Stomach viruses can be spread through contaminated food or water and can cause viral gastroenteritis, meaning inflammation of the stomach and intestines (small and large). (nativeremedies.com)

CNS is protected by effective immune responses and multi-layer barriers, but some viruses enter with high-efficiency through the bloodstream and some by directly infecting the nerves that innervate the tissues. (wikipedia.org)

Rabbit haemorrhagic disease virus Lagovirus europaeus /GI.1d variant (GI.1d/RHDV) was identified in 1990 in France, and until the emergence of the new genotype GI.2, it was the main variant circulating in the country. (biomedcentral.com)

Chronic obstructive pulmonary disease patients with type 2 inflammation saw rapid and sustained improvements in their disease after treatment with the monoclonal antibody dupilumab, according to a yearlong, Phase 3 clinical trial reported in the New England Journal of Medicine. (news-medical.net)

Both are required for pathogenicity of vaccinia virus in mice infected by intracranial injection. (rcsb.org)

Viruses are ultramicroscopic particles. (brainkart.com)
Four tested doses, negligible (10 − 1 viral genome copies), low (10 4 ), high (10 7 ) and very high (10 11 ) were quantified using a method combining density gradient centrifugation of the viral particles and an RT-qPCR technique developed to quantify genomic RNA (gRNA). (biomedcentral.com)
Determining the minimum dose of viral particles required to cause mortality in rabbits is an important input for in vivo studies. (biomedcentral.com)
It will then multiply and produce more virus particles. (nativeremedies.com)

When we help people with HIV improve their overall health and CD4 count recovery, we can also improve their prognosis if they do contract the virus," explained Hazra. (healthline.com)

Once the sanitary restrictions are lifted, circulation of seasonal respiratory viruses is expected to resume and will offer the opportunity to study their interactions, notably with severe acute respiratory syndrome coronavirus 2. (cdc.gov)
Some of these viruses cause relatively mild illnesses, while others can cause severe, life-threatening disease. (who.int)
Among them were severe acute respiratory syndrome (SARS), bird flu, swine flu, Middle East respiratory syndrome (MERS), ebola virus disease. (banglajol.info)
The severe version of the disease, that requires hospitalization, is unusual and it is shows low lethality. (bvsalud.org)

Treatments of proven efficacy are currently limited mostly to herpes viruses and human immunodeficiency virus. (wikipedia.org)

This Special Issue of the Viruses journal is dedicated to the diagnostic and therapeutic advancements of viral liver diseases with the aim of giving a complete update not only on the treatments currently available and future developments, but also on the still unmet needs in the management of special patient populations.
