Summary
The Swiss HIV Cohort Study Viral NGS Database (SHCND) manages next-generation sequencing (NGS) data for HIV research. This database supports studies on HIV pathogenesis, treatment, and molecular epidemiology in Switzerland.
Area of Science:
- Virology
- Genomics
- Bioinformatics
Background:
- Viral genome sequencing is crucial for understanding HIV, including resistance mutations and transmission dynamics.
- Next-generation sequencing (NGS) has become the preferred method for HIV genome sequencing, offering comprehensive within-host diversity analysis.
Purpose of the Study:
- To establish a centralized database for managing and analyzing large volumes of HIV next-generation sequencing (NGS) data.
- To address challenges in data management, storage, analysis, and reproducibility for HIV NGS data.
Main Methods:
- Development and implementation of the Swiss HIV Cohort Study Viral NGS Database (SHCND).
- Integration of data from the Swiss HIV Cohort Study (SHCS) and Zurich Primary HIV Infection Cohort Study (ZPHI).
- Accumulation of NGS sequences from 5,178 unique people with HIV (PWH) since 2018.
Main Results:
- The SHCND successfully manages high loads of raw and processed NGS data, storage, and computational resources.
- The database supports sophisticated bioinformatic analyses and ensures reproducibility.
- SHCND has accumulated sequences from 5,178 unique PWH, contributing to numerous research projects.
Conclusions:
- The SHCND is a vital resource for HIV genomics research in Switzerland.
- The database facilitates research on HIV pathogenesis, treatment, drug resistance, and molecular epidemiology.
- SHCND enhances the capacity for advanced HIV research using NGS data.

Next-generation Sequencing
The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.
Next-Generation Sequencing Methods
Although all next-generation methods use different technologies, they all share a set of standard features.

Size 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...
Human Virome
The human body harbors a vast and diverse viral community known as the human virome. The virome includes bacteriophages that infect bacteria, and eukaryotic viruses that infect human cells. Transient dietary and environmental viruses also contribute to this dynamic ecosystem. Estimates suggest the human body may contain on the order of 10¹³ viral particles, though abundance varies widely by body site and detection method.Comprehensive characterization of the virome has become possible only with...
