35 terms
Terms | Definitions |
|---|---|
 Hepadnavirus | inflammation of liver (hepatitus), jaundice; yellow skin, brown urine (due to blood) |
| HAV Hepatitis A Virus | fecal/oral means, no long term liver damage, no trmt, vaccine available |
| HBV Hepatitis B virus | blood/body fluids transmission, long term liver damage; causes chronic liver disease or liver cancer. Concern for health care b/c can live in dried blood for up to 7 days; causes infection if comes in contact with broken skin. |
| HCV Hepatitis C virus | transmission by blood exposure, blood transfusion (donor blood) = most common way of getting infection, risk of LT liver damage, no vaccine |
| HDV Hepatitis D virus | transmission by exposure to blood or body fluids, requires co infection with Hep B, severe LT or permanent liver damage, usually seen with HIV patients |
| HEV Hepatitis E virus | fecal/oral transmission, endemic-associated with poor hygiene/sanitation; in Central Asia, Middle East, parts of South America & Africa. |
| Herpes Virus group | Group of 8 viruses, dormant stage (shows latency by reemerging) in human body, leads to relapse due to UV light (going to the beach), injury to area, fever, stress, immocompromised patient |
| HSV1 Herpses Simplex Virus 1 | Location of infection = oral lesions in mouth, fever blisters,cold sores..90% of population infected, no treatment. Risk of herpetic whitlow --> health care worker who handles oral secretions with no gloves on fingers...lesions appear on fingers |
| HSV2 Herpes Simplex Virus 2 | Location: gential; internal/external, thighs & buttocks. Characteristic symptom: lesions (blisters). Condoms dont protect, 20% of population infected. |
| EBV Epstein-Barr Virus | mononucleosis; transmitted by saliva, 'kissing disease.' Charateristic symptom: sleepiness, 16-20 hoours; No trmt - self limiting; Heterophile antibodies found in blood, attacks myalin sheath of spical cord. Can lead to CFS (chronic fatigue syndrome), Burkitts Lymphoma(cancer of lymph nodes), MS (multiple sclerosis) |
| VZV Varicella-Zoster Virus | Primary infection = Chicken Pox -- rash on face, scalp, trunk. Re-emerges as: Shingles (>65 y.o. or cancer, HIV), Bells Palsy (temporarily paralyzed facial muscles). Also: Reyes Syndrome possible w/aspirin: affect CNS - causes personality change, irritability, compativeness, confusion... or cause Death |
| HPV Human Papilloma Virus | most common STD, causes gential warts and cancer. < 25 y.o. = 50%...by 50 y.o. = 80%. Treat c cryosurgery (freezing). Vaccine: Gardasil for 13-26 y.o., condoms do not prevent infection. |
| Parvovirus B19 | 5ths disease (5th in the line of red rashes); Characteristic symptom: slapped cheek appearence. Complication in adults: extreme joint pain for several weeks; No trmt--self limiting. |
| Variola Virus | Small Pox, lesions, unique rash: bb's under skin with dimple on top, last seen in 1977, used for bio terrorism c Native Americans. |
| HIV Human Immunodeficieny Virus | Type 1 and 2: Type 1 is more common. Cell infected: T-helper, diagnose c blood test--> c HIV screen, takes 1-3 mo to produce antibodies if + do a Western Blot to confirm. Infection = AIDs; <200 CD-4 cells causes AIDS, virus converts RNA to DNA. Treatment: Antiviral therapy to slow the progress of Aids, goal is to keep CD4 levels up, most common drugs: AZT aka "Hell in a Bottle" and Protease Inhibitors--enzyme to stop reverse transcriptase; use Combo drugs = "cocktail" Can have HIV and not have AIDs (the disease part) for decades. HIV virus mutates many x/day and will mutate over a 100 million times by the end of the infection. |
| Polio Virus | fecal/oral and fly transmission by contimated food/water, infects spinal cord (CNS); Vaccine: Salk injection & Sabin oral dose |
| Arboviruses | athropod-borne virus, caused by vectors: ticks, fleas, mozquitoes & flies. Found in warm climates. |
| Yellow Fever Virus | Mosquitos; Causes yellow fever; Characteristic symptom: jaundice, brown urine, plasma. Vaccine available. Relevance to PA: 1793 the Capital of PA moved from Phili to Hbg due to an outbreak. |
| Dengue Fever Virus | Mosquitos; Causes breakbone and blackwater fever, Characteristic symptom: severe pain in muscles & joints; black or red stool, jaundice. |
| WNV West Nile Virus | Transmitted by mosquitos; Reservoirs = birds, horses or people; Causes West Nile Vile; Characteristic symptom = encephalitis; No vaccine. |
| Influenza Virus Type A | H1N1- swine flue & H5N1- avian flue (bird flu)..H1N1 leads to pneumonnia and cause death; Complication = Gullian-Barre syndrome. No trmt-self limiting. |
| RSV Respiratory Synctial Virus | viral resp disease in children,lead to lifelong asthma |
| RhinoVirus | common cold, no abs destroy NF |
| Coronavirus | SARS |
| Rubeola Virus | severe measles infection, flat spread rash, Kopliks spots in mouth,spread respiratory |
| Rubella Virus | mild form of measles, rash, unborn fetus |
| Mumps Virus | salivary glands, replication of virus in other organs, big cheeks |
| Coxsackie Virus | ulcers, lesions in mouth, rash on soles of feet and palms of hand,, very contigous |
| Rotavirus | stomach flu in children, vomit and diah, fluid.electorye replacement |
| Norwalk/Norovirus | stomach flu in adults, cruise ships, aerolization of vomit |
| Hantavirus | mouse urine and dropping, mouse deer, Southwest Us, chest pain-death |
| Ebola Virus | africa, hemorrgage fever-bleeding in every opening (DIC) |
| Rabies Virus | saliva of animals, raccoons, salivation, lyssavirus, CNS effected |
| Prion Proteinaceous infectious particle | brain, no nucleic acids compared to virus, control is to burn, kuru, scrapie, bovine encephlitis |
| Cancer causing viruses | EBV HBV, HPV HTLV, virus turn genes on and off effection the immune system and other celluar process, burkitts lyphoma, liver, cercical, leukemia |
