Last updated: June 22, 2009
Severe Acute Respiratory Syndrome (SARS)
(WHO figures mentioned as of December 31, 2003)
- SARS affected 26 countries from November 2002 - July 2003.
- The first probable SARS case was recorded in mainland China in November 2002. The disease became widespread in 2003, but it was contained less than four months after it was first recognized as an international threat.
- China (including mainland China, Hong Kong, Taiwan, and the Macao Special Administrative Region) was the most affected country, with 7,429 cases, including 685 deaths.
- According to the 2007 World Health Report, "SARS defined the features that would give a disease international significance as a global public health security threat: it spread from person to person, required no vector, displayed no particular geographical affinity, incubated silently for more than a week, mimicked the symptoms of many other diseases, took its heaviest toll on hospital staff, and killed around 10% of those infected. These features meant that it spread easily along the routes of international air travel, placing every city with an international airport at risk of imported cases."
- There were 14 confirmed SARS cases in the Philippines; two died.
(WHO figures mentioned as of June 2, 2009)
- Human cases of Avian Influenza was reported in 15 countries during the period 2003-2009 (as of June 2, 2009); the most number of cases during this period was reported in 2006.
- The first known instance of human infection was recorded in 1997 in Hong Kong.
- Indonesia was the most affected country, logging 115 deaths out of 141 cases during the period 2005-2009 (as of June 2, 2009).
- There were no human cases of bird flu in the Philippines.
(WHO figures mentioned as of June 19/22, 2009)
- Human cases of Influenza A-H1N1 were first reported in the US and Mexico in late April 2009. The novel virus quickly spread across more than 90 countries/territories/areas in two months.
- The World Health Organization raised the level of influenza pandemic alert on Influenza A-H1N1 from Phase 5 to Phase 6 on June 11, 2009, saying that "the world is now at the start of the 2009 influenza pandemic."
- US is the most affected country so far, with 17,855 cases and 44 deaths as of June 19, 2009.
- The Philippines has 445 cases of Influenza A-H1N1 as of June 22, 2009. A 49-year-old woman with a pre-existing chronic heart disease and who also had the A-H1N1 virus died on June 19, 2009. The Department of Health said the woman died of "congestive heart failure secondary to acute myocardial infarction aggravated by severe pneumonia either bacterial, viral or both." "A(H1N1) is not the cause of death, but the virus could have exacerbated the situation," Health Secretary Francisco Duque III said at a news conference.
