Every year, spring and summer is the high incidence season of HFMD, so for many parents, some basic knowledge of HFMD must be understood. What are the initial symptoms of HFMD? And some parents also need to ask, is it after vaccination, children will not have HFMD?
Initial symptoms of HFMD
In the early stage of HFMD, children will have fever, cough, runny nose, drool and other symptoms like upper respiratory tract infection. Some children may have nausea, vomiting and other symptoms. After that, oval or shuttle shaped blisters appear on the fingers and back of the toes of the hands and feet. Around the blisters, there is a clear fluid of the erythema blister. The long axis of the blister is consistent with the dermatoglyphics. (this article is exclusively compiled by WYH, editor of sihai.com.

Then the central depression of the blister turns yellow, dries and peels off (desquamation). In addition, there are scattered relatively hard reddish papules or herpes at the end of the fingers and toes.
At the same time, there are also scattered blisters in the mouth, such as lips, tongue, oral mucosa and gingiva. However, the blisters in the mouth quickly break and form a gray white dot or gray white layer of membrane around which there is a red halo. Under the gray white membrane, spot or sheet erosion surface can be seen. (this article is exclusively compiled by WYH, editor of sihai.com.

Is vaccinated, the child won't get hand foot mouth disease?
This is not the case. Experts said that there are more than 20 kinds of viruses causing HFMD. EV71 HFMD vaccine can only prevent HFMD caused by enterovirus 71 infection, but has no preventive effect on HFMD caused by other viruses. However, many severe cases of HFMD are caused by enterovirus 71. After vaccination, even if other viruses cause HFMD, there are few severe cases and deaths.
Similarly, if it is not clear that a child's previous HFMD is caused by EV71, vaccination is still recommended.
