From inside the report, we can reach a few crucial information nod:
? Epidemic situation of Hong Kong hives erupts, already had the court in 30 people, achieve several years new tall;
? Hives virus infectivity is strong and preclinical long;
? Much home clinic and illicit home hospital express vaccinal shortage;
? Predicting diagnose case will appear in succession, epidemic situation is short-term inside won't be over.
The disease prevents the hives database that controls a center to show, our country comes 5 years old with 6 months children incidence of a disease is highest.
Although in recent years the result because of long-term immunity, come on on average move after the age, but it still is mom a of the pit of the stomach big stone.
Then, we invited Doctor Shi Tingting, will be told for mom say those things about hives.

★ 1-5 year old the children that have an inoculation passes measles vaccine or had not given hives.
But the baby of 6 months less than is exceptional, because they can obtain passive immunity of mom, produce infection not easily normally.
The because of immune force have an inoculation of not abiding, immunity fails school age children after ★ vaccinal hives is vaccinal or adolescent.
★ immunity function gets low-key children.
Incorporate for example immune system disease (nephrosis is asked for integratedly, systematization lupus erythematosus) , haemal tumour is ill, or short-term inside just had used hormone kind medicaments (if candy is coriaceous depressor of hormone, immunity) etc.
★ does not have the darling with the pregnant mom strange place of immune force to hives.
This kind of circumstance is scarcer.
Do not have the pregnant mom of immune force to hives, do not have before pregnant namely had given hives or not vaccinal pass measles vaccine.

Go up century metaphase, our country hives year hair patient number ever was as high as 900 much; To 2017, send ill number to already was less than 6000.
All these also is attributed to the result of long-term and vaccinal immunity.
At the beginning of 2019, WHO also points out, the ability after the hives of 93-95% have an inoculation when total population is only vaccinal prevents hives effectively to infect.
★ of ★ hives little history
Be in early 2000, the United States once announced to be in the whole nation already " eliminate " hives virus.
However the near future, the United States has been in 10 cities diagnose case of illness of more than 100 hives.
This kind already announced " eliminate " hives, stage a come back.
World Health Organization (WHO) think, vaccinal hesitation and partial area are primary sanitarian weakness is to cause the main reason that hives case of illness rises nowadays.
Here tells a story:
1998 the name is " ileum is lymphatic and nodal colonitis of particularity of proliferous, blame and obstacle of extensive sex development " the article puts forward:
In patients of 12 children bowel stomach trouble that attend an experiment, 9 are diagnosed to suffer from shut disease oneself, and among them the parent of 8 patients says these symptoms is in child have an inoculation appear after MMR is vaccinal.
(MMR vaccine is the associated vaccine that points to hives, parotitis and measles. )
Then the author thinks, it is the cerebrum growth that MMR vaccine caused infection of chronic bowel path to affect a child thereby, cause shut disease oneself.
Then, a lot of parents reject to make MMR of child have an inoculation vaccinal, or defer inject.
Finally, bring about hives to show the trend of resurgence directly.
However, that article place says, it is a rumor!
Vaccine can be brought about far from shut disease oneself.
A research March 2016 shows, nearly 15 years produce 1416 hives in all, have 804 patients among them never have an inoculation is too vaccinal.
As this hives stage a come back, the necessity of group immunity puts forward again, scientific vaccination just is the key that prevents a disease.
So, mom must set according to the country, give darling have an inoculation, do good precaution.
Near future climate is delightful, it is time of good go on a journey, but also had better not take the sends high toward hives area before darling.
