  1. Avoiding rodents (multimammate rats).
  2. Consider all patients as infectious even if signs and symptoms are mild.
  3. All standard, contact, and droplet precautions as well as correct use of appropriate personal protective equipment should be strictly adhered to.
  4. Blood and body fluid specimens from patients with suspected Lassa fever infection should be considered highly infectious. Caution should be exercised when handling such material.
  5. Postexposure prophylaxis with oral ribavirin for contacts with known or suspected Lassa fever infection with risk factors for transmission such as penetrating needle stick injury, exposure of mucous membranes or broken skin to blood or body fluids, and participation in procedures involving exposure to bodily fluids or respiratory secretions without use of personal protective equipment.

Sunlight can reduce weight

A new Northwestern Medicine study has reported that the timing, intensity and duration of exposure to light during the day are linked to your weight.

People who had most of their daily exposure to even moderately bright light in the morning had a significantly lower body mass index than those who had most of their light exposure later in the day.

“The earlier this light exposure occurred during the day, the lower the individuals’ body mass index,” said co–lead author Kathryn Reid, research associate professor of neurology at Northwestern University Feinberg School of Medicine. “The later the hour of moderately bright light exposure, the higher a person’s BMI.”

The influence of morning light exposure on body weight was independent of an individual’s physical activity level, caloric intake, sleep timing, age or season. It accounted for about 20 percent of a person’s BMI.

“Light is the most potent agent to synchronize your internal body clock that regulates circadian rhythms, which in turn also regulate energy balance,” said study senior author Phyllis C. Zee, M.D. “The message is that you should get more bright light between 8 a.m. and noon.” About 20 to 30 minutes of morning light is enough to affect BMI. (Science Daily)

  • People with fair skin that burns easily should protect themselves from skin cancer by limiting sun exposure to 10 minutes or less.
