Chikungunya Fever A Review Of The Literature Biology Essay

The Newala and Masasi Districts of the Southern Province, Tanzania, reported its first dengue-like eruption in 1952-1953, on the footing that this epidemic involved enfeebling joint strivings and shorter incubation period, thereby excepting dandy fever ( Robinson 1955 ) . The infection was called chikungunya ; a word from the Makonde idiom depicting patient ‘s writhed position ( Lumsden 1955 ) . Chikungunya is an arthropod borne virus ( arborvirus ) of the genus: Alphavirus from Togaviridae household. It is transmitted to worlds chiefly by the twenty-four hours seize with teething mosquito species Aedes aegypti and Aedes albopictus ( Townson and Nathan 2008 ) . Furthermore, Aedes aegypti eggs collected from the Tanzanian eruption were used for the first isolation of Chikungunya virus ( CHIKV ) ( Ross 1956 ) . CHIKV contains a positive-sense individual stranded RNA genome, enclosed in an icosahedral nucleocapsid, all enclosed in a phospholipid bilayer envelope. Embedded in the envelope are multiple transcripts of two encoded glycoproteins E1 and E2, a little glycoprotein E3, and a hydrophobic peptide 6K ( Strauss and Strauss 1994 ) . However, the functions of these glycoproteins are non elucidated, but it can be assumed that it could ease the fond regard of the virus to host cell.


Subsequent to the Tanzanian epidemic, several eruptions have been reported worldwide, including the Indian Ocean Islands ; La Reunion ( Renault et al. 2007 ) , Mayotte ( Sissoko et al. 2008 ) , and the Maldives ( Yoosuf et al. 2008 ) . There were eruptions whereby Chikungunya had concurrency with other infections ; with Dengue ( Ratsitorahina et al. 2008, Yoosuf et Al. 2008 ) and with Plasmodium falciparum infection ( Pastorino et al. 2004 ) . Furthermore, Chikungunya have been imported into several European states ; United Kingdom ( HPA 2007 ) , France ( Hochedez et al. 2007 ) , Germany, Switzerland, Denmark, Poland ( Paning et al. 2008 ) , with Italy witnessing its first CHIKV eruption in 2007 ( Rezza et al. 2007 ) .

Aim of reappraisal

The Italian eruption has demonstrated that merely one viraemic individual was required to incite an eruption and due to increased population motion worldwide, CHIKV could widen to pandemic proportions ( Rezza et al. 2007 ) . Furthermore, the eruptions could hold been underestimated due to its concurrency with other infections. Therefore, this literature reappraisal will show to the reader that the Western medical specialty should be be aftering for CHIKV eruptions which are going progressively possible due to universe clime alteration.

Clinical Features

Chikungunya is a mild and self restricting infection ( Rezza et al. 2007 ) with incubation period of 2-7 yearss ( Robinson 1955 ) . Patients normally presents with a figure of clinical characteristics, with febrility, weariness, joint hurting, anorexia, and nausea presenting as common clinical characteristics ( Table 1 ) . Arthalgia and myalgia chiefly involves the appendages of carpuss, mortise joints, custodies, pess and phalanges, while skin roseola and petechiae are manifestations of bleeding ( Kannan et al. 2009 ) . During the La Reunion eruption, G & A ; eacute ; raldin et Al. ( 2008 ) observed perpendicular transmittals from female parent to child, with neonates showing with chikungunya infection without anterior mosquito bites. These newborns became diagnostic between 3-7 yearss postpartum, with presentation of febrility, hurting, hapless eating, disseminated intravascular curdling ( DIC ) with GI and intellectual hemorrhage, petechiae, and distal articulation hydrops. Encephalitis, thrombopenia and hemorrhagic febrility were presented as terrible neonatal infections ; nevertheless, no human deaths were reported ( G & A ; eacute ; rardin et Al. 2008 ) .

