Sometimes symptoms begin as early as on the plane ride home, sometimes not until weeks later. In either case, the patient becomes progressively ill, critically so, all the while unknowingly infecting others. The disease spreads, chaos is loosed, and only the timely insight of an awkwardly introverted yet surprisingly attractive physician stands between armageddon and the return of normalcy. Nonetheless, the likelihood of today’s critical care physician having to manage patients with a tropical infection is increasing, as international travel has increased from an estimated 25 million border crossings in 1950 to over 806 million crossings in 2005 (1). To better prepare travelers prior to their trips abroad, the discipline of travel medicine has been refined over the past 25 years, with an increasing reliance upon evidence-based data and the recent publication of practice guidelines (2). This information assists the physician in determining not only what vaccines or prophylactic regimens may help prevent infection in the traveler, but also stresses the importance of safety awareness and environmental risk avoidance. It is no surprise, then, that each year four million travelers returning from developing countries become ill enough that medical intervention is required either en route or upon return home (4). That is not to say there are four million cases of Ebola or African trypanosomiasis every year, but how can the clinician know what illnesses are being seen, and more importantly, which to consider more likely in their patients? Established in 1995, it now comprises 41 travel or tropical medicine clinics (16 in the United States, 25 in other countries representing all continents) that not only report what diagnoses are seen in their facilities, but additional invaluable data such as time to presentation of illness, geographic exposures, adherence to prophylactic measures, etc. With now more than a decade of surveillance information available, it has been shown that febrile illness, dermatologic disorders (especially insect bites), and acute/chronic diarrheal illnesses comprise almost 70% of all travel-related illness (4). An analysis of 6957 travelers with fever revealed that malaria (21%), acute diarrheal disease (15%), respiratory illness (14%), and dengue (6%) were the most commonly identified etiologies (6). Time to presentation can be helpful to the clinician when generating a differential diagnosis (see Table 1). It is helpful to realize that the familiar adage “common things are common” applies also to travel medicine. In a review of 25,023 patients within the GeoSentris database, there were no reported cases of travel-related anthrax, yellow fever, primary amebic meningoencephalitis, poliomyelitis, Rift Valley fever, tularemia, murine typhus, tetanus, diphtheria, rabies, Japanese encephalitis, or Ebola (4). In the same report, of 17,353 patients, only one case each of the following infections was identified: Angiostrongylus cantonensis, hantavirus, cholera, melioi- dosis, Ross River virus, legionellosis, meningococcal meningitis, and African trypanosomiasis. If any of these diagnoses is suspected, an infectious diseases consultation is recommended. As malaria is the single most common life-threatening infection in returning travelers (Table 2), it will be emphasized in this chapter. Other critical care infectious disease syndromes to be Table 2 General Considerations in Potentially Infected Critically Ill Returning Travelers Diagnostic consideration Comments Make accurate traveler- and itinerary-specific Obtain detailed history of sites visited, activities, and potential risk assessment. Incubation periods: short (<10 days); intermediate (10–14 days); prolonged (>21 days) A minimum period of 5–7 days before considering malaria. Narrow the differential diagnosis using clinical progression and specific findings (i. Always consider and perform diagnostic testing to evaluate for malaria if a traveler has been in a malarious region with an appropriate incubation period. Data from 1997–2002 collected through the GeoSentinel global sentinel surveillance identified malaria in 3. Patients with falciparum malaria were more likely to have traveled to sub-Saharan Africa (89%), with the majority (80%) presenting within four weeks of their return. Several important features are noted among those patients who died from their infection. These include: insufficient or inappropriate malaria chemoprophylaxis (90%) and delay in diagnosis and/or effective therapy (40%). Deaths were considered preventable in 85% of cases and were commonly attributed to patient-related decisions/actions and/or contributing medical errors (11). The current recommendations for malaria prophylaxis take into consideration regional antimalarial drug resistance (13). And so, as a result of our population’s increasing travel to malaria-endemic areas as well as oftentimes inadequate adherence to prescribed chemoprophylaxis, it is increasingly likely that today’s critical care physician will encounter patients with malaria. Unfortunately, there are no historical or physical findings pathognomonic for malaria. Therefore, malaria cannot be ruled out by history or physical examination alone (11,19,20).
