The percentage of positive hMPV tests (averaged over three weeks) peaked in the U.S. during mid-March at about 19% for antigen tests and 11% for PCR tests, data show.
Data from the National Respiratory and Enteric Virus Surveillance System (NREVSS) shows that among lab tests submitted for HMPV, more than 2% tested positive through the first week of January ...
"HMPV stands for human metapneumovirus, which is a respiratory virus typically seen in the winter season," Dr. Zachary Hoy, MD, infectious disease specialist at Pediatrix, told Parade. "It can ...
Human metapneumovirus (HMPV or hMPV) is a negative-sense single-stranded RNA virus of the family Pneumoviridae and is closely related to the avian metapneumovirus (AMPV) subgroup C. It was isolated for the first time in 2001 in the Netherlands by using the RAP-PCR (RNA arbitrarily primed PCR ) technique for the identification of unknown viruses ...
Human infectious diseases may be characterized by their case fatality rate (CFR), the proportion of people diagnosed with a disease who die from it (cf. mortality rate).It should not be confused with the infection fatality rate (IFR), the estimated proportion of people infected by a disease-causing agent, including asymptomatic and undiagnosed infections, who die from the disease.
In immunosuppressed people, parainfluenza virus infections can cause severe pneumonia, which can be fatal. [ 19 ] HPIV-1 and HPIV-2 have been demonstrated to be the principal causative agent behind croup ( laryngotracheobronchitis ), which is a viral disease of the upper airway and is mainly problematic in children aged 6–48 months of age.
Public health experts are warning of a ‘quad-demic’ this winter. Here’s where flu, COVID, RSV, and norovirus are spreading
The virus can be spread after only a few days after the infection which suggests that this virus has no latency period. [4] Because of the human MPV, found in 2001, it is not defined as zoonotic. [2] Even though there is a great homology between hMPV and aMPV-C, no infections of the aMPV-C in humans have been noticed. [6]