Transmission of CHIKV

CHIKV requires two types of hosts to finish its reproduction rhythm. First, Aedes mosquito species transmits the virus to animate beings, and act as unequivocal hosts. Second, worlds and other animate beings become septic with the virus and act as intermediate hosts. The transmittal between the natural hosts ( Primatess, birds, gnawers and others ) and the unequivocal hosts involves the sylvatic ( chief ) rhythm ( Pardigon 2009 ) . By interrupting this rhythm, worlds became incidental hosts, ensuing in urban transmittal rhythms giving epidemics. These worlds could convey CHIKV straight to domestic mosquitoes ( Gould and Higgs 2009 ) and indirectly to domestic animate beings such as poultry, pigeons and caprine animals ( Lumsden 1955 ) . When an Aedes mosquito ingests viraemic blood repast, CHIKV replicates in the salivary secretory organs and ovaries, sites where it can be excreted. Upon another blood repast, the mosquito injects the viraemic spit into a susceptible host. Contrary, within the ovaries, CHIKV is transmitted to the mosquitoes ‘ eggs by perpendicular transmittals ( Figure 1 ) . The dried-out nature of these eggs enables it to last longer periods in the environment, where they are hatched during the rainy season ( Gould and Higgs 2009 ) .

Distributions of Aedes albopictus and Aedes aegypti

Aedes aegypti was the prevailing vector during earlier eruptions in Africa ( Lumsden 1955 ) , and it has been implicated in some recent eruptions in Africa ( Gould et al. 2008 ) and Indonesia ( Laras et al. 2005 ) . However, Aedes albopictus have been described as the chief vector implicated in a figure of recent eruptions, between 2005 to 2007 ( Leroy et al. 2009, Pag & A ; egrave ; s et Al. 2009, Ratsitorahina et Al. 2008, Renault et Al. 2007, Sissoko et Al. 2008 ) . In the Gabonese eruption affecting both vectors, Vazeille et Al. ( 2008 ) hypothesised that Aedes albopictus is a more suited vector for CHIKV than Aedes aegypti, as it has a higher susceptibleness for the virus. The two vectors have been recovered from several engendering sites with some convergences ( Table 2 ) . Surs have been the chief beginning of Aedes albopictus larval importing into Italy, in 1992, from Atlanta, USA. Consequently, the trade of these used Surs within Italy had caused big infestations of Aedes albopictus in Linguria, Veneto, Lombardy and Eimlia-Romagna parts, by the terminal of 1995 ( Knudsen et al. 1996 ) . Aedes aegypti larvae predominate inside place, whereas Aedes albopictus larvae predominate outside place ( Preechaporn et al. 2006 ) .

Consequence of clime alteration

Outbreaks have been associated with climatic conditions such as temperatures and high rainfall. Temperatures influence the developmental rate of Aedes albopictus larvae to grownup mosquitoes, with the rate optimizing at temperatures between 25 to 30oC ( Straetemans 2008 ) . Therefore, Tilson et Al. ( 2009 ) argued that average monthly temperatures above 20oC are required to originate an eruption, as illustrated by the Italian eruption that was initiated in June and subsided in September when the monthly mean temperatures were 22oC and fell below 20oC. Average one-year rainfalls over 500mm is required ( Straetemans 2008 ) to supply suited genteelness environment for the mosquitoes to spread out their population ( Lumsden 1955 ) ; as a consequence, most eruptions have been associated with high rainfall ( Lumsden 1955, Pastorino et Al. 2004, Renault et Al. 2007, Sissoko et Al. 2008, Yoosuf et Al. 2009 ) as illustrated in Table 3. In 2009, the UK Met office ( 2010 ) recorded a average one-year rainfall and temperature of 1201.3mm and 9.2oC, severally. The rainfall is sufficient to originate an eruption ; nevertheless, the low temperature is deficient to back up the mosquitoes ‘ life rhythm. Therefore, the inquiry is what would the impact be to the UK if the climatic status alterations to favor this mosquito?

Distribution of Chikungunya eruption

Mayotte ( Gallic Overseas Territory ) , an island of the Comoros archipelago, encountered its first CHIKV eruption imported from Grand-Comore in mid-April 2005 ( Renault et al. 2007 ) , with 6346 reported instances ( in two moving ridges ) , observed by the surveillance system implemented throughout the island by the local Gallic Health Authority, Dass ( Direction des intimacies sanitaires et sociables ) Mayotte. The first ( minor ) wave commenced in April 2005, it subsequently peaked in hebdomad 18 and the infection rate diminished in June, with the virus keeping low degrees thenceforth, during the temperate and dry season. However, the second ( major ) wave began during the first hebdomad of May 2006, peaked during the hottest and showery months around March/April 2006 and reduced to command degrees by July 2006 ( Sissoko et al. 2008 ) .

