Influenza A (H1N1) Swine Flu - Update Eighty-five

 

Hawke’s Bay, Taranaki and Hutt DHBs are sending information through existing community networks as well as using iwi and community radio to spread the messages. 

 

Waikato DHB has produced posters which are being distributed extensively throughout the region, reminding people how to protect themselves and others. 

 

Capital and Coast DHB is screening staff with symptoms so they do not transmit illness to patients and has posters above each bed reminding visitors to go home if they have any flu-like symptoms. 

 

“That message is a very important one,” says Dr McGrath. “We need to protect the patients already in hospital and ensure our front-line medical staff are healthly so they can treat patients safely. If you have flu-like symptoms, please do not visit people in hospital. However, if you do need to visit, please contact the ward first to discuss what to do.”

 

While the number of confirmed cases in New Zealand continues to rise, the Ministry of Health says most people who develop non-seasonal Influenza A (H1N1) swine flu will have mild to moderate symptoms and will recover at home without needing medical treatment. 

 

However, as with any influenza, a small number of people will develop more severe symptoms and they should phone Healthline (0800 611 116) or their family doctor for advice.

 

Dr Fran McGrath, Deputy Director of Public Health, says people who already have existing health conditions, such as serious respiratory or heart illnesses should also phone their GP early if they get the flu 

 

“Looking at cases from other countries, many people who develop serious illness related to the non-seasonal influenza already have serious underlying medical problems, the influenza virus can worsen these underlying health conditions." 

 

"In some countries, around 2% of cases have developed severe illness", reports Dr Chan, Director General, WHO. 

 

Dr Chan says that, "Most cases of severe and fatal infections have been been in adults between the ages of 30 and 50 years. This pattern is significantly different from that seen during epidemics of seasonal influenza, when most deaths occur in frail elderly people. Many, though not all, severe cases have occured in people with underlying chronic conditions. 

Based on limited, preliminary data, conditions most frequently seen include respiratory diseases, notably asthma, cardiovascular disease, diabetes, autoimmune disorders, and obesity.” 

 

This was the case in Australia where the two reported deaths from non-seasonal Influenza A(H1N1) occurred in patients who had other serious medical conditions.

 

The three most important things New Zealanders can do to protect themselves and others from influenza this winter are washing and drying your hands, covering coughs and sneezes and staying home if you're unwell.
