Our disease surveillance system needs to be reviewed because often the first case is detected in a private health center. This is the statement of Dr. Deoraj Caussy. He just retired from the Department of Health, where he was a consultant in the field of epidemiology and virology. He is currently a senior lecturer in epidemiology, public health and the environment at the University of Technology (UTM), Open University and the University of Mauritius (UoM).
Why is Mauritius more vulnerable to mosquito-borne diseases?
This gap results from several reasons. First of all, because Mauritius is a tropical country located between two continents, where mosquito-borne diseases prevail. Since the beginning of the year, we have experienced alternate rains and high temperatures due to climate change. The climate therefore favored the spread of mosquitoes.
Could we avoid the problem that currently exists in Vallée-des-Prêtres?
The density of mosquitoes and the sale of repellents should indicate the presence of a large population of culicidae. Then, take appropriate measures to avoid the problem we are currently experiencing.
Is there an epidemic of dengue fever in February?
In Asia and elsewhere, including Mauritius, dengue fever shows periodicity. Typically, epidemics have been observed around April and May. The epidemic in February can be explained by climate changes that favor the proliferation of mosquitoes. As soon as the vector appeared, the spread occurred later.
A protocol for the prevention of diseases transmitted by mosquitoes has been introduced. Does Mauritius do enough to fight these diseases or are there other action plans?
During my stays at the Ministry of Health and Quality of Life, I worked with my colleagues to formulate an action plan to combat mosquito-borne diseases. This protocol is well-established because we managed to control the 2009 epidemic and the epidemic of the following years. Cleaning wasteland must be done regularly. Mosquito densities in places where they usually grow should be more effectively controlled. The same applies to places where dengue cases have been observed in the past, they must be closely monitored. It's the guard's supervision. Our disease surveillance system needs review because the first case was detected in a private health center.
There is a psychosis that settled in Vallée-des-Prêtres and among the population in connection with dengue fever. Do you remember how it is sent?
Dengue is a disease that is indirectly transmitted from one person to another by an infected mosquito. The disease is so contagious and not contagious. We will not have dengue, being in direct contact with an infected person, drinking in the same glass or hugging him. This mosquito acts as a mediator in transmission and is thus a vector of dengue, malaria, chikungunya or zika fever.
You do not need to wear a mask or be in contact with a sick person. The only way to protect it is to keep the environment clean and avoid the accumulation of water on the roof of the house or yard, wearing long-sleeved clothing or the use of repellents.
The most affected are Triolet, Pamplemousses and Port Louis
On March 31, 31 cases of dengue were recorded. For now, the epidemic is mainly in the Vallée-des-Prêtres, where, according to the Ministry of Health, over twenty cases out of 31 registered have been identified. The country has unfortunately experienced other similar episodes, the most serious of which dates back to 2009. Taking into account the data of the Ministry of Health, we find that it was mainly the regions of Port Louis and Triolet that were the most interested dengue fever so far. Vallée-des-Prêtres becomes a high-risk community. It should be noted that imported cases of malaria are also recorded each year.