In March 2005, a chikungunya infection which started in Grande-Comorre was imported into La Reunion ( Gallic Overseas Territory ) , going its first terrible reported instance affecting two moving ridges of eruption, as observed by the epidemiological surveillance system implemented by the island ‘s local Health Authorities ( Renault et al. 2007 ) . First, a ( minor ) wave commenced in March 2005, peaked in May 2005 and decreased at the beginning of July to about 100 instances where the degree was maintained during the austral winter. By December 2005 the second ( major ) wave began ; nevertheless, the capacity of the surveillance system at the clip was deficient to measure the figure of instances, as the figure of instances was increasing exponentially. This resulted in an underestimate of the figure of reported instances with possible misdiagnosis with Dengue febrility which circulated the island the old twelvemonth ( Renault et al. 2007 ) . By April 2006, the Regional Health and Welfare Office reported 203 deceases that were straight ( due to low immune position ) or indirectly ( in associations with other implicit in conditions ) attributed with chikungunya infection, with a low mortality rate of 0.3/1000 people ( Renault et al. 2007 ) .

The Maldives encountered its first CHIKV eruption affecting 11879 confirmed and suspected instances on 121 of the 197 inhabited islands, observed by the surveillance system implemented by the Epidemiology Unit of the Department of Public Health ( DPH ) , from December 2006 to April 2007 ( Yoosuf et al. 2008 ) . The eruption commenced at the beginning of December 2006, peaked in hebdomad 6 and subsided to command degrees by hebdomad 11 before holding in April 2007. The epidemic was thought to be associated with post-tsunami building activities which provided genteelness sites for mosquitoes. Furthermore, about five to six aged patients died as consequence of co-morbidity and other conditions ( Yoosuf et al. 2008 ) .

Importing into Europe


In 2006, the United Kingdoms ‘ ( UK ) Health Protection Agency ‘s ( HPA ) Special Pathogens Reference Unit ( SPRU ) reported 133 imported instances of chikungunya ( Table 4 ) . The bulk of these tourers had travelled to the Indian Ocean islands ( 68 ) , between March and August 2006, where eruptions were go arounding, with Mauritius being the chief finish site affecting 58 imported instances, followed by 6 in the Seychelles, and 4 in Madagascar. However, when the eruptions were in diminution, merely one instance was detected in December ( HPA 2007 ) . Between August and December, 44 instances were imported from India and 10 instances were imported from Sri Lanka, between November and December ; states with reported recent chikungunya eruptions. Besides imported into the UK, where one instance from Nigeria, one from Tanzania, one instance from Kenya, and one instance from Australia. There had been no reference of chikungunya eruption in these states. However, the article did non province whether there had been reported sightings of Aedes mosquitoes in UK ( HPA 2007 ) .

The Piti & A ; eacute ; -Salp & A ; ecirc ; tri & A ; egrave ; re Hospital in Paris, France, reported 80 instances of Chikungunya infection imported by tourers who late visited the Southwest Indian Ocean part, between March 2005 and August 2006. The bulk of instances ( 52 ) were imported from La Reunion ( Hochedez et al. 2007 ) , a popular finish site for Gallic tourers ( HPA 2006 ) . Other finish sites reported were ; Mauritius with 18, Comoros with 4, Madagascar with 3, and Mayotte with 2 instances ( Hochedez et al. 2007 ) . Within the same period, Metropolitan France reported 766 imported instances, which correlated with the two moving ridges of the La Reunion eruption ( Figure 3 ) . At the extremum of the first La Reunion eruption, an norm of 20 instances was imported to France monthly. However, between August and November 2005, during the Southern Hemisphere winter, the instances decreased ( Krastinova et al. 2006 ) . A month after the extremum of the 2nd eruption, the figure of imported instances drastically increased. It can be argued that France is at hazard of future eruptions, in position that some of its dwellers are invariably sing the Southwest Indian Ocean parts ( Hochedez et al. 2007 ) , chiefly La Reunion and besides due to the inhabitancy of Aedes albopictus ( Krastinova et al. 2006 ) .

