Force of Infection and Evolution of Lesions of Canine Tegumentary Leishmaniasis in Northwestern Argentina Force of Infection and Evolution of Lesions of Canine Tegumentary Leishmaniasis in Northwestern Argentina Yearly incidence rates of 22.7% for seroconversion and of 13.5% for disease were calculated as indicators of the force of infection by this parasite upon the canine population. Alternatively, follow-up studies of canine populations determining the risk of acquiring infection in non-infected animals, the evolution of recent infection, and the outcome of incipient or advanced disease, are quite relevant for vaccination or therapy and have seldom been addressed in CTL. memorias.ioc.fiocruz.br /965/4155.html   (1425 words)

Force of infection - Wikipedia, the free encyclopedia In epidemiology, force of infection (denoted λ) is the rate at which susceptible individuals become infected by an infectious disease. Clearly, there are all kinds of practical difficulties with such a calculation, since not all new infections are reported, and it is often difficult to know how many susceptibles were exposed. The advantage of this method of calculating λ is that data on the average age of infection is very easily obtainable from doctors' reports, even if they are not reporting all cases of the disease. en.wikipedia.org /wiki/Force_of_infection   (292 words)

CDC - Infection Control in Home Care Infection surveillance, prevention, and control have constituted a discipline that has been acute-care based and oriented for the past 40 years. A scheme that includes probable home-care acquired infection (i.e., clinical signs and symptoms of pneumonia) as well as definite home-care acquired infection (i.e., confirmed by chest X ray and sputum culture) may be considered. In acute care, a patient's risk for nosocomial infection is related not only to the severity of illness and exposure to invasive interventions and devices but also to environmental risks, including exposure to other patients and inanimate reservoirs of nosocomial pathogens. www.cdc.gov /ncidod/eid/vol7no2/rhinehart.htm   (2767 words)

BioMed Central | Full text | Modelling the force of infection for hepatitis B and hepatitis C in injecting drug users ... This is defined as the instantaneous per capita rate at which susceptibles acquire infection and reflects the degree of contact with potential for transmission between susceptibles and infecteds[3]. The resultant force of infection estimates for both HBV and HCV were found to be lower than when test sensitivity is included in the model (results not shown). Previous authors have studied the incidence of infection in a cohort of IDUs [16] although to the authors' knowledge no previous studies have used this method of modelling to estimate the FOI for HBV and HCV in the IDU population. www.biomedcentral.com /1471-2334/6/93   (4423 words)

Endemic (epidemiology) - Wikipedia, the free encyclopedia In epidemiology, an infection is said to be endemic (from Greek en- in or within + demos people) in a population when that infection is maintained in the population without the need for external inputs. In this way, the infection neither dies out nor does the number of infected people increase exponentially but the infection is said to be in an endemic steady state. An infection that starts as an epidemic will eventually either die out (with the possibility of it resurging in a theoretically predictable cyclical manner) or reach the endemic steady state, depending on a number of factors, including the virulence of the disease and its mode of transmission. en.wikipedia.org /wiki/Endemic_(epidemiology)   (426 words)

Subject: HIV increasing among UK injection drug users To examine this futher, force of infection in and outside of London, defined as the yearly rate at which HIV-negative IDUs become HIV-positive, was estimated by fitting a model to prevalence data by calendar year and injecting career length. The results suggest that force of infection in London is higher amongst novice IDUs (those injecting for less than one year) and has increased over time. Between 1992-1997, the force of infection amongst novice IDUs in London was 0.008 (95% CI, 0.002-0.02), whereas between 1998-2003 it was 0.028 (95% CI, 0.016-0.045), or almost 3% per year. www.dpna.org /7ukaidsincrease.htm   (2157 words)

Technological Advances in Lighting and Booms for the OR: Impact on Infection Controland OR Efficiency Current clinical practices and procedures for surgical asepsis and the prevention of infection are based on the basic principles that the transmission of infection occurs by multiple methods. According to a 1992 study by a Surgical Wound Infection Task Force (comprised of members from SHEA, APIC, CDC, and SIS), the duration of a surgical procedure is a definite risk for procedure related infection(s). A prolonged surgical procedure may be an indicator of the complexity of the procedure, the expertise and skill of the surgeons, the extent of tissue trauma, or procedures that are not planned and coordinated among team members. www.infectioncontroltoday.com /articles/071feat4.html   (2062 words)

Chapter 9 The equality of these two statistics at low risks of infection and their correspondence to the causal model parameters is important to note since many times vaccine trials may be conducted in low risk settings. In some cases, such as enteric infections in developing countries, the force of infection can be very high and divergence of these two statistics could be quite large. Note that if the force of infection is high enough, vaccine efficacy calculated using the standard statistic will be quite close to zero even when a vaccine reduces the risk of transmission in a contact by 90% or more. www.sph.umich.edu /~jkoopman/802Web/Chap8.htm   (2124 words)

