“…In the Maldives, the 20,000 existing wells represent the most important C. p. quinquefasciatus larval habitats (IYENGAR, 1952;VELIMIROVIC and CLARKE, 1975). In the Indian subcontinent, C. p. quinquefasciatus is present in rural areas where it develops in wells used for irrigation (YASUNO et al, 1975).…”

This paper is an attempt to synthesize information available on C. p. quinquefasciatus in Africa. The latter is presently found in most urban areas of the African continent and in rural settlements which show some trends towards urbanization. In East Africa, and the islands of the Indian Ocean, C. p. quinquefasciatus is one of the major natural vectors of Wuchereria bancrofti. In addition it can also transmit, under laboratory conditions, some other pathogenic agents.Preimaginal forms develop in different kinds of man-made breeding-places, especially those containing polluted water. The situation in each African region is reviewed in detail.Female behaviour during the different phases of the gonotrophic cycle is analysed, together with population dynamics.Control methods by synthetic insecticides are discussed in relation to resistance problems and the characteristics of the breeding sites. Other control methods based on the use of growth regulators, genetic manipulation, biological agents (parasites and predators) and environmental management have been investigated as well. Most of them cannot be easily applied or are not yet applicable for control operations.

“…We also observed that females with chikungunya exhibited more arthritogenic symptoms compared with the males in our previous work. 14 Overall,24.4% of children were reportedly affected during the 2019 outbreak in the Maldives, and in our cohort, we observed 20% with confirmed infection, compared with 17% of children reportedly affected in an outbreak on the Indian subcontinent. 25,39 These data indicate that the approximate proportion of children affected during outbreaks is generally less than one-fourth of all cases.…”

“…[15][16][17][18][19][20][21][22][23] The Maldives, a tropical island archipelago in the Indian Ocean, experienced a CHIKV outbreak in 2005-2006 involving anthropophilic vector Aedes species mosquitos that inhabit these small coral islands. 24 The last major outbreak of CHIKV was reported in 2006 and involved 11,879 cases. Infection was confirmed in 67 of these cases and resulted in six fatalities.…”

The chikungunya virus is an arthritogenic arbovirus that has re-emerged in many tropical and subtropical regions, causing explosive outbreaks. This re-emergence is due to a genomic polymorphism that has increased the vector susceptibility of the virus. The majority of those infected with chikungunya virus exhibit symptoms of fever, rash, and debilitating polyarthralgia or arthritis. Symptoms can persist for weeks, and patients can relapse months later. Fatalities are rare, but individuals of extreme age can develop severe infection. Here, we describe the 2019 outbreak, the second-largest since the virus re-emerged in the Maldives after the 2004 Indian Ocean epidemic, in which a total of 1,470 cases were reported to the Health Ministry. Sixty-seven patients presenting at the main referral tertiary care hospital in the Maldives capital with acute undifferentiated illness were recruited following a negative dengue serology. A novel point-of-care antigen kit was used to screen suspected cases, 50 of which were subsequently confirmed using real-time reverse transcription–polymerase chain reaction. We describe the genotype and polymorphism of Maldives chikungunya virus using phylogenetic analysis. All isolates were consistent with the East Central South African genotype of the Indian Ocean lineage, with a specific E1-K211E mutation. In addition, we explored the clinical and laboratory manifestations of acute chikungunya in children and adults, of which severe infection was found in some children, whereas arthritis primarily occurred in adults. Arthritides in adults occurred irrespective of underlying comorbidities and were associated with the degree of viremia.

A list is given of all the species of mosquitos so far recorded from the Seychelles, with their distribution in so far as this is known. A number of new records are included based on collections made recently by one of us (E.S.B.).One species and one subspecies new to science are here described for the first time. The first full descriptions of the male terminalia and pupae of certain other species are included.Some notes are given regarding the taxonomy, bionomics and local distribution of the species concerned and the zoogeography of the groups to which they belong.Appendices are devoted to corrections to the second edition of “The Mosquitoes of the Ethiopian Eegion”, Vol. I by G. H. E. Hopkins, and to the mosquitos of other islands in the western Indian Ocean.

Mosquitos of the Maldive Islands

Abstract: A large collection of mosquitos made in five atolls of the Maldive Islands has revealed the presence of 15 species. These are listed and notes of taxonomic interest on seven of them are given.
