"Please find below the latest WHO information on PANDEMIC (H1N1) 2009 – please distribute the following information widely.


The Ministry of Health has confirmed the first two case of Pandemic (H1N1) 2009 in Timor-Leste as of 3 August 2009. The results were confirmed at the World Health Organization (WHO) collaborative laboratory in Australia .

Both cases have been discharged from the hospital after spending an appropriate time in the isolation ward at NHGV. They have completed a course of treatment of Tamiflu and the follow up epidemiological investigation found no secondary cases among the close contacts of the cases.

The Ministry of Health continues to remain vigilant and will strengthen surveillance measures designed to detect and treat cases early.

The Government will be focusing on:
  • Providing guidance for people to protect themselves and their families;
  • Taking care of the sick; and
  • Working closely with the WHO and following developments in scientific and clinical issues.

WHO recommends people practise a few basic self-protective measures:
  • wash your hands with soap (or ash) frequently
  • cover your sneezes and coughs
  • stay home (including from work) when ill
  • maintain a distance of 1 metre from people with influenza-like symptoms (fever, cough, sneezing or sore throat).

Cases of Pandemic (H1N1) 2009 have been reported in more than 160 countries. WHO’s understanding continues to evolve as more countries become affected and the spread continues in countries that have been affected for sometime. Majority of cases are still among younger people with median age of 12-17 years (based on data from Canada , Chile , Japan , UK and US). Some reports suggest that persons requiring hospitalisation or with fatal illness may be slightly older. As disease expands, average age is increasing slightly. This may reflect the situation where earliest cases occurred as school outbreaks and later expanded to community.

Risk factors

Cardiovascular disease, respiratory disease including Asthma, diabetes and cancer are considered as risk factors. A recent report suggests that obesity may be another risk factor. There is accumulating evidence suggesting that pregnant women are at higher than young healthy women (NB: Pregnancy is among the at-risk conditions for seasonal flu as well). WHO is not recommending postponing pregnancy in relation to the H1N1 pandemic.

Vaccine development

Development of new candidate vaccine viruses by WHO network is continuing to improve yields (currently 25-50% of normal yields for seasonal influenza for some manufacturers). Four new candidate vaccine viruses are available for distribution and evaluation of the growth property is under way. Vaccine manufacturers are expected to have their vaccines for use beginning in September. A number of companies are working on pandemic vaccine production and have different timelines.

WHO has received reports of five oseltamivir (Tamiflu) resistant to pandemic (H1N1) virus from four countries to date – Denmark , Japan(2 cases), Hong Kong SAR China, and Canada . We have not heard that the resistant virus has been transmitted beyond these patients. This is something WHO has been expecting to happen and happens for seasonal influenza and avian influenza infection. All these resistant viruses have been sensitive to the second neuraminidase inhibitor, zanamivir

H1N1 2009 pandemic compared to seasonal flu or other pandemics

Seasonal flu is different from pandemic flu in the sense that it is not affected in the same period or the same population group. It is too early to compare this pandemic with other pandemics because we are only beginning to see how this pandemic is evolving.
