Between 2012 and June 2017, the Better Public Services programme included a target to reduce rheumatic fever by two-thirds to 1.4 cases per 100,000 people.
How did we do?
In the 12 months ending on 31 December 2017, there were 160 people diagnosed for the first time with rheumatic fever in New Zealand. This represents a 10 percent drop from 177 people in 2012 (4.0 per 100,000) to 160 people (3.4 per 100,000) by 31 December 2017.

The graph above shows the rate of Māori and Pacific people admitted to hospital with rheumatic fever for the first time between 2011 and 2017.
By 31 December 2017, rheumatic fever incidence in Māori had fallen by 28 percent. There was no change in the incidence of rheumatic fever cases in Pacific people.
The following table shows the numbers and rates of people being admitted to hospital with rheumatic fever for the first time in 2017 by age group. It shows that the majority of cases occur in children less than 14 years old.
| Age group | Number | Rate (per 100,000) |
|---|---|---|
| 0–14 years | 96 | 10.5 |
| 15–44 years | 55 | 3.0 |
| 45+ years | 9 | 0.5 |

Note: Rates have not been calculated where there were fewer than four cases. This is because the small numbers will result in unreliable estimates of rates.
Where to from here?
Although the national decrease did not meet the two-thirds reduction target, some DHBs have made good progress in reducing rheumatic fever. Northland DHB has achieved its target to reduce rheumatic fever by two-thirds. Other DHBs that have made good progress in rheumatic fever prevention include Counties Manukau, Hauora Tairāwhiti, Lakes, Hawke’s Bay and Capital & Coast DHBs.
Rheumatic fever prevention will continue to be a focus for the 11 DHBs with a high incidence of rheumatic fever.
The government has allocated $5 million per year until 2022 to these 11 DHBs so they can continue to deliver a balanced mix of rheumatic fever prevention activities to address rheumatic fever and reduce rheumatic fever rates.
