Question:  What is (are) Parasites - Scabies ?
Answer: Scabies is an infestation of the skin by the human itch mite (Sarcoptes scabiei var. hominis). The microscopic scabies mite burrows into the upper layer of the skin where it lives and lays its eggs. The most common symptoms of scabies are intense itching and a pimple-like skin rash. The scabies mite usually is spread by direct, prolonged, skin-to-skin contact with a person who has scabies.
Scabies is found worldwide and affects people of all races and social classes. Scabies can spread rapidly under crowded conditions where close body and skin contact is frequent. Institutions such as nursing homes, extended-care facilities, and prisons are often sites of scabies outbreaks. Child care facilities also are a common site of scabies infestations.
Question:  Who is at risk for Parasites - Scabies? ?
Answer: Transmission
    
Human scabies is caused by an infestation of the skin by the human itch mite (Sarcoptes scabiei var. hominis). The adult female scabies mites burrow into the upper layer of the skin (epidermis) where they live and deposit their eggs. The microscopic scabies mite almost always is passed by direct, prolonged, skin-to-skin contact with a person who already is infested. An infested person can spread scabies even if he or she has no symptoms. Humans are the source of infestation; animals do not spread human scabies.
    Persons At Risk
    
Scabies can be passed easily by an infested person to his or her household members and sexual partners. Scabies in adults frequently is sexually acquired.
    
Scabies is a common condition found worldwide; it affects people of all races and social classes. Scabies can spread easily under crowded conditions where close body and skin contact is common. Institutions such as nursing homes, extended-care facilities, and prisons are often sites of scabies outbreaks. Child care facilities also are a common site of scabies infestations.
    Crusted (Norwegian) Scabies
    
Some immunocompromised, elderly, disabled, or debilitated persons are at risk for a severe form of scabies called crusted, or Norwegian, scabies. Persons with crusted scabies have thick crusts of skin that contain large numbers of scabies mites and eggs. The mites in crusted scabies are not more virulent than in non-crusted scabies; however, they are much more numerous (up to 2 million per patient). Because they are infested with such large numbers of mites, persons with crusted scabies are very contagious to other persons. In addition to spreading scabies through brief direct skin-to-skin contact, persons with crusted scabies can transmit scabies indirectly by shedding mites that contaminate items such as their clothing, bedding, and furniture. Persons with crusted scabies should receive quick and aggressive medical treatment for their infestation to prevent outbreaks of scabies.
Question:  How to diagnose Parasites - Scabies ?
Answer: Diagnosis of a scabies infestation usually is made based upon the customary appearance and distribution of the the rash and the presence of burrows.
    
Whenever possible, the diagnosis of scabies should be confirmed by identifying the mite or mite eggs or fecal matter (scybala). This can be done by carefully removing the mite from the end of its burrow using the tip of a needle or by obtaining a skin scraping to examine under a microscope for mites, eggs, or mite fecal matter (scybala). However, a person can still be infested even if mites, eggs, or fecal matter cannot be found; fewer then 10-15 mites may be present on an infested person who is otherwise healthy.
Question:  What are the treatments for Parasites - Scabies ?
Answer: Suggested General Guidelines 
  
    
   
  
It is important to remember that the first time a person gets scabies they usually have no symptoms during the first 2 to 6 weeks they are infested; however they can still spread scabies during this time. 
  
Treatment should be given to both the infested person and to household members and sexual contacts, particularly those who have had prolonged direct skin-to-skin contact with the infested person. Both sexual and close personal contacts who have had direct prolonged skin-to-skin contact with an infested person within the preceding month should be examined and treated. All persons should be treated at the same time to prevent reinfestation. Scabies may sometimes be sexually-acquired in adults, but is rarely sexually-acquired in children. 
  
