Epidemiology Paper On Influenza

We have shown an increase in emergence of aivs infecting humans in the last decade. However, only of the 335 identified global eid events was an influenza a virus (the h5n1 subtype). Nrs nrs-429vn- - summer 2016 nursing nrs-427v-0 - fall 2015 nrs 427 v nrs 427 v - fall 2014 nrs 427vn - fall 2016 nrs 427vn - winter 20spring 2016 as a current student on this bumpy collegiate pathway, i stumbled upon course hero, where i can find study resources for nearly all my courses, get online help from tutors 247, and even share my old projects, papers, and lecture notes with other students.

I cannot even describe how much course hero helped me this summer. Epidemiological features of reported outbreaks or isolate cases of distinct avian influenza serotypes. Following the expansion of the poultry industry from the mid-1980s (particularly in china and some other asian countries) a broad range of aiv lineages have evolved to circulate among domestic poultry species.

After the first zoonotic aiv human infection was reported in the us in 1979, emergence of zoonotic aivs have been reported from the us and canada (   2) and from 2013, all novel aivs have emerged in different geographic regions in china ( human infections which have been associated with animal environments have been predominantly linked to a production animal species (mostly swine or avian), whilst infections caused by exposure to pets, wild animals, or laboratory animals have rarely been documented. Mild illness is associated with infections in children mild illness was seen for most h9n2 infections (which has a young average age of infection in humans) and for the only two cases of young children infected with h5n6 (aged 5 and 11). All were caused by subtypes other than hpai h5n1.

Prior to the emergence of h5n1 in the 1990s, all other aiv strains which caused severe outbreaks in poultry were able to be eliminated through standard control measures. Bethmont a, bui cm, gardner l, sarkar s, chughtai aa, macintyre cr. Highly pathogenic (hpai) outbreaks in poultry typically cause acute, severe mortalities and have significant economic implications due to the severe control measures (e.

. It is critical to target control measures in regions with high poultry population growth to prevent corresponding growth of aiv reservoirs in this host population. For h7n9 as well, young children presented with only mild infections, with more severe disease seen in older adults.

H7n9 infections were mainly identified or reported during winter months in 20 most infections (51 and 32 respectively) occurred in january, in 2015 most infections (42) occurred in february, however in 2013 most infections (64) occurred in april (early spring) most zoonotic aivs (6 of 10) and all 3 swine influenza variants typically cause mild infections in humans (see table  ). Its truly become something i can always rely on and help me. Quantified degree of poultry exposure differs for human cases of avian influenza h5n1 and h7n9. However, china is the largest global producer of swine (the us is the second largest producer). Each point indicates a distinct avian influenza serotype known to have caused human infection, placement of point corresponds to their year of emergence.

    These events indicate a need to re-evaluate where risk of zoonotic aiv emergence is likely. However there are few incidences of larger scale outbreaks which have presented with more cases than would be expected in sporadic transmission (i) large numbers of h7n9 human cases have occurred each year since its emergence in 2013 (159 cases in 2013, 334 cases in 2014, 210 cases in 2015 and 99 cases in 2016 , (ii) the h5n1 outbreak in egypt from 2014 to 2015 which caused 114 cases , and (iii) h7n7 outbreak in the netherlands in 2003 which caused 89 cases.

    H7n9 infections were mainly identified or reported during winter months in 20 most infections (51 and 32 respectively) occurred in january, in 2015 most infections (42) occurred in february, however in 2013 most infections (64) occurred in april (early spring) most zoonotic aivs (6 of 10) and all 3 swine influenza variants typically cause mild infections in humans (see table  ). A systematic review of the comparative epidemiology of avian and human influenza a h5n1 and h7n9 - lessons and unanswered questions. In the end, i was not only able to survive summer classes, but i was able to thrive thanks to course hero. Advances in influenza diagnostics and surveillance capabilities, as well as increased clinician awareness (particularly following the emergence and continued seasonal occurrence of h7n9), have likely contributed to better ascertainment of influenza a in humans in china. Low-income countries which are undergoing rapid commercialisation of their poultry sector are at highest risk of harbouring aivs, and are unlikely to detect nor adequately control aiv spread.