Chikungunya was seemingly imported into Italy by a male tourer coming from the Kerala state in India, who developed feverish illness two yearss into his vacation. The part he visited was Castiglonia di Cervia in June 2007. This was recorded by Ravenna state ‘s local wellness unit in the Emilia Romagna part, northeasterly Italy where 205 people developed CHIKV infection ( Rezza et al. 2007 ) . The vector, Aedes albopictus, was implicated in the spread of the virus which was so imported from Castiglione di Cervia into Castiglione de Revenna two small towns separated by a river. Mosquito control steps implemented in the country resulted in a decrease in chikungunya infection. However, the control step was non implemented in other small towns and therefore a new moving ridge occurred. The virus isolated from the eruption contained the same mutational alteration ( Ala226Val ) in the membrane merger E1 glycoprotein as the Indian Ocean discrepancy, thereby proposing that the Kerala strain could hold originated from the Indian Ocean eruption ( Rezza et al. 2007 ) .

Other European States

Tourism has been one of the chief methods of CHIKV distributions worldwide, including its importing into several European states. In 2006, the Bernhard-Nocht Institute for Tropical Medicine in Hamburg, Germany examined 720 samples from 680 European patients who became diagnostic upon return to Germany, Belgium, Switzerland, Denmark, and Poland from several finishs ( Table 2 ) ( Paning et al. 2008 ) . The bulk of patients had late visited states in the Indian Oceans ; Mauritius, the Seychelles, La Reunion and Madagascar, and other states ; Bali, Indonesia, Sri Lanka, India, Malaysia, Kenya and Thailand. Furthermore, most of these states have been implicated in recent CHIKV eruptions. No eruption were reported in these European states ; nevertheless, future eruptions can be hypothesised ( Paning et al. 2008 ) .

Concurrence with Dengue Fever and Malaria

In 2006 and 2007, Madagascar and Gabon reported co-infections between Chikungunya and DENV-1 or DENV-2 severally ( Ratsitorahina et al. 2008, Leroy et Al. 2009 ) . Contrary to CHIKV, dandy fever virus ( DENV ) is of Flavirivirus genus from Flaviridae household ; dwelling of four antigenically distinguishable but closely related serotypes ( DENV1-4 ) . It is transmitted by Aedes aegypti and Aedes albopictus, besides CHIKV transmittal vectors ( Cook and Zumla 2009 ) . DENV and CHIKV have similar clinical characteristics ( Yoosuf et al. 2008 ) . However, the lone difference is that CHIKV has arthalgia ( ) . The drawn-out incubation period of DENV ( 5-8 yearss ) differentiated it from CHIKV ( 2-7 yearss ) ; nevertheless, the difference is undistinguished ( Cook and Zumla 2009 ) . Therefore, serological diagnosing can be used to distinguish DENV to CHIKV ( Ratsitorahina et al. 2008 ) . Ratsitorahina et Al. ( 2008 ) and Leroy et Al. ( 2009 ) confirmed Aedes albopictus as the ruling transmittal vector of both CHIKV and DENV1 or 2. However, neither survey stated whether the vector could at the same time harbor both viruses. Furthermore, the survey by Vazeille et Al. ( 2008 ) demonstrated that Aedes aegypti has a higher susceptibleness to DENV-2 virus and a lower susceptibleness to CHIKV ; whereas Aedes albopictus is a more efficient vector for CHIKV than DENV-2 ( Vazeille et al. 2008 and Moutailler et Al. 2009 ) . Leroy et Al. ( 2009 ) farther demonstrated this theory in the Gabon eruption, as the bulk of the patients had CHIKV compared to DENV-2.

