Summary
Human Immunodeficiency Virus (HIV) subtype B remains dominant in Slovakia, primarily affecting men who have sex with men (MSM). While HIV-1 subtype B is prevalent, a slight increase in HIV diversity is observed.
Area of Science:
- Virology
- Epidemiology
- Public Health
Background:
- Slovakia has a low prevalence of Human Immunodeficiency Virus (HIV) infection.
- The primary transmission routes in Slovakia are among men who have sex with men (MSM) and heterosexual contact.
- Understanding circulating HIV subtypes is crucial for effective prevention and treatment strategies.
Purpose of the Study:
- To update the characterization of Human Immunodeficiency Virus (HIV) subtypes prevalent in Slovakia.
- To analyze the genetic diversity of HIV strains circulating in the Slovak population.
Main Methods:
- Prospective collection of HIV-1 partial pol gene sequences from 143 individuals between 2004 and 2008.
- Phylogenetic analysis of the collected HIV-1 partial pol gene sequences.
Main Results:
- HIV-1 subtype B was the most prevalent, accounting for 93.0% of cases, predominantly in the MSM group.
- Non-B subtypes were identified in 7.0% of individuals, including subtypes A, C, F, and various circulating recombinant forms (CRFs).
- Pure subtypes (4.9%) were more frequent than CRFs (2.1%), indicating a slight increase in HIV-1 subtype diversity.
Conclusions:
- HIV-1 subtype B continues to be the dominant strain in Slovakia.
- The observed increase in HIV-1 subtype diversity warrants continued surveillance and adaptation of public health interventions.

02:33Retroviruses
Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...
01:28Herpes
Herpes simplex type 1 (HSV‑1) is a widespread pathogen responsible for orolabial lesions. It is an enveloped, double-stranded DNA (dsDNA) virus belonging to the family Herpesviridae. Once the virus infects a host cell, its double‑stranded DNA genome is delivered into the nucleus, where a coordinated cascade of immediate‑early, early, and late gene expression directs viral DNA replication, structural protein synthesis, and virion assembly. After primary infection of epithelial cells, HSV-1...
01:23Genital Herpes
Genital herpes is a sexually transmitted infection primarily caused by herpes simplex virus type 2 (HSV-2), though herpes simplex virus type 1 (HSV-1) is increasingly implicated in genital infections, particularly among younger populations. Transmission occurs mainly through sexual contact, with asymptomatic viral shedding serving as a major route of spread. This characteristic makes HSV-2 difficult to control at a population level, as individuals may unknowingly transmit the virus even in the...
03:18Non-LTR Retrotransposons
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...
01:26Size and Structure of Viral Genomes
Viral genomes exhibit remarkable diversity in size, structure, and composition, influencing their replication strategies and interactions with host cells. These genomes consist of either DNA or RNA and may be linear or circular. Additionally, they can be single-stranded or double-stranded, with each configuration affecting how the virus propagates within a host. RNA viruses, for instance, generally have smaller genomes than DNA viruses, a factor that contributes to their high mutation rates and...
01:29Subviral Agents
Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...
