Summary
Hantavirus pulmonary syndrome (HPS) is not reported in Mexico, despite similar conditions to other countries. This review found seven hantavirus genotypes in Mexican rodents, three zoonotic, indicating a potential public health risk.
Area of Science:
- * Veterinary Medicine
- * Infectious Diseases
- * Epidemiology
Background:
- * Hantaviruses transmitted by rodents cause hantavirus pulmonary syndrome (HPS) in the Americas.
- * No HPS cases have been reported in Mexico, despite environmental similarities to regions with known cases.
Purpose of the Study:
- * To assess the hantavirus situation and public health risk in Mexico.
- * To identify hantavirus genotypes and seroprevalence in Mexican rodents.
- * To determine potential circulating hantaviruses based on host distribution and phylogenetic diversity.
Main Methods:
- * Systematic review of studies on hantaviruses in rodents from 1999 to 2017.
- * Analysis of rodent species, seroprevalence, and hantavirus genotypes.
- * Phylogenetic diversity assessment of hantaviruses in hosts distributed in Mexico.
Main Results:
- * 3,862 rodents across 82 species were tested; 392 individuals (43 species) were seropositive.
- * Seroprevalence ranged from 0 to 69.22%.
- * Seven hantavirus genotypes identified in Mexico, with three being zoonotic; 16 genotypes may circulate, posing potential public health risks.
Conclusions:
- * Several hantavirus genotypes, including zoonotic ones, are present in Mexican rodents.
- * Widespread rodent species harbor high viral diversity, suggesting a potential public health risk.
- * Multidisciplinary surveillance of rodents is recommended for public health protection.

01:27Psychodynamic Perspectives on Personality
1.5K
The psychodynamic perspective in psychology asserts that most personality functions operate unconsciously, outside of awareness. This means that the motives and emotions driving behavior often remain hidden, automatically buried in the unconscious mind as a defense mechanism to shield us from psychological distress. According to this theory, the unconscious mind contains thoughts, memories, and emotions that are too disturbing to face directly.

01:19The Behavioral Perspective on Personality
804
Behaviorists view personality as primarily shaped by environmental reinforcements and consequences. According to this perspective, behavior is influenced by external stimuli, and individuals adjust their actions based on rewards and punishments. Over time, learning histories — accumulated patterns of reinforcement — play a significant role in shaping personality. Behaviors that lead to positive outcomes are reinforced, while those resulting in negative outcomes are diminished.

01:23Criticisms of the Evolutionary Perspective

In a study where individuals posing as strangers offered compliments and proposed casual sex to students, the responses differed significantly based on gender. Not a single woman accepted the proposal, while 70% of the men agreed. This outcome provides a useful scenario to explore through the lens of evolutionary psychology and social learning theory, highlighting the diverse perspectives on human sexual behaviors.

01:30Social Cognitive Perspective on Personality
994
Social cognitive perspectives on personality emphasize the importance of conscious awareness, beliefs, expectations, and goals in shaping behavior. These perspectives incorporate behaviorist principles, such as learning through reinforcement and conditioning, but extend beyond them by highlighting human reasoning and planning. Unlike traditional behaviorist views, social cognitive theory focuses on how individuals reflect on their past experiences and plan for future outcomes by considering...

01:14Changes in Skin Color: Clinical Perspectives
3.3K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

01:10Electrical Current
6.8K
Electrical current is defined as the rate at which charge flows. When there is a large current present, such as that used to run a refrigerator, a large amount of charge moves through the wire in a small amount of time. If the current is small, such as that used to operate a handheld calculator, a small amount of charge moves through the circuit over a long period of time. The SI unit for current is the ampere (A), named for the French physicist André-Marie Ampère (1775–1836).
