Review of the severe 2017-18 flu season shows reduced vaccination

Dissolve its assessments of the latest flu season, the American Centers for Disease Control and Preventative Treatment (CDC) said the flu was severe, with exceptionally high diseases, hospital stays and deaths for the worst season since the 2009 H1N1 Pandemic

. CDC also said in a separate update that an annual survey suggests that coverage of influenza vaccination decreased last season in adults.

At the same time, with the nation only a few weeks in the 2018-19 season, the flu levels are low, with all three strains circulating, according to the CDC’s latest weekly FluView report today.

Most serious non-pandemic season

Last year, influenza activity began to rise in November and remained at high levels for several weeks in the first part of 201

8. H3N2 was the predominant tribe in February, with influenza B becoming more common in March, which is not uncommon for the latter part of the flu season.

Based on its modeling calculations, the flu reduces 48.8 billion on humans, resulting in 22.7 million clinic visits, 959,000 hospital homes and 79,400 deaths.

For comparison, CDC estimates that 60 million people were affected in 2009 The H1N1 pandemic and 2017-18 exceeded all other recent non-pandemic influenza seasons seriously.

CDC saw high levels of influenza hospitalization among the very young and very old, a pattern that it usually sees with the flu. However, it is said that hospital stays for all age groups were the highest seen since 2005 when it began to include all age groups in hospital flu monitoring.

“Our estimates of hospitalization and mortality in the 2017-2018 flu season continue to show how severe influenza virus infection can be,” said CDC. Elderly adults accounted for 70% of hospitalizations and 90% of deaths, stressing how seniors are particularly vulnerable for severe influenza.

In an aging population, a group usually has the lowest influenza vaccine affected the flu caused an estimated 10 300 deaths.

When last year’s flu season was terminated, CDC reports on infant mortality reported the highest for a non-pandemic years since the agency began to track them in 2004. Additionally, the agency said the 183 reports it received for 2017-18 is probably an underestimate because not all children whose deaths are related to the flu were tested.

On the basis of hospitalizations and death certificates, causes of deaths in Patients who were not and were not in hospital were CDC estimates there in reality more than 600 infantile deaths.

Reduces Vaccine Infection In Adult Flu

An ongoing telephone survey that CDC uses to assess various health conditions and risk behaviors in adults indicates that the flu vaccine coverage in the age group lasts 37.1%, reflecting a decrease of 6 , 2 percentage points from the previous season and the lowest level in the last seven seasons.

However, CDC urged caution in interpreting the results, given the self-reporting of vaccination status and the fact that its early estimates from other data sources did not show a decrease in the uptake.

Its estimation from the behavioral factor monitoring system (BRFSS) suggested that although vaccine coverage varied by age and state, the level decreased in all age groups and most states. The coverage varied greatly from the state, from 29.2% in Louisiana to 46.3% in West Virginia. The level declined in 37 states compared with the previous season and remained steady in 13 states and the District of Columbia. When researchers looked at changes in ethnic group, flu vaccine decreased coverage for all but American Indians / Alaska indigenous people.

Despite the limitations of data sources used to estimate influenza intake in adults, the main message is still that coverage remains low in this age group, with only about 4 in 10 reporting vaccination.

“Since the 2018-19 season is ongoing, it is important that suppliers prioritize influenza vaccination for their patients,” said CDC. “This includes client reminders when access to influenza vaccine becomes available, evaluates vaccination status at each visit, makes an effective vaccination recommendation and offers the vaccine.”

Current Activity Still Low

In its weekly report covering influenza activity by CDC, disease activity was still low nationally, with only four states reporting local influenza activity: Massachusetts, New Hampshire, North Dakota and Oregon.

All three strains circulate, although 2009 H1N1 is the most commonly identified virus.

Clinical visit to flulic disease last week was 1.5%, well below the national baseline of 2.2%. All CDC regions were below their specific baseline.

The proportion of deaths from pneumonia and influenza was 5.3%, below the epidemic threshold of 5.9%. No new pediatric influenza deaths were reported, to keep the sum on one so far.

In clinical laboratories, the proportion of respiratory samples was positive for flu 0.6%.

CDC recommends that everyone is 6 months old and older vaccinated against influenza in late October.
