how is hps diagnosed and treated for Hantavirus ? 

Diagnosing HPS
  
Diagnosing HPS in an individual who has only been infected a few days is difficult, because early symptoms such as fever, muscle aches, and fatigue are easily confused with influenza. However, if the individual is experiencing fever and fatigue and has a history of potential rural rodent exposure, together with shortness of breath, would be strongly suggestive of HPS. If the individual is experiencing these symptoms they should see their physician immediately and mention their potential rodent exposure.
  Treating HPS
  
    
      
     
   
  
  
There is no specific treatment, cure, or vaccine for hantavirus infection. However, we do know that if infected individuals are recognized early and receive medical care in an intensive care unit, they may do better. In intensive care, patients are intubated and given oxygen therapy to help them through the period of severe respiratory distress.
  
The earlier the patient is brought in to intensive care, the better. If a patient is experiencing full distress, it is less likely the treatment will be effective.
  
Therefore, if you have been around rodents and have symptoms of fever, deep muscle aches, and severe shortness of breath, see your doctor immediately. Be sure to tell your doctor that you have been around rodents—this will alert your physician to look closely for any rodent-carried disease, such as HPS.
what are the symptoms for Hantavirus ? 

Due to the small number of HPS cases, the "incubation time" is not positively known. However, on the basis of limited information, it appears that symptoms may develop between 1 and 5 weeks after exposure to fresh urine, droppings, or saliva of infected rodents.
  Early Symptoms
  
    
   
Early symptoms include fatigue, fever and muscle aches, especially in the large muscle groups—thighs, hips, back, and sometimes shoulders. These symptoms are universal.
   
There may also be headaches, dizziness, chills, and abdominal problems, such as nausea, vomiting, diarrhea, and abdominal pain. About half of all HPS patients experience these symptoms.
  
  Late Symptoms
  
    
   
Four to 10 days after the initial phase of illness, the late symptoms of HPS appear. These include coughing and shortness of breath, with the sensation of, as one survivor put it, a "...tight band around my chest and a pillow over my face" as the lungs fill with fluid.
  
  Is the Disease Fatal?
  
Yes. HPS can be fatal. It has a mortality rate of 38%.
how can hps be prevented for Hantavirus ? 

Eliminate or minimize contact with rodents in your home, workplace, or campsite. If rodents don't find that where you are is a good place for them to be, then you're less likely to come into contact with them. Seal up holes and gaps in your home or garage. Place traps in and around your home to decrease rodent infestation. Clean up any easy-to-get food.
  
Recent research results show that many people who became ill with HPS developed the disease after having been in frequent contact with rodents and/or their droppings around a home or a workplace. On the other hand, many people who became ill reported that they had not seen rodents or rodent droppings at all. Therefore, if you live in an area where the carrier rodents are known to live, try to keep your home, vacation place, workplace, or campsite clean.
  
For more information on how you can prevent rodent infestations, the following information is available on the CDC Rodents site:

How to prevent Q Fever ? 

In the United States, Q fever outbreaks have resulted mainly from occupational exposure involving veterinarians, meat processing plant workers, sheep and dairy workers, livestock farmers, and researchers at facilities housing sheep. Prevention and control efforts should be directed primarily toward these groups and environments. 
 
The following measures should be used in the prevention and control of Q fever: 
  
  - Educate the public on sources of infection.  
  - Appropriately dispose of placenta, birth products, fetal membranes, and aborted fetuses at facilities housing sheep and goats.  
  - Restrict access to barns and laboratories used in housing potentially infected animals.   
  - Use appropriate procedures for bagging, autoclaving, and washing of laboratory clothing.  
  - Vaccinate (where possible) individuals engaged in research with pregnant sheep or live C. burnetii.  
  - Quarantine imported animals.  
  - Ensure that holding facilities for sheep should be located away from populated areas. Animals should be routinely tested for antibodies to C. burnetii, and measures should be implemented to prevent airflow to other occupied areas.  
  - Counsel persons at highest risk for developing chronic Q fever, especially persons with pre-existing cardiac valvular disease or individuals with vascular grafts.  
  
 
A vaccine for Q fever has been developed and has successfully protected humans in occupational settings in Australia. However, this vaccine is not commercially available in the United States. Persons wishing to be vaccinated should first have a skin test to determine a history of previous exposure. Individuals who have previously been exposed to C. burnetii should not receive the vaccine because severe reactions, localized to the area of the injected vaccine, may occur. A vaccine for use in animals has also been developed, but it is not available in the United States. 
 Significance for Bioterrorism 
 
Coxiella burnetii is a highly infectious agent that is rather resistant to heat and drying. It can become airborne and inhaled by humans. A single C. burnetii organism may cause disease in a susceptible person. This agent has a past history of being developed for use in biological warfare and is considered a potential terrorist threat.
Who is at risk for Hendra Virus Disease (HeV)? ? 

Transmission of Hendra virus to humans can occur after exposure to body fluids and tissues or excretions of horses infected with Hendra virus. 
 
