Fever and its types

              Fever and its types

Fever:An abnormally high body temperature, usually accompanied by shivering, headache, and in severe instances, delirium.

Malaria:
Symptoms of Malaria:

 Malaria is caused by a parasite that is passed from one human to another by the bite of infected Anopheles mosquitoes. After infection, the parasites (called sporozoites) travel through the bloodstream to the liver, where they mature and release another form, the merozoites. The parasites enter the bloodstream and infect red blood cells.
The parasites multiply inside the red blood cells, which then break open within 48 to 72 hours, infecting more red blood cells. The first symptoms usually occur 10 days to 4 weeks after infection, though they can appear as early as 8 days or as long as a year after infection. The symptoms occur in cycles of 48 to 72 hours.
What are the signs and symptoms of malaria?
Symptoms of malaria include fever and flu-like illness, including shaking chills, headache, muscle aches, and tiredness. Nausea, vomiting, and diarrhea may also occur. Malaria may cause anemia and jaundice (yellow coloring of the skin and eyes) because of the loss of red blood cells. Infection with one type of malaria, Plasmodium falciparum, if not promptly treated, may cause kidney failure, seizures, mental confusion, coma, and death.
How soon will a person feel sick after being bitten by an infected mosquito?
For most people, symptoms begin 10 days to 4 weeks after infection, although a person may feel ill as early as 7 days or as late as 1 year later. Two kinds of malaria, P. vivax and P. ovale, can relapse. In P. vivax and P. ovale infections, some parasites can remain dormant in the liver for several months up to about 4 years after a person is bitten by an infected mosquito. When these parasites come out of hibernation and begin invading red blood cells ("relapse"), the person will become sick.


How do I know if I have malaria?
Most people, at the beginning of the disease, have fever, sweats, chills, headaches, malaise, muscles aches, nausea and vomiting. Malaria can very rapidly become a severe and life-threatening disease. The surest way for you and your doctor to know whether you have malaria is to have a diagnostic test where a drop of your blood is examined under the microscope for the presence of malaria parasites.
If you are sick and there is any suspicion of malaria (for example, if you have recently traveled in a malaria-risk area) the test should be performed without delay.

Treatment for Malaria:

Malaria, especially Falciparum malaria, is a medical emergency that requires a hospital stay. Chloroquine is often used as an anti-malarial medication. However, chloroquine-resistant infections are common in some parts of the world.
Possible treatments for chloroquine-resistant infections include:
The combination of quinidine or quinine plus doxycycline, tetracycline, or clindamycin
Atovaquone plus proguanil (Malarone)
Mefloquine or artesunate
The combination of pyrimethamine and sulfadoxine (Fansidar)
The choice of medication depends in part on where you were when you were infected.
Medical care, including fluids through a vein (IV) and other medications and breathing (respiratory) support may be needed.

Symptoms and Treatment of Typhoid:

Typhoid fever is an acute illness associated with fever that is most often caused by the Salmonella typhi bacteria. It can also be caused by Salmonella paratyphi, a related bacterium that usually leads to a less severe illness. The bacteria are deposited in water or food by a human carrier and are then spread to other people in the area. Typhoid fever is rare in industrial countries but continues to be a significant public-health issue in developing countries.
The incidence of typhoid fever in the United States has markedly decreased since the early 1900s. Today, approximately 400 cases are reported annually in the United States, mostly in people who recently have traveled to endemic areas. This is in comparison to the 1920s, when over 35,000 cases were reported in the U.S. This improvement is the result of improved environmental sanitation. Mexico and South America are the most common areas for U.S. citizens to contract typhoid fever. India, Pakistan, and Egypt are also known high-risk areas for developing this disease. Worldwide, typhoid fever affects more than 13 million people annually, with over 500,000 patients dying of the disease.
If traveling to endemic areas, you should consult with your health-care professional and discuss if you should receive vaccination for typhoid fever.
Typhoid fever is contracted by the ingestion of the bacteria in contaminated food or water. Patients with acute illness can contaminate the surrounding water supply through stool, which contains a high concentration of the bacteria. Contamination of the water supply can, in turn, taint the food supply. About 3%-5% of patients become carriers of the bacteria after the acute illness. Some patients suffer a very mild illness that goes unrecognized. These patients can become long-term carriers of the bacteria. The bacteria multiplies in the gallbladder, bile ducts, or liver and passes into the bowel. The bacteria can survive for weeks in water or dried sewage. These chronic carriers may have no symptoms and can be the source of new outbreaks of typhoid fever for many years.