Bedding, clothing, and towels used by infested persons or their household, sexual, and close contacts (as defined above) anytime during the three days before treatment should be decontaminated by washing in hot water and drying in a hot dryer, by dry-cleaning, or by sealing in a plastic bag for at least 72 hours. Scabies mites generally do not survive more than 2 to 3 days away from human skin. 
  
Use of insecticide sprays and fumigants is not recommended. 
    
  Medications Used to Treat Scabies 
  
    
   
  
Products used to treat scabies are called scabicides because they kill scabies mites; some also kill mite eggs. Scabicides used to treat human scabies are available only with a doctor’s prescription. No “over-the-counter” (non-prescription) products have been tested and approved to treat scabies. 
  
Scabicide should be applied to all areas of the body from the neck down to the feet and toes. In addition, when treating infants and young children, scabicide also should be applied to their entire head and neck because scabies can affect their face, scalp, and neck, as well as the rest of their body. The scabicide should be applied to a clean body and left on for the recommended time before washing it off. Clean clothing should be worn after treatment. 
  
The instructions contained in the box or printed on the label always should be followed carefully. Always contact a doctor or pharmacist if unsure how to use a particular medicine. 
  
Because the symptoms of scabies are due to a hypersensitivity reaction (allergy) to mites and their feces (scybala), itching still may continue for several weeks after treatment even if all the mites and eggs are killed. If itching still is present more than 2 to 4 weeks after treatment or if new burrows or pimple-like rash lesions continue to appear, retreatment may be necessary. 
  
Skin sores that become infected should be treated with an appropriate antibiotic prescribed by a doctor.
Question:  How to prevent Parasites - Scabies ?
Answer: When a person is infested with scabies mites the first time, symptoms may not appear for up to two months after being infested. However, an infested person can transmit scabies, even if they do not have symptoms. Scabies usually is passed by direct, prolonged skin-to-skin contact with an infested person. However, a person with crusted (Norwegian) scabies can spread the infestation by brief skin-to-skin contact or by exposure to bedding, clothing, or even furniture that he/she has used.
    
Scabies is prevented by avoiding direct skin-to-skin contact with an infested person or with items such as clothing or bedding used by an infested person. Scabies treatment usually is recommended for members of the same household, particularly for those who have had prolonged skin-to-skin contact. All household members and other potentially exposed persons should be treated at the same time as the infested person to prevent possible reexposure and reinfestation. Bedding and clothing worn or used next to the skin anytime during the 3 days before treatment should be machine washed and dried using the hot water and hot dryer cycles or be dry-cleaned. Items that cannot be dry-cleaned or laundered can be disinfested by storing in a closed plastic bag for several days to a week. Scabies mites generally do not survive more than 2 to 3 days away from human skin. Children and adults usually can return to child care, school, or work the day after treatment.
    
Persons with crusted scabies and their close contacts, including household members, should be treated rapidly and aggressively to avoid outbreaks. Institutional outbreaks can be difficult to control and require a rapid, aggressive, and sustained response.
    
Rooms used by a patient with crusted scabies should be thoroughly cleaned and vacuumed after use. Environmental disinfestation using pesticide sprays or fogs generally is unnecessary and is discouraged.
Question:  Who is at risk for Alkhurma Hemorrhagic Fever (AHF)? ?
Answer: Transmission of AHFV is not well understood. AHFV is a zoonotic virus, and its described tick hosts (the soft tick Ornithodoros savignyi and the hard tick Hyalomma dromedari) are widely distributed. People can become infected through a tick bite or when crushing infected ticks. Epidemiologic studies indicate that contact with domestic animals or livestock may increase the risk of human infection. No human-to-human transmission of AHF has been documented. 
 
