The case received wide international coverage that prompted many to comment on it, including neurologist, well-known skeptic and science-based medicine advocate Steven Novella, who called Lanka "a crank".As outbreaks easily occur in under-vaccinated populations, the disease is seen as a test of sufficient vaccination within a population. Measles outbreaks have been on the rise in the United States, especially in communities with lower rates of vaccination. A different vaccine distribution within a single territory by age or social class may define different general perceptions of vaccination efficacy. It is often introduced to a region by travelers from other countries and it typically spreads to those who have not received the measles vaccination. Alternative names
Other names include morbilli, rubeola, red measles, and English measles. Research
In May 2015, the journal Science published a report in which researchers found that the measles infection can leave a population at increased risk for mortality from other diseases for two to three years. Results from additional studies that show the measles virus can kill cells that make antibodies were published in November 2019.A specific drug treatment for measles, ERDRP-0519, has shown promising results in animal studies, but has not yet been tested in humans.

Several types of volcanic eruptions—during which lava, tephra (ash, lapilli, volcanic bombs and volcanic blocks), and assorted gases are expelled from a volcanic vent or fissure—have been distinguished by volcanologists. These are often named after famous volcanoes where that type of behavior has been observed. Some volcanoes may exhibit only one characteristic type of eruption during a period of activity, while others may display an entire sequence of types all in one eruptive series. There are three different types of eruptions: 

Magmatic eruptions are the most well-observed type of eruption. They involve the decompression of gas within magma that propels it forward. Phreatic eruptions are driven by the superheating of steam due to the close proximity of magma. This type exhibits no magmatic release, instead causing the granulation of existing rock. Phreatomagmatic eruptions are driven by the direct interaction of magma and water, as opposed to phreatic eruptions, where no fresh magma reaches the surface.Within these wide-defining eruptive types are several subtypes. The weakest are Hawaiian and submarine, then Strombolian, followed by Vulcanian and Surtseyan. The stronger eruptive types are Pelean eruptions, followed by Plinian eruptions; the strongest eruptions are called Ultra-Plinian. Subglacial and phreatic eruptions are defined by their eruptive mechanism, and vary in strength.