    In the past 5 years alone, 4 novel subtypes and 3 novel variant strains have emerged in humans. We previously compared the novel h7n9 which emerged in humans in shanghai, 2013 to the more extensively studied h5n1 and highlighted some puzzling differences in the epidemiology influenza a serotypes known to cause human infections. I was behind on tulane coursework and actually used uclas materials to help me move forward and get everything together on time. After the first zoonotic aiv human infection was reported in the us in 1979, emergence of zoonotic aivs have been reported from the us and canada (   2) and from 2013, all novel aivs have emerged in different geographic regions in china ( human infections which have been associated with animal environments have been predominantly linked to a production animal species (mostly swine or avian), whilst infections caused by exposure to pets, wild animals, or laboratory animals have rarely been documented. Numbers of human cases and deaths are total global counts or estimates. The increase in aiv emergence in humans may also be a reflection of increased aiv persistence and diversity in poultry. Research interests include zoonotic diseases and geospatial analysis. Zoonotic aiv infections have been sporadically reported in developed regions such as north america, europe and australia, with the most recent report occurring in 2013 in italy. The aim of this report is to identify trends or changes in the epidemiology and characteristics of zoonotic influenza a emergence in humans over time. We searched publications using the scopus database, and grey literature using the world health organisations (who), centres for disease control and prevention (cdc), flutrackers and promed websites, using the subtype as the keyword.

    Reduction of these natural habitats for wild birds and can result in birds using agricultural or urbanised areas, promoting interaction with high density farming systems (such as poultry and swine), and also humans. The authors compiled a comprehensive listing of all eid events in humans from 1940 to 2004 to identify drivers of infectious disease emergence. Increasing urban and agricultural encroachment into previously uninhabited areas, particularly in developing countries, may also play a role in promoting aiv transmission to humans and domestic animals from wild bird reservoir hosts. After the first zoonotic aiv human infection was reported in the us in 1979, emergence of zoonotic aivs have been reported from the us and canada (   2) and from 2013, all novel aivs have emerged in different geographic regions in china ( human infections which have been associated with animal environments have been predominantly linked to a production animal species (mostly swine or avian), whilst infections caused by exposure to pets, wild animals, or laboratory animals have rarely been documented Buy Epidemiology Paper On Influenza at a discount

    We extracted information on year and country of incidence, characteristics of persons affected (sex, age, occupation), clinical signs, mortalities, details of animal exposure and pathogenic classification of virus. We recommend pandemic preparedness measures focus on preventing zoonotic disease emergence, specifically the strengthening of control efforts to reduce (i) potential introductions of aivs into poultry populations, (ii) subsequent spread within the poultry sector, and (iii) virus transmission at the human-animal interface (particularly within lbms). A recognised caveat however is the under ascertainment of subclinical cases predominantly, only patients with signs and symptoms, or severe disease, present to the health system and a large proportion of cases with subclinical infection may remain unreported Buy Online Epidemiology Paper On Influenza

    In recent years novel reassortant influenza a viruses have emerged h5n6 in 2014, h7n9, h10n8 and h6n1 in 2013, and a novel h1n2 swine-flu variant in 2012. Reduction of these natural habitats for wild birds and can result in birds using agricultural or urbanised areas, promoting interaction with high density farming systems (such as poultry and swine), and also humans. In the latter case, a history of incidental poultry contact (such as walking through lbms) is more common all zoonotic influenza infections have typically occurred infrequently, in a sporadic pattern typical of animal to human transmission without sustained human to human transmission ensuing. A total of 14 different ha-na combinations are known to cause human infections, with h1n1, h1n2, and h3n2 ha-na combinations emerging multiple times since 1918 (table  swine influenza variant viruses (h3n2v, h1n1v, h1n2v,) have all emerged in humans in the united states (us) in july 2011, december 2011 and june 2012 respectively (see table  ), and subsequent occurrences have largely been restricted to the us and canada Buy Epidemiology Paper On Influenza Online at a discount

Of these, 6 strains are able to be efficiently transmitted from human-to-human, 10 are predominantly zoonotic aivs, and 3 are predominantly zoonotic swine influenza variants. Communicable diseases make up a big part of the healthcare community. However, the pandemic which emerged in 2009 was a completely different virus, unrelated to h5n1. Research interests include zoonotic diseases and geospatial analysis.

    We find there have been recent increases in the number of reports of aivs infecting humans, predominantly from mainland china. Bethmont a, bui cm, gardner l, sarkar s, chughtai aa, macintyre cr. A bias in the reporting of severe cases indicates that our reported cfrs are likely to be inflated. However, china is the largest global producer of swine (the us is the second largest producer). Numbers of human cases and deaths are total global counts or estimates.

Such close interactions increase the risk of aiv introduction, and zoonotic disease transmission we recommend aiv control programmes in focus on preventing such interactions particularly in african and asian countries which are urbanizing rapidly For Sale Epidemiology Paper On Influenza

    Davis-Moore Thesis Of Social Stratification

    Aiv transmission in domestic pets are considered to be rare, mild and unsustainable however in november 2016, lpai h7n2 was found to cause an outbreak in 45 domestic kittens causing one fatality. A good example is the efforts in pandemic planning globally around h5n to 2009, which assumed the next pandemic would be h5 related. Such close interactions increase the risk of aiv introduction, and zoonotic disease transmission we recommend aiv control programmes in focus on preventing such interactions particularly in african and asian countries which are urbanizing rapidly.
