Swine Influenza (swine flu) is a respiratory disease of pigs caused by type A influenza virus that regularly causes outbreaks of influenza in pigs. Swine flu viruses cause high levels of illness and low death rates in pigs. Swine influenza viruses may circulate among swine throughout the year, but most outbreaks occur during the late fall and winter months similar to outbreaks in humans.
The 2009 flu outbreak in humans is due to a new strain of influenza A virus subtype H1N1 that derives in part from human influenza, avian influenza, and two separate strains of swine influenza. The origins of this new strain are unknown. It passes with apparent ease from human to human, an ability attributed to an as-yet unidentified mutation. The strain in most cases causes only mild symptoms and the infected person makes a full recovery without requiring medical attention and without the use of antiviral medicines.
Swine Flu / H1N1 Influenza Symptoms
The symptoms of swine flu in people are expected to be similar to the symptoms of regular human seasonal influenza and include fever, lethargy, lack of appetite and coughing. Some people with swine flu also have reported runny nose, sore throat, nausea, vomiting and diarrhea. Symptoms of Swine flu may include all or some of the following:
• Fever
• Muscle aches
• Lethargy
• Coughing
• Headache
• Sore throat
• Runny nose
• Nausea
• Vomiting
• Diarrhea
• Lack of appetite
Complications Of Swine Influenza
Those at higher risk of catching influenza in general include those with the following:
• Age of 65 years or older
• Chronic health problems (such as asthma, diabetes, heart disease)
• Pregnant women
• Young children
But the past epidemics and pandemics of flu have shown that during pandemics most people who succumb are healthy young adults.
Complications of Swine Flu can include:
• Pneumonia
•Bronchitis
• Sinus infections
• Ear infections
• Death
Transmission of Swine Flu (How does Swine Flu spread?)
As with other flu like illnesses, Swine influenza is spread as follows:
• Coughing
• Sneezing
• Kissing
• Touching infected objects
• Touching nose, mouth and/or eyes with infected hands
• Swine flu does not spread by eating pork.
Treatment of Swine Flu / H1N1 Influenza
Swine Flu Vaccination / Swine Flu Shot
The protective ability of influenza vaccines depends primarily on the closeness of the match between the vaccine virus and the epidemic virus, so the presence of non reactive H3N2 SIV variants suggests that current commercial vaccines might not effectively protect pigs from infection with a majority of H3N2 viruses. The current vaccine against the seasonal influenza strain H1N1 is thought unlikely to provide protection. The director of CDC’s National Center for Immunization and Respiratory Diseases said that the United States’ cases were found to be made up of genetic elements from four different flu viruses—North American swine influenza, North American avian influenza, human influenza A virus subtype H1N1, and swine influenza virus typically found in Asia and Europe.
What You Can Do to Prevent H1N1 Influenza / Swine Flu?
There are everyday actions people can take to stay healthy.
• Cover your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it.
• Wash your hands often with soap and water, especially after you cough or sneeze. Alcohol-based hands cleaners are also effective.
• Avoid touching your eyes, nose or mouth. Germs spread that way.
• Try to avoid close contact with sick people.
• Influenza is thought to spread mainly person-to-person through coughing or sneezing of infected people.
• If you get sick, CDC recommends that you stay home from work or school and limit contact with others to keep from infecting them.
Above all. Don’t get stressed by the fear of getting the swine flu. Stress can undermine your immune system. The flu doesn’t kill everyone and in most cases may prove benign. Mild exercise, meditation or yoga and healthy nutritious diet can help keep your immune system in good condition and able to ward of any infections. Not every ‘infection’ becomes a full blown ‘disease’. Most infections are taken care of by your body even before you know that you were infected. Most infections affect gravely those people who are vitally deranged. So instead of panicking about the flu, stay calm and focus on becoming a healthy ‘you’.
Influenza is characterised by fever, myalgia, headache and pharyngitis. In addition there may be cough and in severe cases, prostration. There is usually not coryza (runny nose) which characterises common cold infections.