Essential features are: 1) examining a high percentage of the population through ﬁeld surveys; 2) extending treatment of active cases to family and community contacts based on the demonstrated prevalence of active yaws; 3) surveys at yearly intervals for 1–3 years generic hyzaar 50mg on-line, as part of the established rural public health activities of the country generic hyzaar 12.5 mg otc. Disaster implications: None observed, but potentially a risk in refugee or displaced populations in endemic areas without hygienic facilities. International measures: To protect countries against risk of reinfection where active mass treatment programs are in progress, adjacent countries in the endemic area should institute suitable measures against yaws. Movement of infected people across frontiers may require supervision (see Syphilis, section I, 9E). Identiﬁcation—Acute infectious viral disease of short duration and varying severity. The mildest cases may be clinically indeterminate; typical attacks are characterized by sudden onset, fever, chills, headache, back- ache, generalized muscle pain, prostration, nausea and vomiting. The pulse may be slow and weak out of proportion to the elevated tempera- ture (Faget sign). Some cases progress after a brief remission of hours to a day into the ominous stage of intoxication manifested by hemorrhagic symptoms including epistaxis, gingival bleeding, hemateme- sis (coffee-ground or black), melaena, and liver and renal failure; 20%–50% of jaundiced cases are fatal. The overall case-fatality rate among indigenous populations in endemic regions is 5% but may reach 20%–40% in individual outbreaks. Serological diagnosis includes demonstrating speciﬁc IgM in early sera or a rise in titre of speciﬁc antibodies in paired acute and convalescent sera. Recent infections can often be distinguished from vaccine immunity by comple- ment ﬁxation testing. Infectious agent—The virus of yellow fever, of the genus Flavivirus and family Flaviviridae. Occurrence—Yellow fever exists in nature in 2 transmission cycles, a sylvatic or jungle cycle that involves Aedes or Haemagogus mosquitoes and nonhuman primates, and an urban cycle involving humans and mainly Aedes aegypti mosquitoes. Sylvatic transmission is restricted to tropical regions of Africa and Latin America, where a few hundred cases occur annually, most often among occupationally exposed young adult males in forested or transitional areas of Bolivia, Brazil, Colombia, Ecuador and Peru (70%–90% of cases reported from Bolivia and Peru). Historically, urban yellow fever occurred in many cities of the Americas; no outbreak of urban yellow fever has occurred for 50 years in North America. There is no evidence that yellow fever has ever been present in Asia; in western Kenya, sylvatic yellow fever was reported in 1992–1993. Reservoir—In urban areas, humans and Aedes mosquitoes; in forest areas, vertebrates other than humans, mainly monkeys and possibly marsupials, and forest mosquitoes. Transovarian transmission in mosqui- toes may contribute to maintenance of infection. Humans have no essential role in transmission of jungle yellow fever, but are the primary amplifying host in the urban cycle. Mode of transmission—In urban and certain rural areas, the bite of infective Aedes mosquitoes. In South American forests, the bite of several species of forest mosquitoes of the genus Haemagogus. Period of communicability—Blood of patients is infective for mosquitoes shortly before onset of fever and for the ﬁrst 3–5 days of illness. The disease is highly communicable where many susceptible people and abundant vector mosquitoes coexist; it is not communicable through contact or common vehicles. Susceptibility—Recovery from yellow fever is followed by lasting immunity; second attacks are unknown. Transient passive immunity in infants born to immune mothers may persist for up to 6 months. Preventive measures: 1) Institute a program for active immunization of all people 9 months or older who are exposed to infection because of residence, occupation or travel. Antibodies appear 7–10 days after immunization and may persist for at least 30–35 years, probably much longer, though immunization or reim- munization within 10 years is required by the International Health Regulations for travel from endemic areas. The vaccine can be given any time after 6 months of age and can be administered with other antigens such as measles vaccine. The vaccine is contraindicated in the ﬁrst 4 months of life and should be considered for those aged 4–9 months only if the risk of exposure is judged to exceed the risk of vaccine-associated encephalitis, the main complication in this age group. The vaccine is not recommended in the ﬁrst trimester of pregnancy unless the risk of disease is believed to be higher than the theoretical risk to the pregnancy. There is no evidence of fetal damage from the vaccine, but lower rates of maternal seroconversion have been observed, an indication for reimmunization after delivery or termina- tion. Protective clothing, bednets and repellents are ad- vised for those not immunized. Control of patient, contacts and the immediate environment: 1) Report to local health authority: Case report universally required by International Health Regulations; Class 1 (see Reporting).

