Swine Flu Update: 02/11/2009

Swine Flu Update: 02/11/2009

Summary

Weekly Swine Flu Update for the Week Ending November 1st.





The past few weeks have been something of a medical paradox. Yes, the number of cases is increasing, but it is doing so somewhat more steadily than first anticipated. The full brunt of the highly anticipated ‘second wave’ is more likely to come towards the end of December and into the heat of the winter season. Conversely, while there hasn’t been a terrible spike in the number of cases, more people are being hospitalized with the virus. Hospitals too are beginning to feel the strain. Speaking on BBC 1’s the Andrew Marr Show, the UK’s Chief Medical Officer, Sir. Liam Donaldson said "What we are seeing is that while most people generally get a mild illness, a small proportion of people are getting very serious illnesses”.

And while it doesn’t represent anything like the surge in numbers that some officials had expected by now, the number of new cases last week was still great enough. An estimated 78,000 new cases of the virus emerged – a 50% increase in the week before – and the number of patients requiring critical care shot up to a record 157. An additional 594 individuals needed less intensive hospital treatment. Worst of all by any metric, another 15 deaths were counted, bringing the UK total to 137. Approximately 50% of the new deaths have come as the result of pre-existing conditions.

In the case of the H1N1 vaccine, the postal strikes too, are causing officials some sleepless nights. Over the next few weeks, GPs will be moving on from the vaccination of frontline NHS staff to the first of the ‘priority groups’ – such as pregnant women and people will long-standing conditions. As GPs begin to send out appointment letters, there is concern that post backlogs will lead to missed appointments and delayed vaccinations for those individuals most in need of immunity. Commenting on the concerns, Donaldson said: "We are a little bit worried about the postal strike because GPs send their letters out, letters of appointment, so we are working very hard to try and get around that, ensuring that people get their appointments in time."

As we move further into the winter season, the concern over hospital resources is likely to intensify further, as critical care facilities come under increasing levels of strain. Already, several intensive care units are being tested under the pressure. The numbers are only likely to grow as the weeks and months pass. Notwithstanding Donaldson’s “plans to expand them [beds]” over the coming months, he also warned that "the intensive care beds are [already] under a lot of pressure”. Yet, as a pause in the surge of cases presents itself, medical officials will be presented with greater time to administer the vaccine in advance of the real ‘second wave’. “The good thing about the situation at the moment is we are getting a bit of breathing space”, said Donaldson. The challenge is to make the most of it.









“In the temperate zone of the northern hemisphere, influenza transmission continues to intensify marking an unusually early start to winter influenza season in some countries. In North America, the US, and parts of Western Canada continue to report high rates of influenza-like-illness (ILI) and numbers of pandemic H1N1 2009 virus detections; Mexico has reported more confirmed cases since September than during the springtime epidemic. In Western Europe, high rates of ILI and proportions of respiratory specimens testing positive for pandemic H1N1 2009 have been observed in at least five countries: Iceland, Ireland, the UK (N. Ireland), Belgium, and the Netherlands. Many other countries in Europe and Western and Central Asia are showing evidence of early influenza transmission, including in Spain, Austria, parts of Northern Europe, Russia, and Turkey. In Japan, influenza activity has also increased sharply, especially on the northern island, approximately 10 weeks ahead the usual start of the winter influenza season.

Pandemic influenza transmission remains active in many parts of the tropical zone of the Americas, most notably in several Caribbean countries. Overall transmission continues to decline in most but not all parts of the tropical zone of South and Southeast Asia

Little influenza activity has been reported in temperate region of the southern hemisphere since the last update.”
