Steps in Outbreak Investigation01:18

Steps in Outbreak Investigation

428
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:

Principles of Disease Surveillance01:26

Principles of Disease Surveillance

408
Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...

Single Nucleotide Polymorphisms-SNPs01:05

Single Nucleotide Polymorphisms-SNPs

17.7K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Viral Recombination00:57

Viral Recombination

24.8K
Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

Viral Mutations00:36

Viral Mutations

39.4K
A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...

Rous Sarcoma Virus (RSV) and Cancer

6.0K
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

Area of Science:

  • * Epidemiology and Virology
  • * Infectious Diseases
  • * Public Health

Background:

  • * The 2002/2003 SARS pandemic was the first major global health crisis of the 21st century.
  • * Severe Acute Respiratory Syndrome (SARS) originated in China and rapidly spread worldwide, causing significant mortality.
  • * The disease presented as severe pneumonia with potential for respiratory and enteric complications.

Purpose of the Study:

  • * To analyze the emergence and spread of SARS-CoV.
  • * To understand the zoonotic origins and human transmission of the virus.
  • * To characterize SARS as a model for emerging infectious diseases.

Main Methods:

  • * Retrospective analysis of epidemiological data from the 2002/2003 outbreak.
  • * Review of virological studies on SARS-CoV.
  • * Examination of viral genetic mutations and transmission pathways.

Main Results:

  • * The SARS epidemic resulted in over 8,000 cases and 774 deaths globally.
  • * SARS-CoV, a novel coronavirus, was identified as the causative agent.
  • * Transmission occurred from bats to intermediate hosts (small carnivores) and then to humans, with subsequent human-to-human spread.

Conclusions:

  • * SARS-CoV's ability to infect humans and transmit between them was facilitated by viral receptor gene mutations.
  • * The SARS pandemic serves as a critical case study for understanding emerging infectious diseases.
  • * Zoonotic spillover and viral adaptation are crucial factors in the emergence of novel pathogens.
