The data that World Health Organization announces on the 10th reveal, it is 4379 to make a definite diagnosis of a influenza case of first type H 1 N in the whole world, have increased by 939 compared with the previous day. What the virus is spread within short time makes people startled quickly.

However, through an analysis of epidemic situation data of various countries, we can find, the case for the last few days increases the speed and real spread speed of the virus to tally, though the virus real spread speed is very fast, this speed should not receive human exaggeration.

First of all, influenza virus appear, propagate trend is but no global temporarily fast while being regional. According to the data of WHO, there are nearly 300 examples that come from Mexico while counting in the case increased newly in the whole world on the 10th, but from U.S.A. to have 600 more than example, the two add, account for the same day in the world 939 newly-increased majority of case, Mexico and U.S.A. are just the severely afflicated area of this epidemic situation. It means, first type H 1 N 1st influenza virus has not presented the large range in the other areas of the world yet and propagated the situation fast at present, and it is global influenza case count statistics but there aren't data,can't because judge case total numbers global easily whether there aren't virus when being increased sharply.

Secondly, over these days, North America area, especially U.S.A.'s case is counted and increased fast, totally the locality quarantines and accelerates, monitor the result that the measure puts in place. For example American disease accuse of centre count surge, explain to the intersection of U.S.A. and case U.S.A. all state have a checkout equipment at present, a large number of overstocked suspected cases prove that make a definite diagnosis of the case through measuring every day. And WHO's data reveal, by the night of May 9 local time, the definite diagnosis case of U.S.A. is 1639, suspected case is 740. Nearly 600 in these suspected cases of the next day results are made a definite diagnosis of finally, other cases are removed and suspect. The above-mentioned phenomenon proves, influenza patient's figure is increased sharply and measured competence to improve and have something to do with these days.

The newest data of 10 days of WHO still reveal, nearly 4000 suspected patients wait to examine in Mexico. The expert thinks, is accelerating with measuring the speed constantly, it is estimated Mexico makes a definite diagnosis of a patient to count and also rise by a wide margin in the future, this does not directly relate to the virus spread speed.

Certainly, while understand a influenza case of first type H 1 N for the last few days counts the surge reason, we must not ignore the spread ability of virus either. Take U.S.A. as examples, at the end of April, only 11 states make a definite diagnosis of the case sporadicly in U.S.A., but by May 10, the epidemic situation has already been spread to 44 states, making a definite diagnosis of the case counts and reaches 2254. The above-mentioned phenomenon shows, first type H 1 N 1st influenza virus is perhaps very fast in person-to-person spread. U.S.A. disease accuse of centre expect too, U.S.A. 50 state find first type H 1 N 1st influenza make a definite diagnosis of the case, and the case dies in hospital in this disease may increase continuously.

Relevant experts think, first type H 1 N 1st influenza virus has infective the very strong one, according to present clinical symptom, a lot of patient recover already, severity or influence, seem, have whom people afraid originally so terrible of influenza this, but influenza virus is very difficult predicts, will morph with time. Many experts of WHO say too, about first type H 1 N 1st influenza, there are many unknown factors at present before this, still need to maintain sharp vigilance to it.
