To the Editor—The recent report on 'co-infection
of influenza B and
Streptococcus' by Lam et al
1 is
very interesting. They reported "four cases infected
with influenza B and streptococci that gave rise to
severe pneumonia" and mentioned that "this is the
second case report of severe invasive pneumococcal
pneumonia secondary to influenza B infection."
1
Indeed, both influenza B and
Streptococcus infections are important infectious diseases that are
encountered worldwide. In fact, there are more than
two previous publications reporting the concurrent
infection of influenza B and
Streptococcus.
2 3 In the
report by Aebi et al,
2 three cases were document and
additional four cases were presented in the report by
Scaber et al.
3 Hence, the claim by Lam et al
1 should
not be correct. Nevertheless, in all reports, the
clinical features of the pneumonia were serious and
sometimes fatal. As Lam et al
1 suggested, physicians
should increase awareness of possible concurrent
infection in the present era of emerging influenza.

To the Editor—Our report concerned severe
pneumonia due to co-infection of influenza B and
streptococcus. Scaber et al
1 described a series of
19 invasive streptococcal infection cases affecting
a variety of organs. Scaber's objective and emphasis
were different from that of Aebi et al
2 and our report.

Moreover, Scaber et al1 did not provide much
clinical details of the patients, such as laboratory
investigation findings and complications. Therefore,
their article
1 was not included in our reference list.
We would nevertheless like to thank Drs Joob and
Wiwanitkit for their comments. The mentioned
studies certainly enhance awareness of this serious
co-infection of influenza B and streptococcus and
alert physicians and other health care professionals.
