An epidemic viral infectious disease characterized by acute nasal catarrh, or by inflammation of the throat or the bronchi, and usually accompanied by fever and general weakness; also called grippe. It is caused by several forms of RNA virus which mutate readily and thereby render vaccines prepared against older forms ineffective, often requiring a new form of vaccine for each new outbreak.
an acute infectious viral disease characterized by fever, muscle aches, and respiratory tract and gastrointestinal tract symptoms.
Common, contagious respiratory infection caused by a virus. Incubation after exposure is 24 to 48 hours.
Symptoms include sneezing, discharge of fluid from the eyes, loss of appetite, fever, ulcers, on tongue, drooling, and apathy. If properly treated, the cat should be cured in a week or ten days, but if neglected influenza may open the way for serious viral disease. Even a simple cold is reason enough to keep a cat in a warm place, well protected from dampness and drafts.
a viral infection characterized by headaches, muscle aches, fever, weakness, and cough; commonly called the "flu"
A viral infection of the respiratory tract; also known as the flu.
Infectious disease. You can have a vaccination against flu if you are having chemotherapy.
an acute febrile highly contagious viral disease
a disease caused by a member of the Orthomyxoviridae
a highly contagious illness caused by a virus
a respiratory infection caused by a family of flu viruses
a viral infection that has a relatively short lifespan and causes problems for its victim in the form of several minor effects (chills, high fever, aches and pains, headaches, sore throat, mucosal irritation)
Contagious infection, usually of the lungs, caused by a virus and transmitted through airborne particles. Also called the flu. Children who have influenza should not be given aspirin because its use has been associated with Reye's Syndrome.
more commonly the "flu", is transmitted from the sneeze or cough of an infected person, person to person contact, or contact with objects that an infected person has contaminated with nose and throat secretions. The symptoms are fever, headache, chills, fatigue, muscle aches and pains, runny nose, sore throat, and hacking coughs. "Flu shots" have been developed, but some people are adversely affected by it. Good hygiene and sanitary measures are an effective means of prevention. People who do suffer from the virus are advised to drink plenty of fluids, bedrest, and over-the -counter medicines may lessen the intensity of the disease. Influenza epidemics, such as the Spanish influenza of 1918, can result in massive devastation.
A highly contagious, acute respiratory infection of the nose, throat, bronchial tubes, and lungs caused by the influenza virus. It is responsible for severe and potentially fatal clinical illness of epidemic and pandemic proportions.
A serious respiratory infection caused by the influenza virus. For more information on Influenza in pregnancy see the Womenâ€™s Hospital Website on Influenza in and Around Pregnancy as well as the Website on Influenza and Your Baby.
Highly contagious respiratory disease caused by many different viruses. Vaccines are available for some of them. Treatment is for the secondary infections.
An acute viral infection involving the respiratory tract, occuring an isolated cases in epidemics.
A serious disease caused by viruses that infect the respiratory tract.
commonly referred to as the flu, is a virus that attacks the respiratory tract, causing (among other symptoms) fever, headache, extreme fatigue, dry cough, sore throat, nasal congestion, sneezing, irritated eyes, body aches and extreme coldness. Influenza's effects are much more severe and last longer than those of the cold, and recovery often takes about one to two weeks. It can be deadly, especially for the weak, old or chronically ill.
A contagious viral infection of the nose, throat and lungs
the flu; an infectious respiratory disease contracted by inhaling a virus. Influenza is characterized by chills, fever, prostration, headache, muscle aches, sore throat and a dry cough. Influenza may be life-threatening in infants, the elderly and persons with compromised immune systems.
The flu is caused by viruses that infect the respiratory tract which are divided into three types, designated A, B, and C. Most people who get the flu recover completely in 1 to 2 weeks, but some people develop serious and potentially life-threatening medical complications, such as pneumonia. Much of the illness and death caused by influenza can be prevented by annual influenza vaccination.
an infectious illness, caused by a virus, which can seriously affect the breathing. It is usually known as flu.
A highly contagious disease caused by various types of virus; characterized by sudden onset, fever, exhaustion, severe aches and pains, and increasing inflammation of the respiratory mucous membrane.
An infectious disease caused by a virus that affects the respiratory system, causing fever, congestion, muscle aches, and headaches.
Highly contagious viral infection of the nose, throat, and lungs. Commonly known as the flu, this seasonal disease can be fatal to the aged, immunocompromised, and infants. (pink book chapter on influenza) (view photo)
Acute viral infection of the respiratory tract caused by one of three strains of influenza virus (A, B, and C).

A contagious and infectious respiratory illness usually occurring in the winter.
Commonly called the flu , influenza is a virus that infects the respiratory tract and may cause fever, headache, and general body aches, runny nose, sore throat, or cough.
Influenza, commonly known as the flu, is an infectious disease of birds and mammals caused by an RNA virus of the family Orthomyxoviridae (the influenza viruses). In humans, common symptoms of influenza infection are fever, nausea, vomiting, sore throat, muscle pains, severe headache, coughing, and weakness and fatigue. In more serious cases, influenza causes pneumonia, which can be fatal, particularly in young children and the elderly.