Horses may be infected after exposure to virus in the urine of infected flying foxes. 
 
To date, no human-to-human transmission has been documented.
What are the symptoms of Hendra Virus Disease (HeV) ? 

After an incubation of 9-16 days, infection with Hendra virus can lead to respiratory illness with severe flu-like signs and symptoms. In some cases, illness may progress to encephalitis. 
                
Although infection with Hendra virus is rare, the case fatality is high: 4/7 (57%).
Who is at risk for Hendra Virus Disease (HeV)? ? 

Australia’s “Flying fox” bats (genus Pteropus) are the natural reservoir of Hendra virus. Serologic evidence for HeV infection have been found in all fours species of Australian flying foxes, but spillover of the virus in horses is limited to coastal and forested regions in Australia (Queensland and New South Wales states)  (see Henipavirus Distribution Map). 
                
People at highest risk are those living within the distribution of the flying foxes and with occupational or recreational exposure to horses that have had potential contact with flying foxes in Australia.
How to diagnose Hendra Virus Disease (HeV) ? 

Laboratory tests that are used to diagnose Hendra virus (HV) and Nipah virus (NV) include detection of antibody by ELISA (IgG and IgM), real time polymerase chain reaction (RT-PCR), and virus isolation attempts.  In most countries, handling Hendra virus needs to be done in high containment laboratories. Laboratory diagnosis of a patient with a clinical history of HV or NV can be made during the acute and convalescent phase of the disease by using a combination of tests including detection of antibody in the serum or the cerebrospinal fluid (CSF), viral RNA detection (RT-PCR) in the serum, CSF, or throat swabs, and virus isolation from the CSF or throat swabs.
What are the treatments for Hendra Virus Disease (HeV) ? 

The drug ribavirin has been shown to be effective against the viruses in vitro, but the clinical usefulness of this drug is uncertain. 
                
A post-exposure therapy with a Nipah/Hendra neutralizing antibody, efficacious in animal models is in human preclinical development stages in Australia.
How to prevent Hendra Virus Disease (HeV) ? 

The occurrence of the disease in humans has been associated only with infection of an intermediate species such as horses.  Early recognition of the disease in the intermediate animal host is probably the most crucial means of limiting future human cases.  
                
Hendra virus infection can be prevented by avoiding horses that are ill or may be infected with HeV and using appropriate personal protective equipment when contact is necessary, as in veterinary procedures. 
                
A commercial vaccine has been recently licensed in Australia for horses and could be beneficial for other animal species and eventually humans.
What is (are) Parasites - Zoonotic Hookworm ? 

There are many different species of hookworms, some are human parasites and some are animal parasites. People can be infected by larvae of animal hookworms, usually dog and cat hookworms. The most common result of animal hookworm infection is a skin condition called cutaneous larva migrans.
Who is at risk for Parasites - Zoonotic Hookworm? ? 

Dog and cat hookworms are found throughout the world, especially in warmer climates. In the United States, zoonotic hookworms are found everywhere but more commonly along the East Coast than the West Coast. Worldwide, zoonotic hookworms are found in tropical and subtropical regions where the parasite is better able to survive because of environmental conditions. However, there is one type of dog and cat hookworm that is more commonly found in cooler climates.
    
The global burden of zoonotic hookworm in dogs and cats is not known; also, the amount of disease in people caused by these parasites is also unknown. Cutaneous larva migrans (CLM) is most often reported by returning travelers to tropical regions who have had soil and/or sand exposures in places where dogs and cats are likely to have hookworms. However, CLM is likely causing significant problems for the people who live in less developed parts of the world, even though the disease is not reported regularly. In less developed areas of the world, dogs and cats are often free-ranging and have high rates of infection with hookworm which leads to widespread contamination of sand and soil. In a survey of a rural population in Brazil, the prevalence of CLM during the rainy season was 14.9% among children less than 5 years old and 0.7% among adults aged 20 years and older.
How to diagnose Parasites - Zoonotic Hookworm ? 

Cutaneous larva migrans (CLM) is a clinical diagnosis based on the presence of the characteristic signs and symptoms, and exposure history to zoonotic hookworm. For example, the diagnosis can be made based on finding red, raised tracks in the skin that are very itchy. This is usually found on the feet or lower part of the legs on persons who have recently traveled to tropical areas and spent time at the beach. There is no blood test for zoonotic hookworm infection. Persons who think they have CLM should consult their health care provider for accurate diagnosis.
What are the treatments for Parasites - Zoonotic Hookworm ? 

The zoonotic hookworm larvae that cause cutaneous larva migrans (CLM) usually do not survive more than 5 – 6 weeks in the human host. In most patients with CLM, the signs and symptoms resolve without medical treatment. However, treatment may help control symptoms and help prevent secondary bacterial infections. Antiparasitic treatments may be prescribed by your health care provider.

How to prevent Parasites - Zoonotic Hookworm ? 