Fluids and electrolytes may be given through a vein (intravenously), or you may be asked to drink uncontaminated water with electrolyte packets.
Appropriate antibiotics are given to kill the bacteria. There are increasing rates of antibiotic resistance throughout the world, so your health care provider will check current recommendations before choosing an antibiotic.

Symptoms &Treatment of Chinkungunya:

Chikungunya fever is a viral disease transmitted to humans by the bite of infected Aedes Aegypti mosquitoes. Chikungunya virus (CHIKV) is a member of the genus Alphavirus, in the family Togaviridae. CHIKV was first isolated from the blood of a febrile patient in Tanzania in 1953, and has since been identified repeatedly in west, central and southern Africa and many areas of Asia, and has been cited as the cause of numerous human epidemics in those areas since that time. The virus circulates throughout much of Africa, with transmission thought to occur mainly between mosquitoes and monkeys.
Symptoms of Chikungunya
Symptoms of Chikungunya includes fever, debilitating arthralgia (joint pain), swelling of joints, stiffness of joints, myalgia (muscular pain), headache, fatigue (weakness), nausea, vomiting and rash.
The incubation period (time from infection to illness) can be 2-12 days, but is usually 3-7 days. "Silent" CHIKV infections (infections without illness) do occur; but how commonly this happens is not yet known.
Acute chikungunya fever typically lasts a few days to a couple of weeks, but some patients have prolonged fatigue lasting several weeks. Additionally, some patients have reported incapacitating joint pain, or arthritis which may last for weeks or months. No deaths, neuro-invasive cases, or hemorrhagic cases related to CHIKV infection have been conclusively documented in the scientific literature.
CHIKV infection (whether clinical or silent) is thought to confer life-long immunity.
Spread of Chikungunya
CHIKV is spread by the bite of an infected mosquito. Mosquitoes become infected when they feed on a person infected with CHIKV. Monkeys, and possibly other wild animals, may also serve as reservoirs of the virus. Infected mosquitoes can then spread the virus to other humans when they bite. Aedes aegypti (the yellow fever mosquito), a household container breeder and aggressive daytime biter which is attracted to humans, is the primary vector of CHIKV to humans. Aedes albopictus (the Asian tiger mosquito) may also play a role in human transmission in Asia, and various forest-dwelling mosquito species in Africa have been found to be infected with the virus.


Treatment of Chikungunya Effective treatment for Chikungunya fever is available in homeopathy.Homeopathy has very effective treatment for Chikungunya. After diagnosis of Chikungunya, homeopathic treatment should be started as early as possible. Homeopathic treatment can also be given along with conventional treatment (allopathy) if desired. Conventional treatment consists of only symptomatic treatment of fever, stiffness, joint pain etc. of this viral illness, whereas homeopathic medicines give better and comparatively long lasting relief from the disease. Rhus Tox, Eupatorium Perf, Bryonia, Arnica are the few homeopathic remedies that help in Chikungunya but more accurate and effective remedy can be chosen by a homeopathic doctor according to clinical picture of that particular case. Homeopathy works effectively in all viral diseases. Homeopathic pills are simply chewed (dissolved) on tongue and are sweet in taste. Homeopathic medicines do not cause gastric irritation, are safe on kidneys and liver even when taken for long duration.

In epidemics, prevention of Chikungunya can be achieved  by administering Homeopathic "Genus Epidemicus". Genus Epidemicus is a homeopathic remedy that is chosen as a preventive remedy for that particular epidemic in that particular locality. Homeopathic medicines are equally effective for post-chikungunya complaints like weakness, stiffness in joints, muscles pain etc. Infected persons should be protected from further mosquito exposure (staying indoors and/or under a mosquito net during the first few days of illness) so that they can't contribute to the transmission cycle.

