Are arbovirus infections emerging infectious diseases?
Yes, many are increasing as people move into previously undeveloped areas where the viruses and their hosts live. How can arbovirus infections be prevented? Prevention centers mainly on public health action to control mosquitoes and on individual action to avoid mosquito bites. Community mosquito-control programs can reduce mosquito populations by applying pesticides and draining standing water. Individuals can avoid being bitten by mosquitoes by taking these prevention steps: • If possible, stay inside between dusk and dark. This is when most types of mosquitoes are most active in their search for food. • When outside in mosquito-infested areas, wear long pants and long-sleeved shirts. • Spray exposed skin with an insect repellent. • Screen homes to prevent mosquitoes from entering. • Remove old tires and other water-holding containers from around homes. These can provide breeding sites for mosquitoes. Vaccines are available for yellow fever and Japanese encephalitis.