In May 1999 and February 2000, the Matete and Kingabwa quarters of Kinshasa in the Democratic Republic of Congo ( DRC ) reported two Chikungunya eruptions. CHIKV was the chief contributing factor in the first eruption ; nevertheless, during the 2nd eruption, grounds confirmed possibility of co-infections between CHIKV and Plasmodium falciparum ( Pastorino et al. 2004 ) . Malaria is a parasitic infection, of the Apicomlexa phylum, that chiefly infects host ‘s ruddy blood cells. It is transmitted by Anopheles species, whereas CHIKV is chiefly transmitted by Aedes species. Plasmodium falciparum is one of the four species of Human Malaria ( including Plasmodium vivax, Plasmodium malariae, and Plasmodium ovale ) . However, Plasmodium falciparum is the most terrible signifier of Malaria ( Cook and Zumla 2009 ) . Pastorino et Al. ( 2004 ) hypothesised that co-infections could be due to long term latency of Plasmodium falciparum, the presence of both transmittal vectors in the country or the pathogens sharing the same vectors. An experimental probe by Yadav et Al. ( 2003 as cited by Pastorino et Al. 2004 ) demonstrated that urban Anopheles stephensi ( Plasmodium falciparum vector ) could convey CHIKV.

Lack of Research

We are still in the preliminary phases of understanding the interaction between CHIKV and host unsusceptibility ( Kam et al. 2009 ) , despite increasing figure of reported eruptions, there are deficient groundss of up-to-date quality research ( Paning et al. 2008 ) . Therefore, eruptions should be utilised to implement entomological and epidemiological system in bettering our hapless cognition of the virus ( Pialoux et al. 2007 ) . Chretien and Linthicum ( 2007 ) argued that the Italian eruption should supply chances for developed states to beef up the public-health system of developing states in order to cut down the worldwide spread of eruptions. These can be done by implementing Entomological and Virological surveillance in Aedes albopictus infested countries ( Charell et al. 2008 ) . Renault et Al. ( 2007 ) utilised Deltamethrin insect powders to eliminate grownup mosquitoes, whereas Rezza et Al. ( 2007 ) utilised synergised pyrethrins. Furthermore, both writers utilised the biological larvicide, Bacillus thuringiensis israelensis, to destruct engendering sites ( Renault et al. 2007, Rezza et Al. 2007 ) ; nevertheless, Renault et Al. ( 2007 ) subsequently utilized Fenitrothion and temephos. Other control steps include educating the community on personal protection ( Ratsitorahina et al. 2008 ) . Although, no commercial vaccinum has been approved, several campaigners have been tested including the Formalin inactivated CHIKV vaccinum for the Indian strain, DRDE-06, ECSA genotype ( Tiwari et al. 2009 ) . Therefore, the writer believes that future eruptions can be avoided if more research on CHIKV is undertaken, and a worldwide surveillance system is implemented.


This reappraisal has demonstrated that touristry is one of the chief methods of CHIKV distributions worldwide, as it was the ground of several eruptions. CHIKV was transported throughout the Southwestern Indian Ocean islands by viraemic tourers sing different islands ( Figure 2 ) and Kerala, India, which was so imported into Italy ( Renault et al. 2007, Rezza et Al. 2007, Sissoko et Al. 2008, Yoosuf et Al. 2008 ) . However, eruptions require temperatures above 20oC and one-year rainfall over 500mm to keep Aedes mosquitoes ‘ populations ( Straetemans 2008, Tilson et Al. 2009 ) . Therefore, England is one of the least at hazard state, as Aedes albopictus is non present, and the temperature is unfavorable to keep mosquitoes ‘ life rhythm ( HPA 2007, Met Office 2010 ) . States such as France and Italy are at high hazard, due to the presence of Aedes albopictus and the debut of CHIKV ; although, Italy is the most at hazard due to a recent eruption ( Krastinova et al. 2006, Rezza et Al. 2007 ) . The high climatic alterations could ensue in lifting temperatures and increased rainfall that would favor the constitution of Aedes albopictus worldwide. All these emphasises the demand for Western medical specialty to be after for future CHIKV eruptions, by implementing a worldwide surveillance system in order to supervise eruptions and to execute vector control steps ( Charell et al. 2008 ) . Chikungunya have concurrency with Malaria and Dengue Fever ( Leroy et al. 2009, Ratsitorahina et Al. 2008 ) ; moreover, grounds suggests incorrect categorization of Chikungunya due to its resemblance to Dengue febrility. CHIKV is invariably mutating, therefore changeless development of a new vaccinum is required ( Tiwari et al. 2009 ) . Thereby, farther researches are needed.
