Background:In the recent decade, the reverse genetics method has been broadly used for rescue of negative-stranded RNA viruses from cDNA or viral minigenomes. This technique has been applied to study different steps in virus replication and virus-host interactions. Reverse genetics could also be implemented for design of new vaccines. The T7 RNA polymerase activity as well as virus (nucleocapsi...
Abstract Background and Aims: Medical students are exposed to various infectious diseases during their clinical training period, including measles and rubella. In Iran, to control the outbreaks of measles and rubella a mass vaccination campaign was conducted on 2003. The present investigation evaluates Immunity to measles and rubella in a group of Babol medical students and determines the ...
Background Measles is a contagious illness with symptoms including fever, cough and rash. Although after the start of vaccination, its mortality rate has decreased significantly, but in some countries, the disease still leads to dangerous complications. Since infectious diseases such as measles has long been of interest to practitioners, in this study the perspective of Traditional Iranian Medi...
Infectious diseases spreading in a human population occasionally exhibit sudden transitions in their qualitative dynamics. Previous work has successfully predicted such transitions in New York City's historical measles incidence using the seasonally forced susceptible-infectious-recovered (SIR) model. This work relied on a dataset spanning 45 years (1928-1973), which we have extended to 93 year...
In 2000, the circulation of indigenous measles was interrupted in Catalonia as a result of the activities of the elimination programme introduced in 1991. However, various transmission chains occurred in the indigenous population after the introduction of an imported case, and this caused a total change in the existing situation of elimination. The objective of this study was to analyze the epi...
As part of measles elimination effort, evaluation of the vaccination program and real-time assessment of the epidemic dynamics constitute two important tasks to improve and strengthen the control. The present study aimed to develop an epidemiological modeling method which can be applied to estimating the vaccine efficacy at an individual level while conducting the timely investigation of the ep...
BACKGROUND Sri Lanka was the first country in the Southeast Asian region to achieve its measles elimination goal in 2011. In 2012, the measles immunization schedule changed from a measles vaccine at 9 months to a measles, mumps and rubella vaccine at 12 months. However in 2013, Sri Lanka reported its worst recent outbreak of measles. This study investigated a part of this outbreak in order to d...
