How many people died from the flu in 2017 and 2018 in the US?
The overall burden of flu for the 2017-2018 season was an estimated 41 million flu-related illnesses, 19 million flu-related medical visits, 710,000 flu-related hospitalizations, and 52,000 flu-related deaths (Table 1).
How many people get the flu each year?
During the 2021-2022 influenza season, CDC estimates that influenza was associated with 9 million illnesses, 4 million medical visits, 10,000 hospitalizations, and 5,000 deaths.
In the U.S., flu season usually starts in the fall and lasts until spring. Flu season in the U.S. usually peaks in January and February and ends by April or May. The CDC recommends that everyone over the age of 6 months old gets a yearly flu vaccine.

2018/2019 INFLUENZA REPORT

Overview

Figure 1: Number of cases, hospitalizations, ICU admissions and deaths, by week virus identified, NL, 2018/2019

There were 1033 laboratory-confirmed cases of influenza during the 2018/2019 season. Of these cases, there were 270 hospitalizations, 63 ICU admissions and 27 influenza-related deaths (Table 1). This season peaked in week 14 (first week of April), 4 to 6 weeks later compared to the

5-year average (Figure 1).

Influenza A was the predominant virus circulating across all regional health authorities, accounting for 98.9% of all laboratory-confirmed cases (Figure 2). Adults aged 20-64 years accounted for the largest proportion of cases overall (45%), followed by adults aged 65 and above (33%). Those less than 20 years of age accounted for 23% of lab-confirmed cases (Figure 3). The average age of confirmed cases was highest for those who had died:

Cases, mean: 47.5 years

Hospitalizations, mean: 57.6 years

ICU admissions, mean: 56.6 years

Deaths, mean: 74.4 years

Over half (59.5%) of laboratory-confirmed cases were female, and they accounted for 53.3% of hospitalizations, 60.3% of ICU admissions and 48.1% of deaths (Table 1). 0 20 40

2018-2019 Season

Influenza Strain

Influenza A was the predominant strain during the 2018/2019 season in NL. Of cases,

98.9% were influenza A and 1.1% were influenza B (Table 2). Fewer influenza B detections

have been reported this season compared to recent seasons. Across Canada, influenza A accounted for 95.3% of laboratory-confirmed cases, of which subtype A(H1N1)pdm 09 was the most common. Over the 2018/2019 season, the National Microbiology Laboratory tested influenza A and B viruses for antiviral resistance: 4 viruses were resistant to oseltamivir (Table 3).

Immunization

Influenza immunization history is collected (when available) for lab-confirmed cases that result in a hospitalization or death. Of these cases, 15.6% reported receiving the

2018/2019 influenza seasonal vaccine, 61.9% reported no immunization, and 22.5% had

unknown immunization status. In NL, influenza vaccine is offered to all individuals six months of age and older. The flu vaccine is especially important for those who are at high risk of complications from the flu such as individuals with underlying health conditions. For more information visit http:// The National Microbiology Laboratory (NML) characterized antigenically 2274 influenza viruses (378 H3N2, 1656 H1N1 and 240 B viruses) during the 2018/2019 influenza season. The majority of H3N2 and H1N1 viruses were antigenically similar to the vaccine strain. Of the influenza B viruses characterized, 30% were antigenically similar to one of the two vaccine components in the quadrivalent flu vaccine.

Note: The NML receives a proportion of the influenza positive specimens from provincial laboratories for strain

characterization and antiviral resistance testing. Strain characterization data reflect the results of hemagglutination

inhibition (HI) testing compared to the reference influenza strains recommended by WHO.

There were 150 respiratory outbreaks during the 2018/2019 season. Of these, 37 were confirmed influenza A outbreaks (Figure 4). There were no confirmed influenza B outbreaks. Outbreaks occurred in all regions, peaking in March. Figure 4: Number of confirmed influenza outbreaks reported in Canadian Network for Public Health Table 4: Number of positive respiratory virus specimens, by type, NL, 2018/2019 season1 In addition to influenza, there were a number of other respiratory viruses circulating during the 2018/2019 season (Table 4). The most predominant virus other than influenza was RSV.