Sign and Symptoms of Chicken Pox
Typically, chicken pox begins with a low fever, headache, rash, and a general feeling of sickness, or malaise. The rash, which usually covers the face, scalp, and trunk of the body, starts as red bumps but quickly develops into small blisters. The rash and the blisters are extremely itchy. As the disease progresses, the blisters break open and form scabs, which fall off after about one to two weeks. The incubation period—the time between initial infection and the first appearance of symptoms—is approximately two weeks.
Sign and Symptoms of Chikungunya
The primary symptoms of Chikungunya include –
• Fever which can reach 39°C, (102.2 °F)
• A petechial or maculopapular rash usually involving the limbs and trunk
• Arthralgia (bodyache) or arthritis affecting multiple joints which can be debilitating. The joint pains can be severe and even crippling.
There can also be headache, conjunctival infection and slight photophobia. Fever typically lasts for two days and abruptly comes down, however joint pain, intense headache, insomnia and an extreme degree of prostration lasts for a variable period, usually for about 5 to 7 days.
Measles is highly contagious. Infected people are usually contagious from about 4 days before their rash starts to 4 days afterwards. The measles virus resides in the mucus in the nose and throat of infected people. When they sneeze or cough, droplets spray into the air and the droplets remain active and contagious on infected surfaces for up to two hours.
Cause of Measles
Measles is caused by a virus. Symptoms occur generally 8 to 12 days after exposed to the virus. This is called the incubation period. Persons with the measles typically have a fever, cough, redness and irritation of the eyes (conjunctivitis), and a rash that spreads. Those who have had an active measles infection or who have been vaccinated against the measles have immunity to the disease.
Symptoms of Measles
• Sore throat
• Runny nose
•Cough
• Muscle pain
• Fever
• Bloodshot eyes
• Tiny white spots inside the mouth (Koplik’s spots)
• Photophobia (light sensitivity)
• Rash
• Usually appears 3 to 5 days after the first signs of being sick
• May last 4 to 7 days
• Usually starts on the head and spreads to other areas, moving down the body
• Rash may appear as flat, discolored areas (macules) and solid, red, raised areas (papules) that later join together
• Itchy
After successful vaccination campaigns, the WHO in 1980 declared the eradication of smallpox. Because of these efforts, not one documented naturally occurring case of this once high-mortality infection has occurred since October 26, 1977.
Signs and Symptoms of Mumps, Parotitis
Cases of mumps may start with a fever of up to 103 degrees Fahrenheit (39.4 degrees Celsius), as well as a headache and loss of appetite. The well-known hallmark of mumps is swelling and pain in the parotid glands. The glands usually become increasingly swollen and painful over a period of 1 to 3 days. The pain gets worse when the child swallows, talks, chews, or drinks acidic juices (like orange juice).
In rare cases, mumps will attack other groups of salivary glands instead of the parotids. If this happens, swelling may be noticed under the tongue, under the jaw, or all the way down to the front of the chest.
Mumps can lead to inflammation and swelling of the brain and other organs, although this is not common. Encephalitis (inflammation of the brain) and meningitis (inflammation of the lining of the brain and spinal cord) are both rare complications of mumps. Symptoms appear in the first week after the parotid glands begin to swell and may include: high fever, stiff neck, headache, nausea and vomiting, drowsiness, convulsions, and other signs of brain involvement.
Mumps in adolescent and adult males may also result in the development of orchitis, an inflammation of the testicles. Usually one testicle becomes swollen and painful about 7 to 10 days after the parotids swell. This is accompanied by a high fever, shaking chills, headache, nausea, vomiting, and abdominal pain that can sometimes be mistaken for appendicitis if the right testicle is affected. After 3 to 7 days, testicular pain and swelling subside, usually at about the same time that the fever passes. In some cases, both testicles are involved. Even with involvement of both testicles, sterility is only a rare complication of orchitis.
Signs and Symptoms of Typhoid Fever
Persons with typhoid fever usually have a sustained fever as high as 103° to 104° F (39° to 40° C). They may also feel weak, or have stomach pains, headache, or loss of appetite. In some cases, patients have a rash of flat, rose-colored spots. The only way to know for sure if an illness is typhoid fever is to have samples of stool or blood tested for the presence of S. Typhi.
