Insights

Italy faced a significant measles outbreak in 2017-2018, with genotypes B3 and D8 identified. Monitoring virus strains helps public health officials track transmission routes and alert the public and travelers.

Area of Science:

  • Epidemiology
  • Virology
  • Public Health

Background:

  • Italy reported a major measles outbreak in 2017 with over 5,400 cases.
  • The outbreak continued into 2018, with over 2,000 notified cases in the first six months.

Purpose of the Study:

  • To identify the specific measles virus genotypes responsible for the 2017-2018 Italian outbreak.
  • To understand potential transmission routes for public health interventions.

Main Methods:

  • Analysis of notified and confirmed measles cases in Italy.
  • Laboratory confirmation and genotyping of measles virus strains.

Main Results:

  • Genotypes B3 and D8 were identified as the primary strains circulating during the outbreak.
  • A substantial number of measles cases were confirmed through laboratory testing.

Conclusions:

  • Genotype surveillance is crucial for understanding measles transmission dynamics.
  • Monitoring circulating strains aids national health authorities in issuing timely warnings to the public and travelers.

Viral Recombination00:57

Viral Recombination

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.

Crossing Over01:34

Crossing Over

Unlike mitosis, meiosis aims for genetic diversity in its creation of haploid gametes. Dividing germ cells first begin this process in prophase I, where each chromosome—replicated in S phase—is now composed of two sister chromatids (identical copies) joined centrally.
The homologous pairs of sister chromosomes—one from the maternal and one from the paternal genome—then begin to align alongside each other lengthwise, matching corresponding DNA positions in a process...

Crossing Over01:30

Crossing Over

Crossing over is the exchange of genetic information between homologous chromosomes during prophase I of meiosis I. Genetic recombination gives rise to allelic diversity in the newly formed daughter cells. In humans, crossing over produces genetically distinct haploid egg and sperm cells that undergo fertilization to produce unique offspring. Before cell division starts, the germ cell’s chromosome(s) undergo duplication in the S phase of the cell cycle. As the cells enter prophase I,...

Cross-Sectional Research

In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...
