Influenza update – 295 (based on data up to up to 23 Jul 2017)
—————————
Summary
——-
In the temperate zone of the southern hemisphere and in some countries of Southeast Asia, high levels of influenza activity continued to be reported. In Central America and the Caribbean, increased influenza activity was reported in a few countries. Influenza activity in the temperate zone of the northern hemisphere was reported at low levels. Worldwide, influenza A(H3N2) viruses are predominating.

– In temperate South America, influenza activity, severe acute respiratory infection (SARI) and influenza like illness (ILI) indicators decreased in the countries reporting data. Influenza A(H3N2) viruses predominated in the region with some B virus activity reported as well.
– In Southern Africa, seasonal activity appeared to decrease after peaking in week 26, with influenza A(H3N2) being the most detected viruses.
– In Oceania, seasonal influenza activity continued to increase, with influenza A(H3N2) and B viruses present in the region.
– In tropical South America, influenza activity remained low.
– In the Caribbean and Central American countries, respiratory virus activity remained generally low and increased in some countries.
– In East, Southern and Western Asia, influenza activity remained low in general.
– In Southeast Asia, influenza activity continued to be reported, with all seasonal influenza subtypes present in the region. High influenza activity was reported from some countries.
– In Western Africa, low influenza activity was reported in Cote d’Ivoire, Ghana, and Togo, with influenza A(H3N2) and A(H1N1)pdm09 viruses co-circulating in the region. In Eastern Africa, few influenza A(H3N2) virus detections were reported.
– In Northern Africa, no influenza virus detections were reported.
– In Central Asia, there were no updated reports on virus detections or respiratory illness indicators.
– In Europe and North America, little to no influenza activity was reported.

National Influenza Centres (NICs) and other national influenza laboratories from 78 countries, areas or territories reported data to FluNet for the period from 10 Jul 2017 to 23 Jul 2017 (data as of 2017-08-04 04:25:11 UTC). The WHO GISRS laboratories tested more than 58 087 specimens during that time. 9972 were positive for influenza viruses, of which 9149 (91.7 percent) were typed as influenza A and 823 (8.3 percent) as influenza B. Of the sub-typed influenza A viruses, 653 (8 percent) were influenza A (H1N1)pdm09, and 7505 (92 percent) were influenza A (H3N2). Of the characterized B viruses, 173 (58.4 percent) belonged to the B-Yamagata lineage and 123 (41.6 percent) to the B-Victoria lineage.

[2] Cases Surge in Queensland, Australia

The number of lab confirmed flu cases in Queensland has increased by one third, after 3624 cases were reported across the state in just one week.

“For context, that’s the 2nd highest number of weekly notifications of flu ever reported in Queensland, and it’s a one third increase in the total flu numbers in Queensland this year [2017],” Health Minister Cameron Dick said.

The steep increase, the highest number of cases in one week since 2015, has taken the total number of confirmed cases since January [2017] to 14 455.

Mr Dick said Queenslanders could still take steps to prevent themselves from getting the flu, including getting the vaccination and staying home from work if they are sick.

Health Minister Cameron Dick said it was not too late for people to get the flu vaccination. “You don’t have to go to work if you’re sick; you can stay at home and recover from the flu,” he said.

Queensland Health public health executive director Sonya Bennett, from the communicable diseases unit, said the increase in confirmed flu cases showed that there is a “fair bit” of influenza circulating in the community. “It may still rise again the next week or so, as the minister said it’s not too late to vaccinate.”

Mr Dick said people with flu symptoms should think about visiting their GP instead of the emergency department. “If you have a lower level condition, you may have to wait for treatment, because we must give priority to people who require assistance,” he said.

Royal Brisbane and Women’s Hospital emergency specialist David Rosengren said emergency services were “well equipped” to deal with the surge in demand; staff members have also been affected by the winter illness.

“It is certainly very challenging at the moment, when we have a record demand for services,” Dr Rosengren said. “Reserve a visit to the emergency department for occasions when it’s truly needed.”

The vast majority of this year’s [2017] flu cases were influenza A, which Dr Rosengren said was likely behind the heightened demand on emergency services. “75 per cent of our cases this year [2017] happen to be influenza A, which tends to cause a more significant symptom complex for patients than influenza B,” he said.

Dr Rosengren said it was important for people to minimise their contact with other people if they believed they had the flu.

“If you are unwell … with symptoms typical of the flu, please be very conscious of the impact of spreading that around the community, and if you’re unwell, stay at home,” he said.

Dr Bennett said most people would be able to tell whether they had influenza instead of an ordinary winter cold. “I think we’ve all been unwell from time to time and understand when rest … is the best method,” she said. “Or if you’re feeling particularly unwell, can’t get out of bed, not able to eat and drink effectively, those sorts of signs are the indication that you should go and see your doctor.”

With hundreds of thousands of people expected to attend the Ekka show from Friday [11 Aug 2017], Dr Bennett said the best way to avoid picking up the flu along with a show bag was to be vaccinated.

“Like any mass gathering when it is influenza season and gastro season, the best way to protect yourself is to practice good hygiene, so regular handwashing and vaccination are the best protections against the flu,” she said. “I would ask people that are attending any mass gathering to consider those things.”
