This transmission electron micrograph (TEM) depicted Russian influenza-A H1N1, (A/USSR/90/77 strain), virions, which had been magnified 189,000x.
Influenza type A viruses are divided into subtypes based on two proteins on the surface of the virus. These proteins are called hemagglutinin (H) and neuraminidase (N). The current subtypes of influenza A viruses found in people are A(H1N1) and A(H3N2). Influenza B virus is not divided into subtypes. Influenza A (H1N1), A(H3N2), and influenza B strains are included in each year's influenza vaccine.
Influenza types A or B viruses cause epidemics of disease almost every winter. In the United States, these winter influenza epidemics can cause illness in 10% to 20% of people and are associated with an average of 36,000 deaths and 114,000 hospitalizations per year. Getting a flu shot can prevent illness from types A and B influenza.
Influenza type C infections cause a mild respiratory illness and are not thought to cause epidemics. The flu shot does not protect against type C influenza.

This negative-stained transmission electron micrograph (TEM) depicts the ultrastructural details of a number of influenza virus particles, or “virions”. A member of the taxonomic family Orthomyxoviridae, the influenza virus is a single-stranded RNA organism.
The flu is a contagious respiratory illness caused by influenza viruses. It can cause mild to severe illness, and at times can lead to death. The best way to prevent this illness is by getting a flu vaccination each fall.
Every year in the United States, on average:
- 5% to 20% of the population gets the flu
- more than 200,000 people are hospitalized from flu complications, and
- about 36,000 people die from flu. Some people, such as older people, young children, and people with certain health conditions, are at high risk for serious flu complications.
Influenza A and B are the two types of influenza viruses that cause epidemic human disease. Influenza A viruses are further categorized into subtypes on the basis of two surface antigens: hemagglutinin and neuraminidase. Influenza B viruses are not categorized into subtypes. Since 1977, influenza A (H1N1) viruses, influenza A (H3N2) viruses, and influenza B viruses have been in global circulation. In 2001, influenza A (H1N2) viruses that probably emerged after genetic reassortment between human A (H3N2) and A (H1N1) viruses began circulating widely. Both influenza A and B viruses are further separated into groups on the basis of antigenic characteristics. New influenza virus variants result from frequent antigenic change (i.e., antigenic drift) resulting from point mutations that occur during viral replication. Influenza B viruses undergo antigenic drift less rapidly than influenza A viruses.

This Centers for Disease Control microbiologist was shown here delivering tissue culture specimens into a microtiter plate using an instrument know as a pipetter. The culture samples were to be tested for the presence of the influenza virus.
The presence or absence of influenza virus would be determined by using an agglutination test. If it involved the agglutination, or clumping of red blood cells (RBCs), the phenomenon is known as hemoagglutination.
Diagnostic tests available for influenza include viral culture, serology, rapid antigen testing, polymerase chain reaction (PCR), and immunofluorescence assays. Sensitivity and specificity of any test for influenza might vary by the laboratory that performs the test, the type of test used, and the type of specimen tested. Among respiratory specimens for viral isolation or rapid detection, nasopharyngeal specimens are typically more effective than throat swab specimens. As with any diagnostic test, results should be evaluated in the context of other clinical and epidemiologic information available to health-care providers.

This 1968 photograph depicted Penny Gentry, a Centers for Disease Control laboratorian, as she was inoculating 10-day-old embryonated chicken eggs with specimens that were suspected of containing influenza virus.
After inoculation, the culture was incubated for two to three days, in order to facilitate the multiplication of suspected virus particles. If a virus multiplies, it is then identified by using a serological procedure to determine the influenza type.

This transmission electron micrograph (TEM) of an ultra-thin specimen revealed some of the ultrastructural morphologic features seen in 1918 influenza virus virions. The prominent surface projections on the virions are composed of either the hemagglutinin, or neuraminidase type of glycoproteins.
Composed of what looked like dots or tubules, was a dense envelope known as a “capsid”, which surrounded each virion’s nucleic acid constituents.

Ms. Beverly Lawrence, former Administrative Assistant in the Respiratory Virus Infections Unit at the Centers for Disease Control and Prevention, was shown here in this 1968 photograph handling test tubes containing frozen throat swab specimens that were to be tested for influenza.
Because the symptoms of influenza can be similar to those caused by other infectious agents, the disease can be difficult to diagnose based on clinical symptoms alone. A number of tests can help in the diagnosis of influenza, but testing does not need to be done for all patients. During an outbreak of respiratory illness, testing for influenza can help determine if influenza is the cause of the outbreak.

Rebecca Harwell, a former Centers for Disease Control microbiologist in the Respiratory Virus Infections Unit, was shown in this 1968 photograph inoculating a tissue culture in hopes of isolating influenza virions from a throat swab.
After inoculation, the culture was incubated for five to seven days allowing for the possible multiplication of any virions present. If the influenza virus multiplied, it was then identified by using a serological procedure that would determine its serotype.

This 1980’s photograph, taken within a Centers for Disease Control influenza testing laboratory, showed a laboratorian entering data into an influenza-specific database while seated at a computer workstation.
Due to the potentially high degree of pathogenicity, with accompanying poor outcome, tracking the locations, and spread of the influenza virus is of the utmost concern for healthcare providers on the front lines of treatment, and epidemiologists who analyze collected data in order to halt the spread of disease. The computer has made the entrance of data, and its subsequent high degree of accessibility, extremely valuable as a tool to gather and disseminate epidemiologic information that can then be used in the control of this as well as other illnesses.

Dr. Steven R.

Nebraska Governor Pete Ricketts speaks, Feb. 6, 2020, during a press conference at the University of Nebraska Medical Center campus on the state’s support of passengers arriving in Nebraska from China. With approval by the Department of Defense, the Nebraska National Guard is providing unoccupied lodging quarters with 85 rooms, and three other vacant buildings to support a federal Health and Human Services request. DoD installations are only providing housing support. DHHS is responsible for all care, transportation and security of the travelers.
