Beware of morning mosquitoes

Bed netting is of little use in preventing dengue since dengue mosquitoes are most active during the daytime, warn city doctors with the arrival of the monsoon in the city.

In an advisory issued by the Indian Medical Association (IMA) for the public, it said that “staying indoors in well-screened or air-conditioned buildings during the day can reduce the risk of exposure”.

Tips

IMA’s Dr. K.K. Aggarwal said: “When outside, one should wear clothing that reduces the amount of exposed skin and should use an effective mosquito repellent, such as N, N–diethyl–metatoluamide (DEET).’’

Dramatic plasma leakage can develop suddenly, and therefore, substantial attention has been given to early identification of patients at higher risk of shock and other complications.

Maximum risk

The Association in its release noted that the duration of illness is vital.

“The period of maximum risk for shock is between the third and seventh day of illness. This tends to coincide with resolution of fever. Plasma leakage generally first becomes evident between 24 hours before and 24 hours after the fever is over. The alarm signs include severe abdominal pain, persistent vomiting, abrupt change from fever to hypothermia, or abnormal mental status, such as disorientation,’’ noted the release.

Doctors add that patients with suspected dengue with no indicators for an emergency can be safely managed on an outpatient basis as long as close clinical observation is assured. Daily outpatient visits may be needed to permit serial assessment of blood pressure, platelet count, etc.

“A patient should be hospitalised under the following conditions: Blood pressure <90/60 mmHg and platelet count <50,000/mm3, among others,’’ said Dr. Aggarwal.

App launched

Meanwhile the Central health ministry has recently launched a mobile app for prevention of dengue. The app is aimed at providing awareness and empowering the community members to contribute towards prevention of dengue.
