. [1]
A review of systems (ROS), also called a systems enquiry or systems review, is a technique used by healthcare providers for eliciting a medical history from a patient. It is often structured as a component of an admission note covering the organ systems, with a focus upon the subjective symptoms perceived by the patient (as opposed to the objective signs perceived by the clinician).
Lars Walløe argued that these authors "take it for granted that Simond's infection model, black rat → rat flea → human, which was developed to explain the spread of plague in India, is the only way an epidemic of Yersinia pestis infection could spread". [66]
Large styes may interfere with one's vision. Eyelid cellulitis is another potential complication of eye styes, which is a generalized infection of the eyelid. Progression of a stye to a systemic infection (spreading throughout the body) is extremely rare, and only a few instances of such spread have been recorded. [11]
