概括
由于出生率下降,家庭规模的下降显著影响了麻疹等传染病的动态. 较低的出生率比家庭混合变化在疾病传播中的作用更大.
科学领域:
- 流行病学 流行病学
- 数学建模的数学建模
- 人口统计学 人口统计学
背景情况:
- 家庭传播是传染病的关键.
- 以前的模型没有考虑影响家庭规模的人口变化.
研究的目的:
- 为了建模长期麻疹传播动态,考虑到家庭规模的人口变化.
- 分析家庭和年龄结构混合对不同家庭大小分布的疾病动态的影响.
主要方法:
- 利用一种包含人口变化和家庭规模的疾病传播模型.
- 包括家庭和年龄结构混合.
- 模拟的流行性麻疹传播使用汇总的全球人口统计数据.
主要成果:

Conservation of Small Populations
13.1K
Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

Steps in Outbreak Investigation
114
In the ever-evolving field of public health, statistical analysis serves as a cornerstone for understanding and managing disease outbreaks. By leveraging various statistical tools, health professionals can predict potential outbreaks, analyze ongoing situations, and devise effective responses to mitigate impact. For that to happen, there are a few possible stages of the analysis:

Infection
7.8K
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Mismatch Repair
4.8K
Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.