Prevention of Chikungunya
The best way to avoid CHIKV infection is to prevent mosquito bites. In addition we strongly recommend to have "Homeopathic Genus Epidemicus" for double protection. 
Prevention tips:
• Use mosquito repellent on exposed skin.
• Wear long sleeves shirts and pants.
• Have secure screens on windows and doors to keep mosquitoes out.
• Get rid of mosquito breeding sites by emptying standing water from flower pots, buckets and barrels. Change the water in pet dishes and replace the water in bird baths weekly. Drill holes in tire swings so water drains out.
• Additionally, a person with chikungunya fever should limit their exposure to mosquito bites in order to avoid further spreading the infection. The person should stay indoors or under a mosquito net.

Symptoms of Dengue Fever:

Symptoms, which usually begin four to six days after infection and last for up to 10 days, may include
Sudden, high fever
Severe headaches
Pain behind the eyes
Severe joint and muscle pain
Nausea
Vomiting
Skin rash, which appears three to four days after the onset of fever
Mild bleeding (such a nose bleed, bleeding gums, or easy bruising)
Sometimes symptoms are mild and can be mistaken for those of the flu or another viral infection. Younger children and people who have never had the infection before tend to have milder cases than older children and adults. However, serious problems can develop. These include dengue hemorrhagic fever, a rare complication characterized by high fever, damage to lymph and blood vessels, bleeding from the nose and gums, enlargement of the liver, and failure of the circulatory system. The symptoms may progress to massive bleeding, shock, and death. This is called dengue shock syndrome (DSS).
People with weakened immune systems as well as those with a second or subsequent dengue infection are believed to be at greater risk for developing dengue hemorrhagic fever.

Diagnosing Dengue Fever
Doctors can diagnose dengue infection with a blood test to check for the virus or antibodies to it. If you become sick after traveling to a tropical area, let your doctor know. This will allow your doctor to evaluate the possibility that your symptoms were caused by a dengue infection.

Treatment for Dengue Fever:

There is no specific medicine to treat dengue infection. If you think you may have dengue fever, you should use pain relievers with acetaminophen and avoid medicines with aspirin, which could worsen bleeding. You should also rest, drink plenty of fluids, and see your doctor. If you start to feel worse in the first 24 hours after your fever goes down, you should get to a hospital immediately to be checked for complications.


Symptoms of Swine Flu:

What are the symptoms of swine flu (H1N1)?
Symptoms of swine flu are similar to most influenza infections: fever (100 F or greater), cough, nasal secretions, fatigue, and headache, with fatigue being reported in most infected individuals. Some patients also get nausea, vomiting, and diarrhea. In Mexico, many of the initial patients infected with H1N1 influenza were young adults, which made some investigators speculate that a strong immune response, as seen in young people, may cause some collateral tissue damage.
Some patients develop severe respiratory symptoms and need respiratory support (such as a ventilator to breathe for the patient). Patients can get pneumonia (bacterial secondary infection) if the viral infection persists, and some can develop seizures. Death often occurs from secondary bacterial infection of the lungs; appropriate antibiotics need to be used in these patients. The usual mortality (death) rate for typical influenza A is about 0.1%, while the 1918 "Spanish flu" epidemic had an estimated mortality rate ranging from 2%-20%. Swine (H1N1) flu in Mexico had about 160 deaths and about 2,500 confirmed cases, which would correspond to a mortality rate of about 6%, but these initial data have been revised and the mortality rate currently worldwide is estimated to be much lower. By June 2009, the virus had reached 74 different countries on every continent except Antarctica, and by September 2009, the virus had been reported in most countries (over 200) in the world. Fortunately, the mortality rate as of H1N1 has remained low and similar to that of the conventional flu (average conventional flu mortality rate is about 36,000 per year; projected H1N1 flu mortality rate was 90,000 per year in the U.S. as determined by the president's advisory committee, but it never approached that high number).
Fortunately, although H1N1 developed into a pandemic (worldwide) flu strain, the mortality rate in the U.S. and many other countries only approximated the usual numbers of flu deaths worldwide. Speculation about why the mortality rate remained much lower than predicted includes increased public awareness and action that produced an increase in hygiene (especially hand washing), a fairly rapid development of a new vaccine, and patient self-isolation if symptoms developed

Treatment of Swine Flu:

