An increasing number of cases of worrying meningococcal disease prompted the research agency Crovn ESR to increase its monitoring.
Cases from Disease Illnesses rose from five in 2016 to 12 last year and 25 to this year. The latest case, which includes Wellington's over 60 years, was discovered today by Public Health Officer Jill Shervood. There were also six deaths this year, three of them in Northland for the last three and a half months.
The Ministry of Health is considering an immunization program for Northland in response and does not provide any comments as this happens.
ESR monitors and reports on meningococcal disease, including case numbers, types of circulatory diseases and trends. Meningococcus B is the most common fear in this country, but MenV, which is rarely, but virulent, is growing here and abroad. Dr Sherwood said that the ESR first noticed an increase in MenV last year and increased its monitoring.
She said that last year the Ministry of Health reported on a two-week basis, but will now report weekly.
Dr. Shervood added that while MenB remains the dominant effort in this country, in 43 cases until now this year, New Zealand could monitor trends in other countries, including Australia, where MenV became the dominant effort in 2016.
"Although the number of MenV cases in New Zealand remains relatively low, there is a growth trend in notifications and a recent change in the type of sequence similar to the UK, Australia and Canada."
Dr. Shoredod said that the numbers of cases in other countries were higher than in New Zealand, but was similar, leading to increased monitoring.
"We know what's going on in Northland. We want to make sure we're sure we're going to make changes in other areas in New Zealand."
ESR data on meningococcus B and V disease this year show 7 cases in Northland; three in Vaitemata, Auckland and Canterbury; two in the county district board of Lakes County in Rotorua, Wellington and Porirua and Southland and Otago; and one case in both counties Manukau and Vanganui.
Dr Sherwood said many people carry meningococcal bacteria in the nose and throat, "and we know that probably at least 15 percent of the population is carrying it at any stage."
She said that bacteria do not attack or cause illness in most people, adding why it causes serious illness in a small population is not well understood.
"When we see the numbers of cases, it is assumed that the speed of driving in the background has become greater. And so we have more numbers in Australia, we worry that this means that people who visit Australia or come from Australia … have more chances that we will end up with a higher speed of transportation and an increase in the disease rate here, which is why we have started to follow closely. "
Healthcare institutions here said they were at a loss to understand the rise in MenV in this country. Dr Sherwood said it could be linked to increasing efforts around the world.
"We do not know for sure, you can not prove it, but certainly this form is concerned."
