It is estimated to affect %5-%15 of the global population and causing about 250000 to 500000 yearly deaths, rising to millions in some pandemic years. The aim of this study was an epidemiological survey of influenza A v...

[ 6 ] - آبله و آمادگی برخورد با حملات بیوتروریستی

Smallpox is a serious infectious disease to have ever afflicted mankind. Smallpox is caused by variola virus, which belongs to a family of viruses known as poxviridae. Pox viruses are large DNA viruses which are 200-400 nm. The smallpox prodrome is characterized by the sudden on-set of high fever (38.5°C-40.5°C) and malaise 10 to 14 days after exposure. As populations grew and migrated, the dis...

[ 7 ] - پاپیلوما ویروس و سرطان

Papillomaviruses are small tumor viruses with a genome of approximately 8000 base pairs. They are found in many different types and infect a wide range of animals (from birds to rabbits, dogs, sheep and cattle) and several primates including humans. So far, over 100 different types of human papillomavirus (HPV) have been identified, among which one-third infect epithelial cells in the genital t...

[ 8 ] - The Prevalence of HBV and HCV Infection in HIV Positive Patients in Norht of Iran

Background: HIV infected persons are also at risk for Infection with other pathogens, like Hepatitis B virus (HBV) and Hepatitis C virus (HCV). One of the main steps in the planning of treatment and prevention is the study of the HIV positive population who have HBV and/or HCV infection. The objective of this study was to determine the prevalence of HIV and Hepatitis B and C dual infection in ...

[ 9 ] - Prevalence of Influenza A/H1N1 Virus in North of Iran, 2013 to 2017