The transmission dynamics of influenza A at Hong Kong live bird markets The replacement rate at which the prevalence of infection is maximal depends on the number of contacts. If the infectious period is long while the infection potential is low, this could help in reducing the prevalence of infection, and it might even lead to local eradication. It is due to the fact that the reproduction number in Figure 3 refers to the invasion prospects of a pathogen in a population of susceptible individuals, while Figure 2 refers to the equilibrium prevalence. www.cvmbs.colostate.edu /aphi/isvee/vanBoven084.htm   (1088 words)

Howstuffworks "Boils: A Profile of a Skin Infection" A boil, or furuncle, is caused by a bacterial infection and irritation of the skin and its underlying structures. The same bacteria that cause the boil may also produce a toxin (poison) that causes blood clots, usually in the blood vessels that are around the boil. Squeezing may force the infection deeper into the skin and possibly into the bloodstream. health.howstuffworks.com /define-boils.htm   (838 words)

Howstuffworks "Ear Infections" Middle-ear infection (known medically as otitis media) is the most common illness in babies and young children. Adults are more likely to get an infection of the outer ear, which is aptly referred to as "swimmer's ear" because it usually gets its start when water containing bacteria or fungi seeps into the ear and gets trapped in the ear canal. Since middle-ear infections generally start with a cold or other upper respiratory infection, you'll help protect your child from ear infections by keeping him or her away from other kids who have infections. www.howstuffworks.com /how-to-care-for-your-ears3.htm   (1174 words)

Pediatric Advisor 2006.2: Colds For Teenagers A cold or upper respiratory infection is an infection of the nose and throat caused by a virus. Watch for signs of bacterial infections such as earaches, yellow drainage from the eyes, sinus pressure or pain (often indicating a sinus infection), or rapid breathing (often a sign of pneumonia). Sniffing and swallowing the secretions is probably better than blowing because blowing the nose can force the infection into the ears or sinuses. www.med.umich.edu /1libr/pa/pa_tncolds_hhg.htm   (822 words)

Population Health Metrics | Full text | The pre-vaccination regional epidemiological landscape of measles in Italy: ... [12]), a deeper investigation of spatial patterns of infection could reveal the existence of some between regions heterogeneity in age-related transmission rates that could be an indicator of a higher force of infection (or indeed perhaps suggest the presence of selective under-reporting by age). Estimates of EURO force of infection (FOI) and that from Italian case notifications; computations were based on standard techniques described by Anderson and May [9]. All "local" forces of infection are systematically substantially smaller compared to the EURO FOI, and surprisingly similar to each other in levels and shape: significant heterogeneity exists only in the youngest age groups. www.pophealthmetrics.com /content/3/1/1   (7178 words)

Dog medicine, dog herbs, vitamins,mineral supplements   (Site not responding. Last check: 2007-10-10) Ear infections are very common with dogs who have floppy ears although almost any breed of dog will have an ear infection from time-to-time. Dogs who have been administered antibiotics seem especially prone to chronic ear infections because the antibiotics will force the infections deeper and deeper into the body and the infections will reappear as the body tries to force the infection out. Experience has shown this natural remedy to aid in the healing of ear infections by increasing the amount of oxygen and enzyme activity within the ear itself. www.petmedicinechest.com /canine/earinfections.asp   (1061 words)

The time course of reported illnesses (epidemic curve) in the 1993 Milwaukee outbreak of cryptosporidiosis was analysed using a dynamic model considering time variant force of infection and incubation time distributions. Different functional forms for the force of infection and incubation time distribution were tested. These models gave a good fit to the data, although depending upon the functional forms of the underlying distributions, different incubation time and force of infection curves were obtained. www.iwaponline.com /jwh/002/jwh0020059.htm   (206 words)

MTV News | Task Force Recommends HIV Testing For All Pregnant Women Mother-to-child transmission of HIV affects more than 6,000 babies each year, the task force reported, and infection can take place during pregnancy (while in the womb), during labor and delivery (when the child can come into contact with the mother's infected bodily fluids), and after delivery, if the child consumes the infected mother's breast milk. In 1996 the task force recommended a strategy of routine counseling and screening for high-risk pregnant women, but recent evidence shows that prenatal counseling and HIV testing has gained wider acceptance among pregnant women, and that recommended treatment has been shown to significantly lower the number of women who pass HIV to their newborn. The task force also reaffirmed its original recommendation that all adolescents and adults at increased risk for HIV be screened for the virus. www.mtv.com /news/articles/1505223/20050705/index.jhtml?headlines=true   (497 words)

ASA November 1996 Newsletter [3] The Task Force on Infection Control of the ASA Committee on Occupational Health of Operating Room Personnel felt that an early notice of these events would be beneficial to anesthesiologists. The results of the case control study suggested that "the risk for HIV infection among HCWs who used ZDV (as prophylaxis after occupational HIV exposure) was reduced by approximately 79 percent."[3] While the study is not without flaws, it also better established risk factors for HIV infection. In many hospitals, the local infection control staff/committee already has reviewed this material, and there may be a hotline or a procedure in place to respond quickly to a needlestick incident. www.asahq.org /Newsletters/1996/11_96/Article1.html   (1917 words)
