MidCentral District Health Board region now has its first four confirmed cases of Novel Influenza A (H1N1) 09.
The cases involve a child and adult in Horowhenua, a Pahiatua teenager, and another adult from Palmerston North.
Earlier, another case was confirmed in Marton, which comes under MidCentral Health’s public health services area, but is in the Whanganui District Health Board region.
As a result of these increased cases locally, MDHB has decided to move from the “contain it” phase in its pandemic response to a “manage it” phase from next week, recognising the increase in numbers and moderate severity of the disease.
The cumulative total of confirmed cases in New Zealand is 453, up 36 from 417 yesterday.
Most other District Health Boards have already moved, or are considering moving to, the “manage it” phase.
What happens in the “Manage it” phase and what does that mean?
It is expected about a third of New Zealanders will become ill with this virus over the coming months and for the vast majority it will feel, and be treated, like seasonal influenza.
The difference between Influenza A (H1N1) and seasonal influenza isn’t what it feels like for individual New Zealanders who get sick, but the numbers of people getting sick. This is because it is new and people have not developed any immunity to it.
The high number of cases will stretch and challenge our health system. High infection rates will also mean that a lot of people will be off work sick or looking after sick family members.
Preventing, delaying and minimising the arrival of further cases of infection into New Zealand and the community spread of infection remain the current objectives.
Border management is still a part of the Government’s response and will remain so. Activities at the border will continue, principally providing health information to people arriving in New Zealand and advice as necessary.
The Ministry of Health, and MDHB, will be providing advice and information for the majority of people through:
-
- Healthline phone 0800 611 116
- primary care (ie. professional care received in the community, usually from your GP or practice nurse)
- the internet http://www.moh.govt.nz or www.midcentraldhb.govt.nz
- the media
- in some areas, flu centres or Community Based Assessment Centres (CBACs) will be set up to manage high numbers.
Anyone who is sick should stay in home isolation in order not to spread the virus, but those who are well are not expected to put themselves into quarantine.
But as more cases are confirmed in the community, the focus will need to shift to boosting the way care is provided in the community. The decision on where best to direct the efforts of health professionals is reviewed daily.
What about serious or severe cases?
During the ‘Manage it’ phase, people who become unwell with any type of influenza will need to stay home and look after themselves instead of being assessed by the public health services. Most will not need medical help. For those who feel they need medical help, please continue to phone your General Practice.
Just like seasonal influenza, a small proportion of cases will develop more serious complications, and health services will need to prioritise these cases.
People should ring their General Practice if they develop more serious illness or if they have serious chronic conditions (eg. heart failure, severe lung disease, severe asthma) which put them at risk of a more serious illness.
Treatment with antivirals – Tamiflu and Relenza – may be prescribed for people with more severe influenza or those at higher risk of complications.
The aim is to make sure hospitals can look after those who develop a more severe illness, get complications or have other medical needs.
Being prepared for self care
An important part of the “manage it” phase includes individuals being prepared to look after themselves at home in the same way they would with seasonal flu.
The Ministry of Health is not advising people to cancel social gatherings, sports events and travel. However, there are practical steps that individuals and communities can take to reduce the community spread of the virus. These steps include practising good hand hygiene and covering coughs and sneezes. If you are sick, stay home until you have fully recovered as you can easily spread the germs to others.
