population

The nis-py-api is a Python package that streamlines access to the National Immunization Survey (NIS) data from the CDC. The package helps with downloading, cleaning, and caching data. It allows access to standardized validated data on flu, COVID, RSV and Nirsevimab data, at multiple geographical resolution, and by age group.

viral Infectious disease

Viruses Infection

An acute viral infection of the respiratory tract, occurring in isolated cases, in epidemics, or in pandemics; it is caused by serologically different strains of viruses (influenzaviruses) designated A, B, and C, has a 3-day incubation period, and usually lasts for 3 to 10 days. It is marked by inflammation of the nasal mucosa, pharynx, and conjunctiva; headache; myalgia; often fever, chills, and prostration; and occasionally involvement of the myocardium or central nervous system.

influenza

Influenza

A respiratory tract infection caused by a virus. Viruses represent the most common causes of upper and lower respiratory tract infections and include rhinoviruses, influenza viruses, parainfluenza viruses, and respiratory syncytial virus.

viral respiratory tract infection

Viral Respiratory Tract Infection

A census that is the specific outcome of a population demographic survey.

population demographic census

Population Demographic

Infection with the respiratory syncytial virus, an RNA virus of the genus Pneumovirus, in the family Paramyxoviridae, which is characterized by the formation of syncytia in tissue culture. It causes minor respiratory infection with rhinitis and cough in adults, but is capable of causing severe bronchitis and bronchopneumonia in young children.

respiratory syncytial virus infectious disease

Respiratory Syncytial Virus Infection

Minute infectious agents whose genomes are composed of DNA or RNA, but not both. They are characterized by a lack of independent metabolism and the inability to replicate outside living host cells.

Viruses

Unidentified influenza virus is a species of ssRNA(-) virus in the family Orthomyxoviridae.

unidentified influenza virus

Influenza virus

a census of infectious disease control strategies put into place to reduce infection acquisitions that are part of an infection in an ecosystem.

control strategy census

Control Strategy

The type species of PNEUMOVIRUS and an important cause of lower respiratory disease in infants and young children. It frequently presents with bronchitis and bronchopneumonia and is further characterized by fever, cough, dyspnea, wheezing, and pallor.

human respiratory syncytial virus

Infection by an etiologic agent that can be passed between animals and humans.

Zoonotic Infection

Zoonotic infection

An intentionality directed at future participation in a vaccination.

vaccination intent

Vaccination Intent

a population treatment census that is about one or more vaccinations of organisms in a population

vaccination administration census

Vaccination Administration

Age-Stratified

Vaccine preventable diseases are those infectious diseases that can be prevented by vaccination

vaccine-preventable Disease

Vaccine-Preventable Disease

A treatment that consists of the administration of antigenic material to stimulate an individual's immune system to develop adaptive immunity to a pathogen.

vaccination

Vaccination

A vaccination against respiratory syncytial virus via the administration of the monoclonal antibody nirsevimab

vaccination with nirsevimab

Nirsevimal Vaccination

An organism of a particular biological taxon that is the bearer of an infectious dispositions towards an organism of a different particular biological taxon.

pathogen

Pathogen

Software is a plan specification composed of a series of instructions that can be interpreted by or directly executed by a processing unit.