In this business model generic 50mg hyzaar, Government does not make an outright purchase of capital equipment for a dialysis clinic and instead generic 50 mg hyzaar with visa, Government enters into a contractual agreement to lease its capital equipment requirements to private hemodialysis provider company or patient brings his own dialysis disposables. During the contractual period, Government purchases its dialysis consumable requirements exclusively from private partner. There has to be a fixed term of payment to private partner, say every month or say 30 day. The concept is to set up a chain of dialysis centers that would have a non nephrologist dialysis trained physician present at the centre round the clock. A tie up could be made with identified agency for provision of services including equipments, manpower and consumables etc. There would be one standalone dialysis centre operationalised in 100 districts with private public partnership. States would be encouraged to have dialysis facilities through decentralized National Rural Health Mission planning. The average cost of dialysis in Delhi is as follows: Item Cost Average cost of Dialysis 1000 Per dialysis cost for Haemo dialyser ( 600 for 4 time use) 150 Haemodialysis fluid used in each dialysis 200 Saline drip used in each dialysis 100 Inj. Heparin in each dialysis 50 Total cost of Each dialysis 1500 Cost of investigations and medicines 600 Total cost per dialysis including investigations & medicines 2100 121 Till the time dialysis facilities are developed, chronic kidney patients who are below poverty line would be paid for dialysis on per case basis. Reputed large Hospital in the region would be taken on retainership basis and paid per case basis. For this purpose if 1000 dialysis per month are to be supported the expenses would be about Rs. This model would be shifted to private public partnership wherein 1000 dialysis per month per centre would be assured. While former will need lifestyle modification, behavioral changes, improved information campaign and pharmacological interventions etc. Deceased Organ Retrieval is going to be main area for improving supply, although living organ transplant particularly for kidney and to some extent for liver needs to be continued. More dialysis centres and its staff, transplant centre with transplant surgeons and nurses will build up the capacity of improved services. Free or subsidized diagnostic services & immuno-suppressive drug supply for the poor and needy will ensure better compliance and outcome of transplant services. Post-transplant services to transplant recipients and living donors Strategies: • Enhancing the facilities for organ transplantation throughout India • Establishing network for equitable distribution of retrieved deceased organs. Objectives: • To organize a system of organ procurement & distribution for deserving cases for transplantation. Each zonal unit would look after few hospitals in their respective jurisdiction for organ retrieval/transplantation. One new transplant centre would be established and one would be strengthened in Govt. A co-ordination committee could be formed to look into the actions and co-operation required from various ministries and departments. National and regional workshops on issue of organ transplantation would be carried out with purpose of advocacy at all levels for various stakeholders. Certificate of recognition to the donors will be given by the transplant centre on behalf of the appropriate authority. Steps would be taken to make provision for diagnostic tests at affordable and subsidized cost to the transplant recipients and donors patients in the public sector health care delivery system. Free annual health check to living donor & free treatment of all donor related complications would be promoted. Financial assistance for immunosuppressant drugs has also been kept separately which would benefit about 5000 patients every year @ Rs. Establishing 10new facilities for Kidney & 2 new for liver Transplantation in Govt. Strengthening of 10 existing kidney & 2 existing liver transplantation facilities in Govt. Training retrieval team members, transplant surgeon, dialysis physician, nurse, grief counselor, coordinator and dialysis technician through a structured programme. To undertake activities related to policy/programme correction as & when required. To start scheme for promoting/facilitating deceased donation & protecting donors/transplant surgeons. Financial assistance to patients for maintenance therapy of immunosuppressive drugs. Scheme for promotion of organ donation/ protecting donor’s health/ protecting transplant surgeon/protecting vulnerable poor. It would have cell for kidney, liver & heart organs, dealing with policies, quality control etc. In States of bigger size, even 2-3 zonal centers will be established in next five year plan. Each zonal center would look after 1-2 hospitals in their respective jurisdiction for organ retrieval/transplantation during current plan.
