The greater the number of individuals who are partially protected, the smaller the pool of
susceptible individuals who are at risk of infection.
In this paper, we provide a different approach to the contagious effect of criminal behavior in
susceptible individuals. Rather than considering direct contagious effect by the social environment, we consider a contagious effect by criminals already convicted and who control criminal activities from inside prison, a common effect of some countries like Brazil.
where I(t) indicates the number of infective individuals at time t in an infinite population of
susceptible individuals. Gielen [14] explicitly derived the probability distribution of the number of infective individuals at any time t, using which he arrives at several interesting results.
Here, the first approach to improving the estimator of the initial number of
susceptible individuals was to employ the likelihood function of [5].
It is more reasonable to consider the impulsive vaccination strategy for the
susceptible individuals; there are fewer literatures that researched HBV infection with impulsive vaccination already [25, 26].
The human health impacts of poor air quality can lead to asthma and respiratory issues especially in highly
susceptible individuals such as children, the elderly or those in minority and/or disadvantaged populations.
five-dose DTaP schedule conducted in the setting of a mature vaccination program and allowing for a comparison of fully vaccinated and unvaccinated children." Together with the findings of previous studies that used different methods to examine this issue, the results "suggest that waning of immunity following DTaP vaccination may have resulted in a much larger pool of
susceptible individuals" than previously realized.
While the cause of lupus is poorly understood, some work suggests that the Epstein-Barr virus may trigger the disease in
susceptible individuals.
New research suggests extreme physical activity can scar the right ventricle of the heart in
susceptible individuals.
New research suggests extreme physical activity can scar the right ventricle of the heart in
susceptible individuals. Athletes taking part in high-endurance activities such as marathons, triathlons, or alpine cycling could be at risk without knowing it.
