The new China virus - Human Metapneumovirus, its infectivity and rapid spreadis it a threat?

Abstract

Human Metapneumovirus (HMPV) causes a highly
infectious respiratory disease for all ages and is part of the
Pneumoviridae family, but causes diseases for respiratory,
milder to most severe; from pneumonia, to bronchiolitis,
up to COPD. The virus is pleomorphic in shape and size,
varying between 150 nm to 600 nm but very contagious
and easily spread by droplets via coughing or sneezing.
Children are more at risk giving it a name of kid’s virus.
People with a weak immune system as those with heart or
lung diseases are also easy victims. The symptoms of
HMPV include runny nose, nasal congestion, cough, and
fever. HMPV is also known to cause pneumonia. The
incubation period is estimated to be 3-6 days with most
cases lasting two to five days and then resolving on their
own. At times, more severe respiratory symptoms appear
as pneumonia requiring hospitalization. The treatment is
symptomatic and includes antihistamines, fever reducers,
and broncodilators.
