So far this year, Hanoi has recorded a soar in the number of measles patients with 347 cases, but there have not been any hotbeds.
Hanh said 95 percent of the children in the locality have been vaccinated against measles, and the spread of this disease will be contained in April if the immunisation programme is well implemented.
There remain 26 dengue fever cases, down 10.3 percent from the same period last year, while the number of hand-foot-mouth patients has also been brought down by 86.7 percent to 11, he added.
However, Hanoi has seen a slight increase of chickenpox patients with 188 cases so far this year.
The official also warned there is a probability that influenza strains A/H7N9 and A/H10N8 make their way to Hanoi, break out and become an epidemic.