Although livestock animals may provide blood meals for ticks, it is thought that they play a minor role in transmitting AHFV to humans. No transmission through non-pasteurized milk has been described, although other tick-borne flaviviruses have been transmitted to humans through this route.
Question:  What are the symptoms of Alkhurma Hemorrhagic Fever (AHF) ?
Answer: Based on limited information, after an incubation period that could be as short as 2-4 days, the disease presents initially with non-specific flu-like symptoms, including fever, anorexia (loss of appetite), general malaise, diarrhea, and vomiting; a second phase has appeared in some patients, and includes neurologic and hemorrhagic symptoms in severe form. Multi-organ failure precedes fatal outcomes. No repeated or chronic symptoms have been reported following recovery. Evidence suggests that a milder form may exist, where hospitalization is not required. 
                
Thrombocytopenia, leukopenia, and elevated liver enzymes are nearly always observed in patients who have been hospitalized.
Question:  Who is at risk for Alkhurma Hemorrhagic Fever (AHF)? ?
Answer: Contact with  livestock with tick exposure are risk factors for humans, as is contact with infected ticks, whether through crushing the infected tick with unprotected fingers or by a bite from an infected tick. Slaughtering of animals which may acutely but asymptomatically infected may also be a risk factor, as it is possible that infected animals develop a viremia without obvious clinical signs.
Question:  How to diagnose Alkhurma Hemorrhagic Fever (AHF) ?
Answer: Clinical diagnosis could be difficult due to similarities between AVHF, Crimean-Congo Hemorrhagic fever (CCHF), and Rift Valley fever (RVF), which occur in similar geographic areas. Laboratory diagnosis of AHF can be made in the early stage of the illness by molecular detection by PCR or virus isolation from blood. Later, serologic testing using enzyme-linked immunosorbent serologic assay (ELISA) can be performed.
Question:  What are the treatments for Alkhurma Hemorrhagic Fever (AHF) ?
Answer: There is no standard specific treatment for the disease. Patients receive supportive therapy, which consists of balancing the patient’s fluid and electrolytes, maintaining oxygen status and blood pressure, and treatment for any complications. Mortality in hospitalized patients ranges from 1-20%.
Question:  How to prevent Alkhurma Hemorrhagic Fever (AHF) ?
Answer: Given that no treatment or specific prophylaxis is presently available, prevention and increased awareness of AHFV are the only recommended measures. Complete control of ticks and interruption of the virus life cycle is impractical; in endemic regions, it is important to avoid tick-infested areas and to limit contact with livestock and domestic animals.  
                
Individuals should use tick repellants on skin and clothes and check skin for attached ticks, removing them as soon as possible. Tick collars are available for domestic animals, and dipping in acaricides is effective in killing ticks on livestock. People working with animals or animal products in farms or slaughterhouses should avoid unprotected contact with the blood, fluids, or tissues of any potentially infected or viremic animals.
Question:  What is (are) Parasites - Taeniasis ?
Answer: Taeniasis in humans is a parasitic infection caused by the tapeworm species Taenia saginata (beef tapeworm), Taenia solium (pork tapeworm), and Taenia asiatica (Asian tapeworm). Humans can become infected with these tapeworms by eating raw or undercooked beef (T. saginata) or pork (T. solium and T. asiatica). People with taeniasis may not know they have a tapeworm infection because symptoms are usually mild or nonexistent.

T. solium tapeworm infections can lead to cysticercosis, which is a disease that can cause seizures, so it is important seek treatment.
Question:  Who is at risk for Parasites - Taeniasis? ?
Answer: The tapeworms that cause taeniasis (Taenia saginata, T. solium, and T. asiatica) are found worldwide. Eating raw or undercooked beef or pork is the primary risk factor for acquiring taeniasis. Persons who don't eat raw or undercooked beef or pork are not likely to get taeniasis.
    