Wearing shoes and taking other protective measures to avoid skin contact with sand or soil will prevent infection with zoonotic hookworms. Travelers to tropical and subtropical climates, especially where beach exposures are likely, should be advised to wear shoes and use protective mats or other coverings to prevent direct skin contact with sand or soil. Routine veterinary care of dogs and cats, including regular deworming, will reduce environmental contamination with zoonotic hookworm eggs and larvae. Prompt disposal of animal feces prevents eggs from hatching and contaminating soil -- which makes it important for control of this parasitic infection.
What is (are) Chronic Fatigue Syndrome (CFS) ? 

Chronic fatigue syndrome, or CFS, is a devastating and complex disorder. People with CFS have overwhelming fatigue and a host of other symptoms that are not improved by bed rest and that can get worse after physical activity or mental exertion. They often function at a substantially lower level of activity than they were capable of before they became ill.
  
Besides severe fatigue, other symptoms include muscle pain, impaired memory or mental concentration, insomnia, and post-exertion malaise lasting more than 24 hours. In some cases, CFS can persist for years.
  
Researchers have not yet identified what causes CFS, and there are no tests to diagnose CFS. Moreover, because many illnesses have fatigue as a symptom, doctors need to take care to rule out other conditions, which may be treatable.
How to diagnose Chronic Fatigue Syndrome (CFS) ? 

Diagnostic Challenges
  
For doctors, diagnosing chronic fatigue syndrome (CFS) can be complicated by a number of factors:
  
   - There's no lab test or biomarker for CFS.
   - Fatigue and other symptoms of CFS are common to many illnesses.
   - For some CFS patients, it may not be obvious to doctors that they are ill.
   - The illness has a pattern of remission and relapse.
   - Symptoms vary from person to person in type, number, and severity.
  
  
These factors have contributed to a low diagnosis rate. Of the one to four million Americans who have CFS, less than 20% have been diagnosed.
  Exams and Screening Tests for CFS
  
Because there is no blood test, brain scan, or other lab test to diagnose CFS, the doctor should first rule out other possible causes.
  
If a patient has had 6 or more consecutive months of severe fatigue that is reported to be unrelieved by sufficient bed rest and that is accompanied by nonspecific symptoms, including flu-like symptoms, generalized pain, and memory problems, the doctor should consider the possibility that the patient may have CFS. Further exams and tests are needed before a diagnosis can be made:
  
   - A detailed medical history will be needed and should include a review of medications that could be causing the fatigue and symptoms
   - A thorough physical and mental status examination will also be needed
   - A battery of laboratory screening tests will be needed to help identify or rule out other possible causes of the symptoms that could be treated
   - The doctor may also order additional tests to follow up on results of the initial screening tests
  
  
A CFS diagnosis requires that the patient has been fatigued for 6 months or more and has 4 of the 8 symptoms for CFS for 6 months or more. If, however, the patient has been fatigued for 6 months or more but does not have four of the eight symptoms, the diagnosis may be idiopathic fatigue.
  
The complete process for diagnosing CFS can be found here.

What are the treatments for Chronic Fatigue Syndrome (CFS) ? 

Introduction
  
Managing chronic fatigue syndrome can be as complex as the illness itself. There is no cure, no prescription drugs have been developed specifically for CFS, and symptoms can vary a lot over time. Thus, people with CFS should closely monitor their health and let their doctor know of any changes; and doctors should regularly monitor their patients' conditions and change treatment strategies as needed.
  
A team approach that involves doctors and patients is one key to successfully managing CFS. Patients and their doctors can work together to create an individualized treatment program that best meets the needs of the patient with CFS. This program should be based on a combination of therapies that address symptoms, coping techniques, and managing normal daily activities.
  
CFS affects patients in different ways, and the treatment plan should be tailored to address symptoms that are most disruptive or disabling for each patient. Helping the patient get relief from symptoms is the main goal of treatment. However, expecting a patient to return to usual activities should not be the immediate goal because the physical and mental exertion needed to try to reach that goal may aggravate the illness.
  
Because CFS is a complicated illness, its management may require input from a variety of medical professionals. Primary care providers can develop effective treatment plans based on their experience in treating other illnesses. Patients benefit when they can work in collaboration with a team of doctors and other health care professionals, who might also include rehabilitation specialists, mental health professionals, and physical or exercise therapists.
  Difficulties of Living with CFS
  
Living with chronic fatigue syndrome can be difficult. Like other debilitating chronic illnesses, CFS can have a devastating impact on patients' daily lives and require them to make major lifestyle changes to adapt to many new limitations.
  
Common difficulties for CFS patients include problems coping with:
  
   - the changing and unpredictable symptoms
   - a decrease in stamina that interferes with activities of daily life
   - memory and concentration problems that seriously hurt work or school performance
   - loss of independence, livelihood, and economic security
   - alterations in relationships with partners, family members, and friends
   - worries about raising children
  
  
Feelings of anger, guilt, anxiety, isolation and abandonment are common in CFS patients. While it's OK to have such feelings, unresolved emotions and stress can make symptoms worse, interfere with prescription drug therapies, and make recovery harder.
