After a lytic cycle, virus enters a dormant phase; generally not detectable, no symptoms; can reactivate and result in recurrent infections.The Clinical Virology Laboratory is a full service virology laboratory that performs molecular methods, rapid antigen testing, culture and serology.
Virology is a rapidly changing field and the laboratory is continually modifying its test menu and test algorithms in order to keep abreast of current developments and provide the best services to our patients. The Laboratory Director and Laboratory Manager are available by phone or email for consultations and questions.

A medical technologist prepares patient samples for analysis by polymerase chain reaction PCRa test that amplifies viral genetic material and allows detection of very small amounts, very quickly.
The Virology Laboratory detects over 20 different virus. Flasks like these are used to prepare buffer solutions for use in virus detection methods. Stirring with a magnetic stir bar helps dissolve the various components.
Some viruses do not grow in cell culture, or grow slowly. In such cases, other viral detection methods must be used.

A modern clinical virology laboratory performs various tests, such as rapid antigen testing, serology or molecular diagnostics in order to provide the best services to the healthcare institutions and patients. Effective use of these diagnostic platforms enables the timely detection and control of infectious diseases caused by viral agents. We offer a rich portfolio of parameters and technologies for clinical virology, with a particular focus on viruses causing gastrointestinal infections and respiratory infections.
The influenza, also called flu, is the most common respiratory infectious disease whereby influenza types A and B cause the annually occurring influenza epidemics. Worldwide, 3 — 5 million people are infected with influenza and approximately—die from this disease each year. Noroviruses are a major cause of gastroenteritis world-wide with an estimated 23 million cases a year in the USA.
They are frequently the reason of outbreaks in communal facilities, for instance nursing homes, hospitals, prisons, and cruise ships. Since norovirus outbreaks are reported more often than outbreaks caused by bacterial pathogens, they may have a considerable impact on public health.
The reliable norovirus diagnostic tests from R-Biopharm help clinical laboratories of all sizes detect the infection with norovirus in a simple and fast manner.
Our virology catalogue offers technologies that meet the diagnostic and organizational needs of small to large laboratories, including:. Influenza — the most common respiratory infectious diseases worldwide The influenza, also called flu, is the most common respiratory infectious disease whereby influenza types A and B cause the annually occurring influenza epidemics.
Norovirus diagnostics: fast diagnostics in outbreaks — always on the forefront Noroviruses are a major cause of gastroenteritis world-wide with an estimated 23 million cases a year in the USA.
Innovative diagnostic solutions for virology Our virology catalogue offers technologies that meet the diagnostic and organizational needs of small to large laboratories, including:. Real-time PCR test kits suitable for different open-platform cyclers Enzyme immunoassays validated for automation platforms Rapid tests in the form of a cassette or a dipstick — a straightforward, fast, sensitive method for detection of viral antigens in small sets of samples.

Even what we do know — that elderly people are more at risk, that this is a new virus but resembles other known epidemics, that it is highly infectious — requires more explanation.
This interview, conducted by Maria Epifanova, was originally published by Novaya Gazeta. This English translation has been updated and authorized for sharing with the World Economic Forum. I would like to start with a general question: there are a lot of discussions and speculations about COVID, but could you summarize the facts that we know about the virus for sure? It is certainly a new virus for the human population.
It resembles very much the SARS virus which emerged in It also relates, but less closely, to another virus which emerged a few years later — the MERS virus. It was even more deadly, it killed one in three people who got infected. But both of these epidemics disappeared following much less drastic measures than the ones implemented today. The present virus, COVID, is clearly more infectious and is mainly transmitted via aerosols from people who cough or sneeze etcbut you can also get it by contact with objects that infected people, who are not necessarily sick, have touched.
It has spread all over the world and is present in almost all countries where they are able to test for it. This is also different from the previous epidemics because it took a long time to test for those — now we already have tests. This family of coronaviruses has been with humans and animals for a long time and causes mild infections like the common cold, but this new virus is much more aggressive than all other members of the family. There may also be many infected people who do not get sick and that we do not test.
It is a completely different virus from the Influenza viruses which belong to a very different group, meaning that flu vaccine or flu medication will not help. For now, we have no medication or vaccine for the virus.

The genetic structure of this virus and a flu virus are as different as we are from dinosaurs. Many people still compare this virus to SARS and believe the measures taken by governments are excessive. Why should we not compare it with SARS?