Infections with T. saginata occur wherever contaminated raw beef is eaten, particularly in Eastern Europe, Russia, eastern Africa and Latin America. Taeniasis due to T. saginata is rare in the United States, except in places where cattle and people are concentrated and sanitation is poor, such as around feed lots when cattle can be exposed to human feces. Tapeworm infections due to T. solium are more prevalent in under-developed communities with poor sanitation and where people eat raw or undercooked pork. Higher rates of illness have been seen in people in Latin America, Eastern Europe, sub-Saharan Africa, India, and Asia. Taenia solium taeniasis is seen in the United States, typically among Latin American immigrants. Taenia asiatica is limited to Asia and is seen mostly in the Republic of Korea, China, Taiwan, Indonesia, and Thailand.
    
A disease called cysticercosis can occur when T. solium tapeworm eggs are ingested. For example, people with poor hygiene who have taeniasis -- with or without symptoms -- will shed tapeworm eggs in their feces and might accidentally contaminate their environment. This can lead to transmission of cysticercosis to themselves or others.

Question:  How to diagnose Parasites - Taeniasis ?
Answer: Diagnosis of Taenia tapeworm infections is made by examination of stool samples; individuals should also be asked if they have passed tapeworm segments. Stool specimens should be collected on three different days and examined in the lab for Taenia eggs using a microscope. Tapeworm eggs can be detected in the stool 2 to 3 months after the tapeworm infection is established.
    
Tapeworm eggs of T. solium can also infect humans, causing cysticercosis. It is important to diagnose and treat all tapeworm infections.

Question:  What are the treatments for Parasites - Taeniasis ?
Answer: Treatment is available after accurate diagnosis. Your doctor will provide prescription medication, either praziquantel or niclosamide, which is taken by mouth. The medication is also available in a children’s dosage. Work with your health care provider for proper treatment options for you and your family.

Question:  How to prevent Parasites - Taeniasis ?
Answer: One way to prevent taeniasis is to cook meat to safe temperatures. A food thermometer should be used to measure the internal temperature of cooked meat. Do not sample meat until it is cooked. USDA recommends the following for meat preparation.
   
    - For Whole Cuts of Meat (excluding poultry) 
     
      - Cook to at least 145° F (63° C) as measured with a food thermometer placed in the thickest part of the meat, then allow the meat to rest* for three minutes before carving or consuming.
     
    - For Ground Meat (excluding poultry) 
     
      - Cook to at least 160° F (71° C); ground meats do not require a rest* time.
     
   
   
*According to USDA, "A 'rest time' is the amount of time the product remains at the final temperature, after it has been removed from a grill, oven, or other heat source. During the three minutes after meat is removed from the heat source, its temperature remains constant or continues to rise, which destroys pathogens."

Question:  What is (are) Parasites - Baylisascaris infection ?
Answer: Baylisascaris worms are intestinal parasites found in a wide variety of animals. Different species of Baylisascaris are associated with different animal hosts. For example, Baylisascaris procyonis is found in raccoons and Baylisascaris columnaris is an intestinal parasite found in skunks. Cases of Baylisascaris infection in people are not frequently reported, but can be severe. Baylisascaris procyonis is thought to pose the greatest risk to humans because of the often close association of raccoons to human dwellings.
Question:  Who is at risk for Parasites - Baylisascaris infection? ?
Answer: Raccoons are the primary, or definitive, host of Baylisascaris procyonis, a roundworm. Raccoons become infected with Baylisascaris in one of two ways:
    
     - Young raccoons become infected by eating eggs during foraging, feeding, and grooming.
     - Adult raccoons acquire the infection by eating rodents, rabbits, and birds infected with the larvae of Baylisascaris.
    
    
Infected raccoons have been found throughout the United States, mainly in the Midwest, Northeast, Middle Atlantic, and West Coast.
    
Raccoons are peridomestic animals, which means they live in or around areas where people live. Roundworm eggs are passed in the feces of infected raccoons. Raccoons defecate in communal sites, called latrines. Raccoon latrines are often found at bases of trees, unsealed attics, or on flat surfaces such as logs, tree stumps, rocks, decks, and rooftops. As more raccoons move into populated areas, the number and density of their latrines will increase.
    
