Having recourse to the Holy Angels is another worthwhile devotion. Start with your own guardian angel, who loves you beyond what you could ever comprehend in this life. Only in the next life will we see just how many dangers and evils have been prevented through our angels' unwavering care and protection. So love... appreciate... and pray to your personal angel each and every day.
And of course, there are the three Archangels - Michael, Gabriel, and Raphael. St. Michael shields us with God's protection; St. Gabriel reveals God's Word; St. Raphael dispenses God's healing. All these are much needed blessings right now so invoke these Holy Archangels frequently - together!

Concerning sacramentals, they are external signs of certain devotions. They primarily differ from the Sacraments (e.g. Baptism, the Eucharist, Confirmation, etc.) in that the Sacraments were instituted by Christ to give us sanctifying grace, while sacramentals are given to us by the Catholic Church to inspire us to live better lives so as to gain graces. Used properly - not superstitiously - sacramentals dispose us to receive favors in soul and body through the authoritative power of the blessing and prayer of the Church. Among the most common sacramentals the Faithful may avail themselves of during these urgent times are...
+ The Crucifix
This is a no-brainer. For me crucifixes are on a level all their own compared to other sacred images, and should be automatic in a Catholic home. If you don't already have one, get one and display it in a prominent place in your house! Use it regularly to meditate on the Passion and invoke the saving power of the Precious Blood.
+ Holy Water
This is "Sacramentals 101". Water universally symbolizes cleansing so Holy Water is commonly used to spiritually purify everything it's prayerfully sprinkled on - persons, objects, and places. The great St. Teresa of Avila (d. 1582) once wrote, "From long experience I have learned that there is nothing like holy water to put devils to flight." Get into the habit of blessing yourself daily with it and sprinkle it weekly within one's home.
+ Sacred Images / Statues
Having statues, icons, and pictures of Jesus, Mary, and the Saints in a home is not only comforting since images effectively convey a sense of presence of the holy persons represented... and they can also channel signal graces. This has been witnessed and documented time and time again throughout history. One tremendous example occurred in Rome, circa 590 - the black plague was decimating the city and the reigning Pontiff, Pope Gregory I, was inspired to have an ancient icon of the Madonna and Child (reportedly painted by St. Luke on a wooden tabletop) carried in procession through the Roman streets. During the procession, Our Lady appeared above Hadrian's Tomb - now called Castel Sant'Angelo - along with a crowd of angels, including St. Michael. The archangel sheathed his sword, which signaled the abrupt end to the pestilence.
Not surprisingly, the miracle icon used in the procession inspired a popular devotion to the Blessed Virgin under the title of "Salus Populi Romani" (Salvation of the Roman People). It's now enshrined in the Basilica of Santa Maria Maggiore and this is the very same Marian image Pope Francis will pray before whenever he leaves for a trip and returns. If I recall correctly, he visited the icon recently to again invoke Mary's intercession against the current pandemic.
Consider carrying a blessed statue or icon of Jesus and/or Mary around your property in a mini-procession with members of your household... then "enthrone" it in a central place in your home. I especially recommend the Sacred Heart, the Divine Mercy image and/or Our Lady of Guadalupe. Sprinkle holy water along the way while you're at it.
There are devotional medals of all sorts, intended for varying spiritual purposes. Among the approved and widely acclaimed are the St. Benedict Medal (especially potent against evil); the Miraculous Medal (revealed to St. Catherine Laboure and particularly effective for healing); the Holy Face Medal (revealed to Bl. Maria Pierina de Micheli along with promises from Jesus for spiritual and physical protection). Incidentally, many exorcists recommend the practice of burying blessed medals at the four corners of one's yard as a way of warding off all forms of evil. Another thing to consider.
Like medals, scapulars come in many forms; each intended to be an external indication of a particular devotion to Jesus, Mary, or a Saint (e.g. St. Michael). By wearing a scapular, one places oneself under the protection of the holy person to whom the scapular is dedicated. Arguably the most popular scapular is the Brown Scapular of Carmel.

In closing, I'm hoping that by sharing this information, readers will be encouraged to practice one or more of the popular devotions I described, as part of a daily routine; an alternative way to sanctify one's day in the absence of the Mass... and please don't stop when Mass is reinstated - one can never have enough grace!
As for sacramentals, take advantage of these spiritual gifts; the divine promises attached to several of them - we, Catholics, are fortunate to have them! And if you have any doubts, just remember the Israelites when they were enslaved in Egypt - God instructed them, through Moses, to smear the blood of sacrificed lambs on their door posts as a visible signal to the angel of death to "pass over" their homes (see Exodus 12). We can do the same with this modern plague, minus the blood, of course - instead, use sacramentals. Wear them on your persons; fasten them on your doors to signal Heaven that we, too, are people of God who are looking to be spared.
So have faith in the infinite power of Christ and confidence in the blessings of the Catholic Church, which Jesus, himself, founded... and pray, pray, pray!