The best treatment for influenza infections in humans is prevention by vaccination. Work by several laboratories has recently produced vaccines. The first vaccine released in early October 2009 was a nasal spray vaccine that was approved for use in healthy individuals ages 2 through 49. The injectable vaccine, made from killed H1N1, became available in the second week of October 2009. This vaccine was approved for use in ages 6 months to the elderly, including pregnant females. Both of these vaccines were approved by the CDC only after they had conducted clinical trials to prove that the vaccines were safe and effective. However, caregivers should be aware of the vaccine guidelines that come with the vaccines, as occasionally, the guidelines change. Please see the section below titled "Can novel H1N1 swine flu be prevented with a vaccine?"
Almost all vaccines have some side effects. Common side effects of H1N1 vaccines are typical of flu vaccines and are as follows:
Flu shot: Soreness, redness, minor swelling at the shot site, muscle aches, low grade fever, and nausea do not usually last more than about 24 hours.
Nasal spray: runny nose, low-grade fever, vomiting, headache, wheezing, cough, and sore throat
The flu shot is made from killed virus particles so a person cannot get the flu from a flu shot. However, the nasal spray vaccine contains live virus that have been altered to hinder its ability to replicate in human tissue. People with a suppressed immune system should not get vaccinated with the nasal spray. Also, most vaccines that contain flu viral particles are cultivated in eggs, so individuals with an allergy to eggs should not get the vaccine unless tested and advised by their doctor that they are cleared to obtain it. Like all vaccines, rare events may occur in some rare cases (for example, swelling, weakness, or shortness of breath). If any symptoms like these develop, the person should see a physician immediately.


Two antiviral agents have been reported to help prevent or reduce the effects of swine flu. They are zanamivir (Relenza) and oseltamivir (Tamiflu), both of which are also used to prevent or reduce influenza A and B symptoms. These drugs should not be used indiscriminately, because viral resistance to them can and has occurred. Also, they are not recommended if the flu symptoms already have been present for 48 hours or more, although hospitalized patients may still be treated past the 48-hour guideline. Severe infections in some patients may require additional supportive measures such as ventilation support and treatment of other infections like pneumonia that can occur in patients with a severe flu infection. The CDC has suggested in their interim guidelines that pregnant females can be treated with the two antiviral agents.

Symptoms &Treatment of Cholera:

The symptoms and signs of cholera are a watery diarrhea that often contains flecks of whitish material (mucus and some epithelial cells) that are about the size of pieces of rice. The diarrhea is termed "rice-water stool" (See figure 1) and smells "fishy." The volume of diarrhea can be enormous; high levels of diarrheal fluid such as 250 cc per kg or about 10 to 18 liters over 24 hours for a 70 kg adult can occur. People may go on to develop one or more of the following symptoms and signs:

Vomiting
Rapid heart rate
Loss of skin elasticity (washer woman hands sign; see figure 2)
Dry mucous membranes
Low blood pressure
Thirst
Muscle cramps
Restlessness or irritability (especially in children)
Those infected require immediate hydration to prevent these symptoms from continuing because these signs and symptoms indicate that the person is becoming or is dehydrated and may go on to develop severe cholera. People with severe cholera (about 5%-10% of previously healthy people; higher if a population is compromised by poor nutrition or has a high percentage of very young or elderly people) can develop severe dehydration, leading to acute renal failure, severe electrolyte imbalances (especially potassium and sodium), and coma. If untreated, this severe dehydration can rapidly lead to shock and death. Severe dehydration can often occur four to eight hours after the first liquid stool, ending with death in about 18 hours to a few days in undertreated or untreated people. In epidemic outbreaks in underdeveloped countries where little or no treatment is available, the mortality (death) rate can be as high as 50%-60%.

Although there is a vaccine against cholera, the CDC and World Health Organization don't normally recommend it because it may not protect up to half of the people who receive it and it lasts only a few months. However, you can protect yourself and your family by using only water that has been boiled, water that has been chemically disinfected, or bottled water. Be sure to use the bottled, boiled, or chemically disinfected water for the following purposes:

Drinking
Preparing food or drinks
Making ice
Brushing your teeth
Washing your face and hands
Washing dishes and utensils that you use to eat or prepare food
Washing fruits and vegetables.
