Research Paper On Influenza Virus

Influenza presents as a rapid onset of malaise, chills fever, sore throat, nonproductive cough. Common cold symptoms are a runny nose and eyes, nasal stuffiness. A less aggressive onset with the initial appearance of nasal sinus irritation and excessive nasal secretions. Flu contrasts from a common cold in that it usually has a sudden, acute onset of fever, fatigue, and aching pains in the body. It may also cause viral pneumonia.

It was a disease caused by the Variola virus both type major and minor. It was spread through means of contact such as airborne,bloodborne, and foodborne . Since it was a virus it hacked cells of the body and and reproduced in host cells giving the body terrible effects and symptoms such as permanent red scars/spots , vomiting, fever and colds. It can be tested and confirmed through the use of an electron microscope and through physical findings. . It lasts a duration of couple weeks to a month and during this time makes the person significantly ill.

Food or bacteria in the intestines, or even the lining of the bowel may cause the uncontrolled inflammation associated with Crohn 's disease. Signs and Symptoms: The symptoms of Crohn 's disease depend on where the disease occurs in the bowel and its severity. These are some symptom examples Chronic diarrhea, often bloody and containing mucus or pus Weight loss Fever Abdominal pain and tenderness Feeling of a mass or fullness in the abdomen Rectal bleeding

These viruses "drift" genetically, which is why the flu vaccine has to be tweaked from time to time. Symptoms of H1N1 swine flu are like regular flu symptoms and include fever, cough, sore throat, runny nose, body aches, headache, chills, and fatigue. Many people with swine flu have had diarrhea and vomiting. Therefore, on social media people would typically discuss their condition describing these symptoms, for example “I m suffering from fever having body aches”, “I have been vomiting since last night”. These tweet example do not surely tell that it is a swine flu outbreak, but if large number of are talking about these symptoms and have some correlation with the swine flu is may be predicted as swine flow.

1. Varicella-Zoster virus (VZV): Varicella and Zoster virus (VZV) belongs to the Alphaherpesvirinae subfamily and is the responsible for two human illnesses: varicella and zoster. Three Alphaherpesviruses are capable of infecting humans: herpes simplex virus 1 (HSV-1), herpes simplex virus 2 (HSV-2) and varicella-zoster virus (VZV). The members of this subfamily are commonly characterised by their ability to establish a latent infection in neurons. Primary infection occurs in epithelial cells leading to a skin rash and fever as a phenotype.

The illness starts as fever, general and cold. In some children and adults it starts with rash. The virus is culturable from the mononuclear cells of an infected person 5 days before the rash appears or a day or two after the rash. Spots occur on the body which starts as red itchy lump.

The 1918 influenza pandemic killed an estimated 50 million people, with some estimates as high as 100 million deaths (Taubenberger, “1918 Influenza: the Mother” 1) with at least 500 thousand of those deaths being American

It is difficult to find two patients with the same symptoms and the same patterns of disease. That complicates often it is diagnosed. The evolution of the disease develops in stages and other outbreak in which the effects of the disease forwarded. Also, there are very severe lupus and some not so serious as those that occur and are limited to skin conditions.

The measles is an air born disease spread though cough and sneezing of those infected. Symptoms include fever, cough, runny nose, and red eyes. After the symptoms you may begin to notice the forming of small white spots within the mouth and a red flat rash on the face and spreading to the rest of the body will follow. Complications could occur such as blindness, inflammation of the brain, and pneumonia. There are no specific treatments available but supportive care such as drinking plenty of fluids, maintain a healthy diet, and medications to control the fever.

Emerging influenza is a seasonal viral disease caused by influenza A virus (H1N1). It spreads rapidly and costs society a considerable amount in terms of health care expenses, reduction in productivity as well as loss of life. The World Health Organization (WHO) has declared the outbreak to be a pandemic because of growing worldwide cases [5]. It cost the society a huge amount in terms of morbidity and mortality and monetary cost as well with a typical flu pandemic. The existence of influenza virus among human population in many countries of the world including India has emphasized public health care organizations to take effective preventive measure.

The flu is one of the most commonly spread infectious diseases in the United States. Each year, between 5% and 20% of Americans will become infected with the influenza virus ("Seasonal Flu Q&A"). For the majority of those people, the symptoms associated with the flu-- fever, chills, dehydration, body aches, and vomiting-- are non life-threatening and typically only last for a couple of days. However, for people who become infected with the flu virus while being hospitalized for a different reason, the rates of serious flu-related complications are much higher. The most effective way to prevent the spread of the influenza virus is by receiving a yearly flu shot, but disappointingly, most hospitals in the United States do not require employees

But the problem is these symptoms are also observed in cold and flu. Itchiness and redness can spread around the eyes and result in swelling of eye areas. Coughing, wheezing and sneezing also fall under common mold allergies. If you have had no history of cold or flu in recent past, and you are suffering form these symptoms, it can be a case of mold exposure. To be confirmed, walk into other parts of the house, get out in the garden and go in to open air.

In a passage from The Great Influenza, author John M. Barry writes about what it is like to be a scientist. He describes scientists as pioneers and uses that to get across his idea. The author states that being a scientist is brave and uses metaphor, the motif of an explorer, and logos to prove his point. In the start of the passage, the author makes the point that to be a scientist is to be uncertain.
