Modeling the HIV epidemic in MSM in Cyprus: reaching only the 95-95-95 cascade of care targets fails to reduce HIV incidence by 90% in 2030.

National responses should be improved and accelerated to meet the target of ending the Acquired ImmunoDeficiency Syndrome (AIDS) epidemic by 2030. In the Republic of Cyprus, Men who have Sex with Men (MSM) are disproportionately affected by Human Immunodeficiency Virus (HIV), accounting approximately for half of all annual HIV diagnoses. This study assesses the evolution of HIV incidence in MSM in Cyprus until 2030 using a model calibrated to Cypriot epidemiological data.

HIV-1 transmission networks across Cyprus (2010-2012).

A molecular epidemiology study of HIV-1 infection was conducted in one hundred diagnosed and untreated HIV-1-infected patients in Cyprus between 2010 and 2012, representing 65.4% of all the reported HIV-1 infections in Cyprus in this three-year period, using a previously defined enrolment strategy. Eighty-two patients were newly diagnosed (genotypic drug resistance testing within six months from diagnosis), and eighteen patients were HIV-1 diagnosed for a longer period or the diagnosis date was unknown.

HIV-1 Infection in Cyprus, the Eastern Mediterranean European Frontier: A Densely Sampled Transmission Dynamics Analysis from 1986 to 2012.

Since HIV-1 treatment is increasingly considered an effective preventionstrategy, it is important to study local HIV-1 epidemics to formulate tailored preventionpolicies. The prevalence of HIV-1 in Cyprus was historically low until 2005. To investigatethe shift in epidemiological trends, we studied the transmission dynamics of HIV-1 in Cyprususing a densely sampled Cypriot HIV-1 transmission cohort that included 85 percent ofHIV-1-infected individuals linked to clinical care between 1986 and 2012 based on detailedclinical, epidemiological, behavioral and HIV-1 genetic information.

Molecular characterization of HIV type 1 strains from newly diagnosed patients in Cyprus (2007-2009) recovers multiple clades including unique recombinant strains and lack of transmitted drug resistance.

HIV-1 evolution generates substantial genetic diversity among isolates, the majority of which are represented in areas where multiple strains cocirculate. A heterogeneous genetic HIV-1 pool has been found in Cyprus, directing us to determine the dynamics of the local HIV-1 infection by characterizing strains isolated from 74 subjects during 2007-2009, representing 88% of the known-living HIV-1-infected population, of whom 53 are newly diagnosed therapy-naive patients and 21 are chronic patients, according to the European HIV Resistance guidelines. Near full-length genome sequences were amplified by RT-nested PCR using diluted RNA from all HIV-1 seropositives and sequenced using a newly designed assay.

Genetic analysis of HIV type 1 strains from newly infected untreated patients in cyprus: high genetic diversity and low prevalence of drug resistance.

Abstract The molecular epidemiology of HIV-1 infection was first studied in Cyprus in the mid-1990s, but the extent of HIV-1 diversity and the prevalence of drug resistance have remained elusive. In an effort to address this issue, the present study examined HIV-1 strains isolated from 37 newly diagnosed untreated HIV-1 patients, representing 72% of the total number of newly diagnosed and drug-naive patients in the period 2003 to 2006. DNA sequences encoding the gag (p17, p24, p2, p7, p1, and p6), pol (protease and reverse transcriptase), and env (gp160) regions were amplified by RT-PCR from plasma HIV-1 RNA from all patients and sequenced using a newly designed methodology.
