Singapore Enhancing its A(H1N1) Flu Surveillance, Measures Being Implemented

As of 18 June 09, Singapore has 77 confirmed cases of influenza A (H1N1). 75 cases were imported while one appeared to have acquired his infection in Singapore, and another one was a close contact of a confirmed case. So far 27 patients have been discharged.  The remaining 50 patients (22nd - 23rd, 25th - 28th, 31st - 32nd, 34th, 36th - 37th, 39th - 77th cases) are still in the hospital and their conditions remain stable.

As quoted in MOH website:

We must press on with our containment efforts and everyone must play his part.  This is especially so for recent travelers from infected areas.  They must not engage in community activities and come forward immediately for screening and isolation as soon as flu-like symptoms develop.

In Alert Yellow, stringent border controls will still be maintained, with temperature screening at air, land and sea checkpoints.

Measures Implemented:

• Stringent border controls will still be maintained, with temperature screening at air, land and sea checkpoints.
• However, temperature screening requirements and screening for flu-like symptoms and travel history have been lifted at work places, schools, buildings and events.
• At healthcare institutions, the current tighter restrictions will continue to be in place for the time being, especially in high risk areas such as A & E and ICU.

MOH has been monitoring the flu situation in Singapore, to identify the strains of flu virus circulating. With the threat of an Influenza A (H1N1-2009) outbreak, MOH has enhanced flu surveillance to include up to 3 times more samples from both the community (i.e. polyclinics and GPs) and tertiary care (i.e. hospitals).

The flu A positivity decreased from 21.1% in E-week 22 (31 May - 6 Jun) to 19.9% (preliminary) in E-week 23 (7 Jun - 13 Jun).

Based on past trends, there are 2 peaks in flu activity in Singapore, usually in the months of May to June and December to January.

Update on the number of Influenza A(H1N1) Virus Affected Pinoy in Singapore

Based on the daily update from the DFA website, below is the latest statistics:

• A Filipina was tested positive of the A(H1N1) infection per confirmation by the Singapore Ministry of Foreign Affairs


• 10 Filipinos who had close contact with a confirmed A(H1N1) case were quarantined until 15 June 2009, while 3 more added in the list will be quarantined until 19 June 2009


• The total number of Filipinos in Singapore who were reportedly issued Home Quarantine Orders are now twenty-four (24).

Singapore confirmed 11 new cases of influenza A(H1N1)

Further updates from the Ministry of Health:

Singapore has confirmed another 11 new cases (67th to 77th cases) of Influenza A (H1N1), including one who appeared to have acquired his infection in Singapore. The remaining 10 cases involve travelers returning from countries with known community transmission of H1N1. This brings the total number of confirmed cases here to 77.

• The 73rd case is a 26-year-old Malaysian male who is a PR in Singapore.  He departed from Singapore to Kuala Lumpur for work on SQ108 at 1000 hours on 14 June.  Later that evening, he developed symptoms while he was having dinner at a restaurant.  On 15 June, he attended a conference in the morning and went out in the evening.  On 16 June, he sought medical attention at a GP clinic in the early hours and was prescribed antibiotics and paracetamol. He then went back to the hotel and remained there for the rest of the day. He returned to Singapore from Kuala Lumpur on SilkAir MI335 at 1514 hours on 17 June. He was seated at row 19.  When he arrived at Changi Airport, he immediately approached the airport staff and a 993 ambulance was called to send him to TTSH.  Prior to his travel to KL, his last travel out of Singapore was to Hong Kong from 28 May to 1 June 09. He remained well after his trip to Hong Kong.
  
• While investigations continue, our tentative assessment is that he may be our first unlinked local case as he has no travel history to a known infected area.   He could have come into contact with one of the earlier confirmed cases here, since the virus is not native here.  Unless further investigations turn up evidence otherwise, and if more such unlinked cases emerge over the next few days, this would signal the beginning of community spread in Singapore. We have not reached such a stage yet.  We must press on with our containment efforts and everyone must play his part.  This is especially so for recent travelers from infected areas.  They must not engage in community activities and come forward immediately for screening and isolation as soon as flu-like symptoms develop.
  
• Meanwhile, we have alerted our Malaysian counterparts about this case and his activities in KL.

Details of new imported cases

The nationalities of the 10 imported cases are

• 6 Singaporeans
• 1 Singapore PR (Filipino)
• 3 foreigners (1 Filipino, 1 Australian, 1 Canadian)

Of the 10 cases, one was unwell before boarding the flight, while three developed symptoms during the flight. The remaining six cases, who developed symptoms after arrival in Singapore, sought medical treatment or called 993 soon after onset of symptoms. All six stayed home between onset of symptoms and seeking treatment.

Contact tracing is ongoing for all new cases, including for close contacts for the following flights:
