Re: H7N9 discussion thread: recent increase in cases, January 24, 2014+

temperature is down again, higher temp. and humidity may slow down
the outbreak, we saw that with H7N9 in 2013 and with other flu
(or/and is was from closing the life markets, this is debated)

however, it restarted in Dec.,Jan. with colder temps
(or/and because of increased trade due to NewYear celebrations)

last 7 days:
Shanghai,max.temp.:14-18-20-25-11-09-05 C
Shanghai,rel.humidity:84-86-78-68-95-78-55 %
Hongkong,max.temp.::24-23-25-24-25-26-21 C
Hongkong,rel.humidity:54-64-62-76-71-63-73 %


while the total number of cases is stable - no longer increasing -
cases in the South in Guangdong are increasing

Guangdong has a different virus, reassorted with GD-H9N2, see: http://www.flutrackers.com/forum/showpost.php?p=523520&postcount=29

Thanks for further explaining your temperature post.

I asked you in an email about your comment that Guangdong has a different virus; you gave permission for me to share your following reply (could you explain the "2 years 2 directions" thing):

"sequences were published the last days, see my H7H9-thread

it reassorted with HK-like H9N2, only 3 segments are our old H7N9

HK-H9N2 is quite different from Shanghai

segment 3:
204 44 2151 9456 >KF260367,A/chicken/Hong Kong/FY64W/2010,2010//,Hong Kong,H9N2
44 differences, with 5-6 per year , 4 years 1 direction , 2 years 2 directions ---> common ancestor in 2008

maybe better adapted to HK-climate

showing that H7N9 is capable to reassort with similar strains
so far it just occasionally grasped one new segment, now 4-5 new segments"
