The ITM Annual Colloquia

 

The Institute of Tropical Medicine Antwerp (ITMA) organises each year an international colloquium on a topical subject in global health. It brings together an interdisciplinary audience of scientists, experts and professionals from North and South, and aims at providing an updated overview of the topic as well as recommendations for improved practices and policies.

 

Since 2005, the venue of these annual meetings alternates between the ITM in Antwerp and its partner institutions in the South. The 48th annual ITM colloquium will take place from 3 to 5 December 2007 in Hanoi, Vietnam, in collaboration with the National Institute of Malariology, Parasitology and Entomology (NIMPE). The theme will be “Malaria in the Mekong Region: challenges and opportunities”. The entire colloquium will be conducted in English.

 

Background

 

During the last decade, the Mekong countries have been very successful in reducing the burden of malaria. Strong political commitment, technical expertise and the integration of malaria control in the community-based health system were key elements to this success. The main strategies included prompt diagnosis and treatment, wide coverage and targeted vector control through insecticide-treated nets (ITNs), and indoor residual spraying (IRS). In addition, socio-economic development has substantially contributed to the decline of malaria in the region.

 

Malaria has not yet disappeared, however. In remote and forest settings the transmission rates are still high, as a result of complex interactions between vectors, parasites and humans. Forest vectors typically feed in the early night, making ITNs less effective; moreover, bed nets are not easily adaptable to the lifestyle of forest workers. Migration between endemic and malaria-free areas leads to upsurges of malaria in border areas, access and compliance to prevention and treatment are complicated by social, cultural and political factors. Environmental modifications that affect the distribution and abundance of vectors lead to changes in malaria transmission. Multi-drug parasite resistance has become a regional and global emergency, complicated by the widespread marketing of substandard and counterfeit drugs. The effectiveness of ITNs is compromised by the emerging resistance of mosquitoes to pyrethroids, particularly in Southern Vietnam.

 

 

Objective

 

The colloquium will review these experiences and challenges, with as main objectives to

-         review the current situation

-         identify remaining knowledge gaps

-         formulate strategies for the consolidation and extension of the achievements

-         optimise measures to roll back forest and border malaria

-         examine ways to contain the spread of multi-drug and insecticide resistance.

 

Scientific programme

 

The colloquium will cover the following topics:

·         Current malaria situation in the countries (Vietnam, Cambodia, Laos, Thailand)

·         Vectors:

o        Biodiversity, behaviour, distribution

o        Insecticide resistance

o        Control methods and strategies

·         Forest and border malaria:

o        Risk factors

o        Intervention strategies

o        Cross-border problems

·         Case management:

o        Drug resistance

o        The role of the private sector

o        Community-based monitoring

o        Health information systems

·         Socio-cultural aspects:

o        Migration and mobility patterns

o        Perception of malaria, its treatment and prevention

o        Compliance and health seeking behaviour

·         Monitoring and evaluation

 

The colloquium will be followed by a workshop (6-8 December 2007) on the role of social sciences, especially anthropology in malaria control. The workshop is fully booked and registration has been closed.

 

Registration

 

If you wish to participate, please fill in the online registration form. There is no registration fee but you can only attend if you have registered. Final acceptance of your registration will be based on a proven link with the colloquium topics. Lunch and one dinner during the colloquium are provided free of charge by the organisers. Apart from the invited speakers, participants should, however, book and pay for their own travel and boarding. The meeting will take place in the Kim Lien hotel (website www.kimlientourism.com.vn). For hotel reservation please contact kimlienhotel@hn.vnn.vn or kimlienhotel@yahoo.com, +84 4 8 522 522 or +84 4 5 770 463 (about 35 to 50 US$ /night); the secretariat can also provide you with a list of alternative hotels in various ranges.

Travel information & visa application  

 

IMPORTANT: You are advised to make your travel arrangements as early as possible, as December is the top tourist season in Vietnam and flights and hotels are filling up quickly.

 

Visa:

All foreign participants (except those from Cambodia, Laos and Thailand) travelling to Hanoi for the colloquium need to apply for an official visa using this visa application form. We will do our utmost to help you with your official visa application, but cannot guarantee a successful procedure at this late stage. Do not forget to mention in which Vietnamese Embassy or Consulate you will pick up your visa. Your application will be sent to Vietnam for approval and you will be informed when you can pick up your visa.

 

Flights:

All participants travelling to Hanoi by air will arrive at Noi Bai International Airport, where metered taxis are available to take you to your hotel. Make sure the taxi driver is wearing an official name badge and that the meter is on. The distance to the city centre is 45 km and the transfer will take about 45 minutes. When leaving Hanoi, you will need to pay a 14 USD departure tax (except if this fee is included in your ticket).

 

Hotels:

The meeting will take place at the Kim Lien Hotel (www.kimlientourism.com.vn), a mid-range hotel where a (limited) number of rooms is available for colloquium participants. For hotel reservations please contact kimlienhotel@hn.vnn.vn. The room rates range from 35USD/night for a standard room to 50 USD/night for a deluxe room (breakfast included).

 

A list of alternative hotels in various price classes is available from the colloquium secretariat.

Upon arrival at your hotel, you will be asked to hand over your passport to the receptionist, who will register you at the police office. This is normal procedure and your passport will be returned to you on the next day.

It might be a good idea to make a copy of all your official documents (passport, visa, etc.).

 

CURRENCY

The national currency is the Vietnamese Dong (VND). In most shops and hotels USD are accepted as well. The exchange rate usually applied is 1 USD= 16.000 VND. Euros can be changed at the airport or in banks or jewellers in the city centre.

 

 

TRAVEL HEALTH

 

Yellow fever:  

YELLOW FEVER vaccination is NOT required if you are departing from Belgium. There is no yellow fever in Belgium. If you are travelling from another country where yellow fever can occur (Africa, South America), you should be vaccinated from the age of 1 year.

 

Malaria:  

There is NO risk of malaria in Hanoi. However, if you plan to visit the rest of the country, please consult www.travelhealth.be.

 

Diarrhea:  

DIARRHOEA is a frequent problem when travelling. Even when travelling in good conditions, it is not always possible to avoid it. Please see www.travelhealth.be for more information on travellers’ diarrhoea.

 

Vaccinations:  

Going on a trip is furthermore an ideal opportunity to bring TETANUS-DIPHTHERIA- and POLIOMYELITIS VACCINATIONS up to date.
The WHO advises anyone travelling to Asia, Latin America or Africa, regardless of the duration and the circumstances of their stay, to protect themselves against HEPATITIS A. In a lot of cases vaccination against HEPATITIS B is also advisable.
Please see www.travelhealth.be for more extensive information.
