Three-month-old Rahaf Abu Assi died of fatal complications related to influenza in the strip's southern city of Khan Younis, Palestinian Health Ministry spokesman Ashraf al-Qodra told The Anadolu Agency.
Abu Assi died shortly after being taken to a Khan Younis hospital after suffering respiratory failure, al-Qodra said.
At least ten Palestinians were slightly injured in the Gaza Strip one day earlier after a storm, dubbed "Huda," hit the embattled coastal enclave, local authorities said.
Most of the injuries were minor, caused by flying debris from homes destroyed during Israel's 51-day military onslaught last summer, according to official accounts.
Dozens of Palestinian families have reportedly left their homes in several parts of the coastal strip in anticipation of flooding amid the ongoing cold spell.
Gaza City's local authorities had said the cold spell could cause a "humanitarian disaster," as the city's war-battered infrastructure is largely unable to withstand heavy rainfall.
Already underdeveloped as a result of Israel's seven-year-long blockade, the Gaza Strip's rickety infrastructure sustained further damage during Israel's devastating offensive last July and August.
In December of 2013, thousands of Gazan families were displaced when a severe cold snap brought torrential rains that flooded entire neighborhoods.
Over 2,160 Palestinians were killed – and some 11,000 injured – during Israel's seven-week-long summer offensive, which, according to Palestinian government figures, also cost the Gaza Strip some $5 billion in economic losses.