While raccoons are the roundworm's primary host, other types of animals can become infected. Birds and small mammals, such as rodents and rabbits, are susceptible to the parasite. Unlike raccoons, these animals sometimes show signs of infection, such as muscle spasms, tremors, and progressive weakness; infection can lead to death. Predator animals, including dogs, may become infected by eating an animal that has been infected with Baylisascaris. In some dogs, Baylisascaris may develop to adult worms and pass eggs in the dogs' feces.
    
The worms develop to maturity in the raccoon intestine, where they produce millions of eggs that are passed in the feces. Eggs that are excreted by raccoons are not immediately infectious. These eggs must develop in the environment for 2 to 4 weeks, after which the eggs are able to cause infection. The eggs are resistant to most environmental conditions and with adequate moisture, can survive for years.
    
     
    
    
Humans become infected by ingesting embryonated (fertile) eggs. Anyone who is exposed to environments where raccoons frequent is potentially at risk. Young children or developmentally disabled persons are at highest risk for infection as they may be more likely to put contaminated fingers, soil, or objects into their mouths.
    
Hunters, trappers, taxidermists, and wildlife handlers may also be at increased risk if they have contact with raccoons or raccoon habitats.
    
Fewer than 25 cases of Baylisascaris disease have been documented in the United States. However, it is possible that some cases are incorrectly diagnosed as other infections or go undiagnosed. Cases that are diagnosed tend to be severe.
    
Cases have been reported in California, Illinois, Louisiana, Massachusetts, Michigan, Minnesota, Missouri, New York, Oregon, and Pennsylvania. As of 2012, there were 16 published human neurological cases in the US; six of the infected persons died.
Question:  How to diagnose Parasites - Baylisascaris infection ?
Answer: If you suspect you have been infected, consult your health care provider immediately. Be sure to tell your health care provider if you have recently been exposed to raccoons or their feces.
    
Diagnosis is difficult because symptoms depend on the number of infecting larvae and location in the body. Ocular larva migrans, when the larvae migrate to the eye, can cause sensitivity to light, inflammation of the eye, and blindness. Symptoms of visceral larva migrans, when the larvae travel to organs, depend on which organs are affected. For example, an invasion of the liver may cause hepatomegaly (inflammation and enlargement of the liver), while an invasion of the lung may cause pulmonary symptoms such as cough or chest pain. Larvae rarely end up in the nervous system but the most severe cases are neural larva migrans, when the larvae migrate into the brain and cause it to swell (encephalitis). There is no commercially available test for Baylisascaris infection. A health care provider may test blood, cerebrospinal fluid (CSF), and tissue to determine if an individual is infected. Eye examinations may reveal a migrating larva or lesions and are often the most significant clue to infection with Baylisascaris.
    
Diagnosis often is made by ruling out other infections that cause similar symptoms. Information on diagnosis and testing can be obtained through your local or state health department or CDC.

Question:  What are the treatments for Parasites - Baylisascaris infection ?
Answer: No drugs have been shown to be totally effective for the treatment of Baylisascaris infection. Albendazole, a broad spectrum anthelmintic, has been recommended for specific cases.
    
Early treatment might reduce serious damage caused by the infection. Should you suspect you may have ingested raccoon feces, seek immediate medical attention.

Question:  What is (are) Parasites - Babesiosis ?
Answer: Babesiosis is caused by microscopic parasites that infect red blood cells. Most human cases of Babesia infection in the United States are caused by the parasite Babesia microti. Occasional cases caused by other species (types) of Babesia have been detected. Babesia microti is spread in nature by Ixodes scapularis ticks (also called blacklegged ticks or deer ticks). Tickborne transmission is most common in particular regions and seasons: it mainly occurs in parts of the Northeast and upper Midwest; and it usually peaks during the warm months. Babesia infection can range in severity from asymptomatic to life threatening. The infection is both treatable and preventable.
