RSV is transmitted from an infected child by secretions from the nose or mouth by direct contact or by droplets in the air. The period of greatest contagiousness is in the first 2 to 4 days of the infection. RSV can last between 2 to 8 days, but symptoms can remain up to 3 weeks. RSV occurs more commonly during the winter and early spring. Respiratory syncytial virus (RSV) infects almost all children at least once before they are 2 years old.
Definition of Cadence. Cadence is derived from a Latin word â cadentia â that means âa fallingâ. It is the term used to signal the rising and falling of the voice when reading a literary piece. In poetry, it is the momentary changes in rhythm and pitch. Cadences help set the rhythmic paces of a literary piece.
In music of the common practice period, cadences are divided into four types according to their harmonic progression: authentic, plagal, half, and deceptive. Typically, phrases end on authentic or half cadences, and the terms plagal and deceptive refer to motion that avoids or follows a phrase-ending cadence. harmonic cadence is a progression of (at least) two chords that concludes a phrase, section, or piece of music. A rhythmic cadence is a characteristic rhythmic pattern that indicates the end of a phrase.
