HONG KONG (Reuters) - A scarlet fever epidemic has broken out in
parts of southern China, killing a child in Hong Kong and making
hundreds sick and health authorities said on Tuesday the outbreak
may get more serious in weeks ahead.
"Mainland China and Macau are also suffering from unusually high
numbers of scarlet fever cases and we believe it may be a regional
phenomenon," a spokeswoman for the Health Department in Hong Kong
said.
"The outbreak hasn't shown signs of slowing down and we may
continue to see more cases this summer."
Scarlet fever is caused by group A streptococcus bacteria and it
mostly affects children below the age of 10. It is spread through
contact with contaminated respiratory secretions.
Patients develop fever, a sore throat and break out in a red rash
on their trunk, neck and limbs. It can be treated with antibiotics
but complications can result in shock, heart and kidney illnesses.
Hong Kong has had more than 419 cases of scarlet fever this year,
by far the highest number in years.
Cases in Hong Kong were up 4.5 fold compared with the same period
last year. A seven-year-old girl died in late May and two boys,
age 6 and 11, developed complications but they are now in stable
condition.
Cases in China and Macau were up 2.6 and 4.7 fold respectively,
according to Hong Kong's Center for Health Protection (CHP).
Clusters of cases were found in kindergartens, primary schools and
childcare centers in Hong Kong.
Scientists in Hong Kong who isolated the scarlet fever bacteria in
a six-year-old boy found a slight change in its genetic structure
which may have enhanced its ability to spread, the Health
Department said in a news release.
Scientists at the University of Hong Kong will analyze bacteria
samples from other patients to see if they can shed more light on
the epidemic, the department said.
Half of group A streptococcus bacteria in Hong Kong are resistant
to the antibiotics erythromycin and clindamycin, but they are all
susceptible to penicillin, according to the CHP.
