Principles of Disease Surveillance

669
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...

Viral Recombination00:57

Viral Recombination

25.4K
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

40.1K
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...

Leaky Scanning02:28

Leaky Scanning

5.8K
During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA.  Marilyn Kozak discovered that the sequence RCCAUGG (where R...

Area of Science:

  • Pediatrics
  • Immunology
  • Public Health

Background:

  • Influenza poses a significant annual health risk to children, causing considerable illness and death.
  • Approved inactivated and live influenza vaccines offer protection but exhibit variable effectiveness.
  • Challenges in vaccination programs exist, particularly in tropical and subtropical regions.

Purpose of the Study:

  • To summarize the current understanding of influenza in children.
  • To highlight the role and limitations of current influenza vaccines.
  • To discuss challenges and adjuncts in pediatric influenza control.

Main Methods:

  • Review of existing literature on pediatric influenza.
  • Analysis of influenza vaccine efficacy and performance data.
  • Examination of global vaccination program logistics.

Main Results:

  • Influenza vaccines are generally safe and effective in children, though yearly effectiveness varies.
  • Recent reduced performance of live-attenuated influenza vaccines requires further investigation.
  • Logistical and feasibility issues impede vaccination programs in tropical/subtropical areas.

Conclusions:

  • Influenza vaccines remain critical for pediatric protection, necessitating ongoing research into effectiveness.
  • Antiviral medications serve as a vital supplement to vaccination strategies for prevention and treatment.
  • Addressing global disparities in vaccination programs is essential for comprehensive influenza control.
